Adrian Plant (Principle Curator of Entomology) is about to set off on a trip exploring biodiversity in the Brazilian Amazon. This will be the second of three planned trips hosted by the premier Amazon research institute - Instituto Nacional de Pesquisas da Amazônia (INPA) based in Manaus and funded by Brazil’s Conselho Nacional de Desenvolvimento Científico e Tecnológico. Adrian has been collaborating with fellow Diptera (fly) specialist Dr José Albertino Rafael and PhD student Josenir Camara in understanding more about Amazonian species of an aquatic fly genus called Hemerodromia. The project intends to describe all of the many new species of this group of flies found in the Amazon Basin and will look at their evolutionary relationships with other related forms around the world. It is anticipated that the researchers will be able to learn much about the reasons why certain insects occur where they do by relating the findings to ecological, biogeographical and climatic data. The team will be in the field for one month, surveying areas in the central Amazon around Manaus and also some of the upper tributaries of the river in Ecuador. Following completion of this phase of the Project, Josenir will spend six months based in Cardiff using the Museum’s extensive collections to help advance her work.

Professor Plants flowers have opened.
Professor Plants flowers have opened.
Stanford Gardening Club’s first daffodil.

I am so excited because my flowers have finally opened! They are so pretty and make me smile every time I see them! My crocus opened on 16 March and was 90mm tall, my daffodil opened one day later and was 240mm tall. Here is a photo of them.

Thankyou very much Stanford Gardening Club from Stanford in the Vale CE Primary School in England for sending me a photo of your first daffodil! Would anyone else like to send me some photos of their plants? I will put them on the website too!

Which schools have had their first flowers?

Abronhill Primary School, Culross Primary School, and Glencairn Primary School in Scotland, and Christchurch CP School, Coleg Meirion Dwyfor, Gladestry C.I.W. School, Rogiet Primary School, Ysgol Clocaenog, Ysgol Gynradd Cross Hands, Ysgol Deganwy and Ysgol Santes Tudfulin Wales, have all seen their first flowers open. In England, Arkholme CE Primary School, Burscough Bridge Methodist School, Coppull Parish Primary School, Hillside Specialist School, John Cross CE Primary School, Pinfold Primary School, Scotforth St. Paul's CE Primary School, SS Philip and James CE Primary School, St Laurence CE Primary School and Woodplumpton St. Anne's Primary School all sent their first flower records. Well done to all these schools!

One more week to go…

There is only one more week to go before the Spring Bulbs project deadline. Please remember to send in your records by the 28 March.

What do you do if your flowers have not opened by the deadline?

Please keep sending in flower data! If your flowers have not opened and you would like to carry on with your investigation then please do! When they open you can still record the flowering date and plant height on our website.

I set a deadline because every year I write a special report that gives a summary of all the data sent in so far. I need to write the report in April. All records sent in before the deadline will be included in this year’s report. Records sent in after the deadline will be added to our database and will be included in next year’s report.

All the records that you send are very important. I promise you that all your data will be included in the project and will help the investigation to be more accurate in the future.

Have you seen any signs of spring while you have been out playing? On the weekend I saw a bumblebee, a ladybird and some little baby lambs! I looked in a pond but I didn’t see any frogspawn. Have you seen any frogspawn? What other signs of spring have you seen?

Would you like to be a Nature Detective? The Woodland Trust have lots of Fun Spring Activities for you to do, click here for how to spot the early signs of Spring. Click here for lots of other fun Spring ideas.

Your questions, my answers:

Ysgol Bro Eirwg: Roedd y mesurudd glaw yn llawn ar ddydd Llun gan ei fod wedi casglu'r holl law dros hanner tymor. Rydym ni yn gyffrous iawn bod rhai o'r bylbiau wedi dechrau agor. Rydym wedi sylwi bo'r bylbiau sy'n agor yn hwyrach llawer yn llai, oes rheswm am hyn? Athro’r Ardd: Rydw i’n falch iawn bod eich blodau chi yn agor Ysgol Bro Eirwg! Da iawn chi am arsylwi mor ofalus ar y planhigion a gofyn cwestiwn gwyddonol gwych. Yr ateb yw… dwi ddim yn siŵr!! Efallai bod rhai o’r bylbiau yn llai na’r lleill wrth gael eu plannu. Gallai hyn olygu eu bod nhw’n cymryd mwy o amser i flodeuo a’u bod nhw’n llai o faint. Oes gennych chi unrhyw syniadau i’w esbonio? Sut fyddech chi’n profi eich syniadau wrth dyfu rhagor o blanhigion y flwyddyn nesaf?

Raglan VC Primary: Our flowers are blooming now! The shoots are 85 cm tall! Prof P: Do you mean 85mm tall Raglan? An 85cm tall flower would be HUGE!

Glencairn Primary School: It was very foggy on Thursday night and Friday morning! Prof P: Great weather reporting. I love fog, it’s quite spooky isn’t it?

Hillside Specialist School: Our first flower opened. By K. Prof P: Well done K and everyone else at Hillside School.

Greyfriars RC Primary School: It was fun me and R. really enjoyed it. Prof P: Hooray!

SS Philip and James CE Primary: A lot of our crocus flowers had come out over the holidays! Prof P: Fantastic! A lot of people’s flowers opened during the holidays.

Pinfold Primary School: Mystery bulbs started opening on Monday. We think they're daffodils. Other bulbs are growing very well. Prof P: Great news Pinfold.

Ysgol Terrig: our bulbs are growing great they are now 7cm tall !!!!! Prof P: Fantastic news Ysgol Terrig!

Chatelherault Primary School: During the week it has been sunny and because of this our plants has started to blossom although the flowers are still closed. We have had a lot of spiders in our pots. Prof P: Oooh, how cool! I love spiders! Their webs are so beautiful and the way they make them is so clever.

Culross Primary School: We have been very busy in P5-7 recently with trips to Scottish Parliament and also the Foodbank with a collection we organised. Sorry for the lack of records for Tuesday and Thursday! Matt is the name of my daffodil and he was the first one to flower here at Culross PS. It has been quite warm here at Culross and we haven't had any snow, so the daffodils are now beginning to grow. O's crocus is called Coco and measures 50mm. Her’s is the first crocus to flower here at Culross. Well done to O.! Prof P: Wow you sound like you have had some really interesting school trips Culross Primary. Well done for collecting for the Foodbank. I love the names you have given to your plants!

Darran Park Primary: The first crocuses flowered on the 7th of march. Their colour is purple\violet. The bees have already started collecting the pollen and they are 6 cm tall. Some of the other crocus bulbs have only just started to sprout through the soil. Prof P: Great observations Darran Park, I like your description of the crocuses as purple/violet.

Arkholme CE Primary School: Sun shining at last it is doing the flowers a world of good they have come out to see it!!! Prof P: It is doing me the world of good too Arkholme!

Many Thanks

'A day in the life' - a post for the Twitter event 'Museum Week UK'

Posted by Jennifer Evans on 21 March 2014

I begin my day by checking our general library inbox for any inquiries that we might have received over the weekend. This morning [as usual] there were quite a few but they were mercifully straight forward so didn’t take too long to answer. Next, I spent a very enjoyable hour squirreling away through our old photograph drawers for some interesting images to share with everyone during this Museum Week UK  on Twitter and what treasures I have found [but more of that to come via Tweets from @amgueddfa_lib during the week]! 

Vintage albums and photographs

 

Main Library photograph drawers

I also took some photographs of the pages of a giant old scrap book full of museum ephemera; it contains tickets, pamphlets, public announcement posters, order of services, lists of lectures and just about anything else you can stick down with heavy duty glue and sellotape…

However, my day begins in earnest with the post – as Assistant Librarian one of my main priorities is to manage the journal subscriptions. We maintain around 700 titles, a combination of paid subscriptions, exchanges and gifts. Therefore, after our Administration Assistant has opened and checked it, I weed out all the journals and record them onto our database. By doing this I am alerted to previous issues not received and will then chase them up with relevant suppliers. This time, there are no missing issues to chase but we have received a few duplicates, and [as always] these are from suppliers who categorically promised that no further duplicates would be sent out! Next, I count and measure the post so that at the end of the year I am able to supply our Principle Librarian with the total number of actual issues received and the meterage of space they will have covered. For instance, our statistics for 2013 were 1972 issues received that covered just over 11 metres of shelf space.

Next, I date stamp and separate them into departments. Our subscriptions naturally correspond with the curatorial departments, so we receive journals on the following disciplines: Art, Archaeology, Zoology, Botany, Geology and Industry and we also subscribe to more general subjects kept here in the Main Library. Once all this is done, it’s time to go and shelve them in the departmental libraries. These are dotted all around the museum so I wait until I have a little pile, normally a few days’ worth, before I go on my shelving travels.

My next task is to work through any invoices received in the post and this morning there quite a few. The way I process these has changed recently and whereas it has taken a little time to get used to the new system, it is much more straightforward and done in no time at all.

Walking into town for lunch, looking back over my shoulder...

After lunch, it’s all about the special collections! I begin by photographing books for a new post on the Museum Blog; I have been posting articles for some time now and really enjoy it. This next post I’m working on concerns books with “marginalia” and we have some excellent examples so here is a little sneak peak… 

Cambria Depicta: a tour of North Wales by Edward Pugh [1816]

 

 

Instructions for collecting and preserving insects; particularly moths and butterflies by William Curtis [1771]

The last few hours of the afternoon are spent working on a talk I will be giving in April as part of the Museum’s Behind the scenes series where the curatorial departments allow groups of visitors in to show them what goes on behind the scenes. My working title is “Curios” and the talk will be based on a small selection of our more unique items, such  as fore-edge books, annotated books, and books made from unusual materials and bindings!

On my way out I leave via the art galleries, it does take a little longer to get out going this way but it gives me the chance to browse and see what's on display and today there were two things in particular I wished to see. First, the new exhibition Wales Visitation: Poetry, Romance and Myth in Art which includes works by  David Jones, Graham Sutherland and Richard Long. And also the new Constable painting [currently on loan from the Tate]; Salisbury Cathedral from the Meadows  is a stunning work and I particularly like the dark storm clouds brooding behind the rainbow.   

A selection of books on WWI all ready for the 1914-2014 Centenary

National Science and Engineering Week

Posted by Katie Mortimer-Jones on 21 March 2014

Yesterday, Natural Sciences Staff took part in the 'Meet the Pollinators' Event run by First Campus, a partnership between higher education institutions, further education colleges and schools in South East Wales. The event was part of National Science and Engineering Week and was attended by approximately 100 Year 9 pupils from six schools. The pupils had the opportunity to speak to the curators and find out about 'a day in the life of museum scientists'.

Adrian Plant sorting samples of flies from Thailand
Sorting samples of flies from Thailand
A Malaise Trap in Deciduous Dry Dipterocarp forest, Doi Inthanon

There are two sides to exploring biodiversity. One is fieldwork, often in interesting and remote places looking for new or otherwise interesting forms of life. As an entomologist with an interest in tropical flies this often means extended trips under challenging conditions armed with a net, various kinds of insect trap, a pair of binoculars and a notebook. We know so little about tropical insects that discovery of new species is a daily occurrence and almost everything encountered is interesting for one reason or another. Unfortunately, identification of most insects in the field is quite impossible, let alone proper recognition of new species. This is where the second and perhaps less glamorous part of exploring biodiversity comes in involving long hours of study back in the laboratory when the true identity of captures may be revealed and their significance evaluated. My ongoing collaboration with Wichai Srisuka as the Entomology Section of Queen Sirikit Garden in Thailand (http://www.qsbginsects.org/) is starting to provide thousands of specimens for study. Wichai and his staff have been running a type of trap known as a Malaise trap to sample insects on the forested slopes of two of Thailand’s highest mountains, Doi Inthanon and Doi Phahompok. Specimens they have collected have been sent to me in Cardiff where I am beginning the process of ‘working up’ the samples. This involves first sorting the specimens into groups (or families and genera as systematists call higher groupings of species). Insect diversity is so great that no one person can be an expert in all of them. For this reason, many of the sorted samples are sent to collaborating colleagues around the world who are specialists in the groups concerned. I retain the rest for my own specialist studies.

Thereafter each specialist concentrates on identifying species that are already known and describing as new to science those that are not. The work does not stop there as once we have data on actual species and where they are found it can be interpreted to tell us more of, for example, the evolutionary history of a group of insects, their ecology or their biogeography (the study of how species and ecosystems are distributed geographically and historically). Furthermore, the results are of profound interest to conservation planners as they enable important areas of biodiversity to be recognised. As the work progresses I hope to feed back some of the more interesting finds through this blog.

Professor Plant recording the weather with a Super Scientist Pencil!
Wow bulb buddies – so many of you have seen you flowers open since the last blog! It must look beautiful in your playgrounds and school gardens! Thankyou for all your flower records.

Which schools have had their first flowers?

St Bernadette’s Primary School in Scotland and Abergwili VC Primary, Darran Park Primary, Henllys CIW Primary, Llanishen Fach CP School, Ysgol Bro Tawe and Ysgol Gynradd Dolgellau in Wales, have all seen their first flowers open. In England, Balshaw Lane Community Primary School, Dallas Road Community School, Golden Hill School, Holy Trinity CE Primary School, Manor Road Primary School, Red Marsh School, St Mary’s Catholic Primary School, St Michaels CE (Aided) Primary School, St Nicholas Primary School and The Blessed Sacrament Catholic Primary School all sent their first flower records. Well done to all these schools!

Only 2 weeks to send me your records

Will you be a Super Scientist this year? The deadline for sending in your records is 28 March. If you send me your weather and flower records (if they have opened) then you will be a Super Scientist! All Super Scientists will receive a Certificate and a fabulous Super Scientist pencil. You will also have the chance to win a Nature Activity trip or some seeds to grow your own Sunflowers!

Why not send me your drawings for the Daffodil Drawing Competition? The deadline is also 28 March. For this competition I will be looking for botanical illustrations – these are pictures of plants drawn in a scientific way. Please send me your lovely drawings, but I would also like them to have clear labels to show the different parts of the Daffodil. You can follow this link to see the winners and runners up from last year’s competition. Winners will get a bird watching kit with mini binoculars for their class, runners up will get flower seeds to grow!

My plants in pots have still not flowered, but over at St Fagans National History Museum the crocuses growing in their garden look beautiful. The bees like them too, as you can see in the photo! Can you see that the bumblebee has yellow pollen all over its head and body? When it flies off to a different crocus it will pass the pollen on – this is how flowers are fertilised!

Your questions, my answers:

Raglan VC Primary: Still no sign of the flowers this week! We are having some good weather. Prof P: Don’t worry Raglan School, mine haven’t flowered yet either. Hopefully the good weather will help our plants to flower.

Cutteslowe Primary School: Monday 17th - school closed, no heating or hot water. Prof P: Brrrr that sounds very chilly.

Manor Road Primary School (Lancashire): One of are crocus bulbs are starting to flower. Prof P: Fantastic news Manor Road, Congratulations!

Chatelherault Primary School: Wk 10: Most of our plants have started to too grow. It has raining a lot and some snow. Prof P: We didn’t have any snow at all in Cardiff this year, but we did have lots of rain.

The Blessed Sacrament Catholic Primary School: It has been so exciting this week as the buds all suddenly started to appear and on Friday some crocus flowers opened! The daffodils have suddenly grown and we know it won't be long before they too flower. They just love the sunshine! Prof P: Hooray! It’s such a lovely feeling to see your flowers open isn’t it?

Greyfriars RC Primary School: S - ten of our crocuses have budded. Prof P: Great news S. at Greyfriars, I’m sure the other crocuses won’t be far behind.

Dallas Road Community Primary School: Super Fun!!! Prof P: I’m so glad you think so Dallas Road! Science IS Super Fun!

Many Thanks

The 1st flower records for Scotland!

Posted by Catalena Angele on 7 March 2014

Congratulations to Ladywell Primary School for sending in the first flower records for Scotland! Lakeside Primary School in Wales have also sent in their first flower records – their first crocus and first daffodil opened in the same week! Great work bulb buddies.

Three weeks to go… The deadline for sending in your weather and flower records is Friday 28 March, so there are just three weeks to go!

If you have been keeping records but haven’t sent them to me yet then please send them soon – all your weather and flower records are really important to me! Every record you send in will make the Spring Bulbs Investigation better and more accurate.

Don’t worry if your flowers haven’t opened yet, a lot can happen in three weeks, especially if the sun shines!

Would you like to do a Super Scientific Investigation with your plants? I have put together some great ideas for experiments you can do in your school! Can you trick your crocus? Can your daffodil move? Click here to have a look: Professor Plant’s investigation ideas. As well as exciting experiments you will also find my favorite Spring Poem here! It is about daffodils and this is the first verse:

 

Daffodils

I wander’d lonely as a cloud

That floats on high o'er vales and hills,

When all at once I saw a crowd,

A host, of golden daffodils;

Beside the lake, beneath the trees,

Fluttering and dancing in the breeze.

By William Wordsworth (1770-1850)

 

Beautiful! Have you ever tried to write a poem about Spring? Or about your favourite flower? Why not give it a go?

Your questions, my answers:

Ladywell Primary School: We have had our computer system upgraded in school and it has been difficult for us to send weekly weather reports because we lost a lot of data which was stored on our apple mac and which we cant convert to PC. However we have been taking temperatures and it has not really been cold and we have had a lot of rain. Some of our plants didn't grow very well but our first daffodil opened today 25th February and it is 28 cm tall. We have another one about to open and some others not far away. We hope this is ok with you and we will send more information soon. Prof P: Sorry to hear you have had computer trouble Ladywell School, don’t worry, I completely understand. Thanks very much for sending your first flower record! Keep up the good work and send in your other flower records when they open.

Lakeside Primary: Daffodil comment: Only one is open and the one that has opened has only got half a pot of compost, we think it was knocked over and some soil lost so perhaps less soil has led to quicker flowering, but why? Prof P: Great question Lakeside! Do you have any ideas? This is my theory: A bulb closer to the surface may flower sooner because it warms up quicker and has less soil to push through when it starts to grow. So why don’t we plant them all close to the surface? Well, if there is a very cold winter the frost can damage bulbs that are too close to the surface, and then they may not grow at all.

The Blessed Sacrament Catholic Primary School: We all brought our wellies into school this week so that we can go out and look at our bulbs whatever the weather. We went to check on them all on Friday and measured how tall the leaves were, and started recording them in a table like we had been doing in maths. We hope to do this every week now then we can make a graph of the results. Still no sign of flowers yet! Prof P: What a fantastic idea! I love making graphs, they are a great way to see what the numbers are telling me. You must be very dedicated scientists to bring your wellies in to school so you can measure your leaves. Well done, I am very impressed!

Many Thanks

Signs of Spring

Posted by Catalena Angele on 28 February 2014
My tallest daffodil is 80mm tall.
My crocus is only 30mm tall.
Daffodils and crocuses blooming in Bute Park, Cardiff.

The sun is shining through my window here in Cardiff and it feels like Spring has arrived! My own plants are not ready to flower yet, my tallest daffodil is 80mm tall and my crocus is still only 30mm tall, but I am sure they will like the sunshine! I took a photo this morning of daffodils and crocuses blooming in Bute Park, Cardiff, aren’t they beautiful?

Which schools have had their first flowers?

Ysgol Glan Cleddau in Wales has reported their first crocus has opened, and Archbishop Hutton's Primary School in England have reported that their first daffodil has opened! Congratulations and well done for sending in your records.

Rougemont Junior School in Wales sent me this message: Well Professor Plant great excitement here at Rougemont School ... our MYSTERY BULBS have started to flower! They look very healthy, shorter in stem than the other Daffodil bulbs that we planted too. We think they could be Narcissus maybe Tete a tete? Will send a photo soon.

Prof. P: That is very exciting Rougemont School, and well done for investigating what kind of Narcissus they might be – Great work! I look forward to seeing your photos.

And Kilmaron Special School in Scotland said: THIS IS AN OBSERVATION OF LAST YEARS BULBS. We have been monitoring last years crocus and daffodil bulbs to see if older bulbs flower before newly planted bulbs. After our 1/2 term holiday we came back to find the crocus bulbs planted in the pots from last year had opened while this years crocus bulbs look to be about 7-10 days behind in their flowering. We are expecting to post this years results towards the end of next week.

Prof. P: This is really excellent monitoring and investigating Kilmaron! I am very impressed. You are right that older bulbs usually flower sooner than new baby bulbs, one reason for this is that they have had an extra year to grow and store up food.

I wonder where flowers will open next? You can see where flowers have opened so far by looking at this map. If your flowers haven’t opened yet then watch them closely as they may open very soon!

Remember to send me you flower records as soon as your flowers open. To remind yourself what to do, please use my PowerPoint presentation how to keep flower records, and read the What and when to record page on my website.

TOP TIPS:

  1. Every pupil in the class can send in their flower record! All the data that is sent in is used to create an average flowering date for each school. Watch the crocus chart and daffodil chart to see the tables change as the data comes in. It is really important that each pupil sends in their record - so the website can calculate the average flowering date for your school.
  2. Daffodils tilt their heads downwards just before opening. This prevents them from filling with rain after they open.
  3. You need to all send in your flower records to win the Super Scientist Competition!

Your questions, my answers:

Ysgol Terrig: It snowed heavily on Monday morning and stopped about lunch time. Our bulbs are starting to grow :) Prof P: I’m glad your bulbs are growing, did you go out to play in the snow?

Raglan VC Primary: We missed Tuesday because it was raining cat's and dog's, and we had bike training. Prof P: I love that saying! Can you imagine what it would be like if it really did rain cats and dogs? How would we measure that in our rain gauge?

Chatelherault Primary School: Sorry we did not record information on Thursday because we were away all day at a school trip. We were excited to see little green shoots in some of the plants. Prof P: Thanks for letting me know Chatelherault, I hope you had fun on your school trip.

Greyfriars RC Primary School: The plants are growing well and it's wonderful seeing them grow up. The mystery bulbs are really a mystery. from A and A :) Prof P: I hope your mystery will soon be solved Greyfriars!

Arkholme CE Primary School: Unfortunately the plant pots are standing in water this week. Let's hope next week is drier. The mystery bulbs are growing better than the others. Flower buds just appearing. From H. Prof P: I am sure your plants will survive the rain Arkholme, keep watching those flower buds!

Many Thanks

Museum records largest earthquake in UK since 2008!

Posted by Andrew Haycock on 25 February 2014
The Bristol Channel earthquake recorded on the Museum seismograph
Evolution of Wales seismograph display showing the Bristol Channel earthquake
The largest earthquake in the UK since February 2008!
Detail of the 4.1 magnitude Bristol Channel earthquake

The British Geological Survey (BGS) reported a 4.1 magnitude earthquake in the Bristol Channel at 13:21 GMT on 20th February 2014. The event was also recorded on the Museum seismograph in the Evolution of Wales Gallery at National Museum Cardiff.

This is the largest earthquake in the UK since the 5.2 magnitude Market Rasen quake in February 2008.

The earthquake was felt widely across South Wales, Devon, Somerset and western Gloucestershire. Reports to the BGS described “felt like the vibration of a large vehicle passing the building”, “the whole house seemed to move/wobble back and forth a few times”.

The earthquake epicentre is estimated to be 18 km NNW of Ilfracombe at a depth of 3km.

Although the UK is not located on a plate margin, on average 200 – 300 earthquakes a year are recorded in Britain. Most earthquakes are so small they are not felt by people, and can only be picked up by the sensitivity of a seismometer.

The UK is located on the European plate. Tension is built up in the plate as new crust is created at the Mid Atlantic Ridge, and the plate is slowly pushed towards the north-east.

There are several long-active faults in the Bristol Channel which include the Bristol Channel – Bray fault. Once faults form, they create weak zones in the crust that can be reactivated time and time again. Movement occurred along one of these faults as tension in the crust was released.

On average an earthquakes of this size affects mainland Britain once every 2 years.

The largest recorded mainland event is the magnitude 5.4 earthquake on the Lleyn Peninsula in July 1984, where movement occurred along a long-active pre-existing fault.

 

 

Rain, rain and more rain

Posted by Catalena Angele on 21 February 2014
Met Office Map showing rainfall in the U.K. in January 2014

What a very wet and rainy January we had bulb buddies! It felt like it rained nearly every day! But how much rain did we really have compared to average?

Weather Scientists at the Met Office have created this map of the U.K. to show how much rain we had in January. You can have a closer look by following this link.

How did they calculate average rainfall? The Met Office Scientists have been keeping weather records for a very long time! They added up how much rain fell in January for 30 years (from 1981 to 2010) then divided by 30 to calculate how much rain fell on average each year.

Can you see the two different shades of dark blue? Rainfall in these areas was between two and three times the average for January. Can you see the black areas in the south of England and in eastern Scotland? Rainfall in these areas was more than three times the average for January!

Top tip for using this map:

  • 100% of average means that the rain was the same as average.
  • 200% of average means that there was twice as much rain as average.

Can you find where you live on the map? What colour is the map where you live? How much rain fell in your area? Is it more than average? Or less than average? You may want to ask your teacher to help you answer these questions!

Your questions, my answers:

Gladestry C.I.W. School: Our school was closed on Thursday because of a power cut so our head teacher recorded the results that day. Prof P: We done to your head teacher! I am very glad your head teacher is helping you with your investigation.

St Mellons Church in Wales Primary School: Hello Professor Plant. It has been so windy this week that our thermometer has blown off the wall and broken. We have been using the car thermometer. L, J and L-b. Prof P: Hello L, J and L-b at St Mellons School! I am very sorry to hear that your thermometer is broken, I will email your teacher and arrange to send you a new one. Well done for your quick thinking in using the car thermometer.

Bleasdale CE Primary School: It is very cold and wet. Prof P: I agree BleasdaleSchool!

Ysgol Gynradd Dolgellau: Yn anffodus mae ein thermometr wedi torri ar ol cael ei chwythu gan y gwynt mawr yn ystod yr wythnos. Athro’r Ardd: Trueni mawr i glywed hyn Ysgol Gynradd Dolgellau. Bydda i’n e-bostio eich athro i drefnu anfon thermomedr newydd atoch chi.

Manor Road Primary School (Lancashire): on Wednesday there was a red weather warning but luckily the plants stayed in place. Prof P: I’m very happy to hear that your plants are okay!

Stanford in the Vale Primary School: It is very rainy here but we are not flooded. Prof P: I am very glad to hear that Stanford! What colour is the rainfall map is your area?

Burscough Bridge Methodist School: The heavy gales have caused the rainfall measurements to be unreadable as the measuring vessel was continually disrupted and blown over. Prof P: Gosh it must have been very stormy. Thanks for letting me know, keep up the good work!

Many Thanks
