Helo Cyfeillion y Gwanwyn,

Diolch i’r ysgolion sef wedi rhannu ei chofnodion blodau! Cofiwch i wneud yn siŵr bod y dyddiad yn gywir a bod taldra'r planhigyn wedi ei chofnodi yn filimedrau. Rydym wedi cael cofnodion yn dweud bod planhigion wedi blodeuo ym mis Ebrill a hefo disgrifiadau am grocws a chennin pedr anhygoel o fyr!

Os ydych yn gweld bod eich cofnodion angen ei chywiro, yna yrrwch rhai newydd i mewn hefo esboniad o hyn yn y bwlch sylwadau.

Rwyf wedi mwynhau darllen y sylwadau hefo’r cofnodion tywydd a blodau dros y pythefnos diwethaf. Rwyf wedi atodi rhai o’r sylwadau isod. Daeth cwestiwn diddorol o Ysgol Stanford in the Vale, yn gofyn a oes rhaid cofnodi pob blodyn i’r wefan os mae’r dyddiad a’r taldra'r un peth? Mae’n bwysig i rannu’r cofnodion i gyd, oherwydd mae'r nifer o blanhigion sydd yn blodeuo ar ddyddiad unigol a’r taldra'r planhigion yn effeithio'r canlyniadau.

I weithio allan taldra cymedrig eich ysgol ar gyfer y crocws a’r cennin pedr, adiwch bob taldra o’r crocws neu’r cennin peder, a rhannwch hefo'r nifer o gofnodion. Felly os oes genych deg cofnodion o daldra i’r crocws, adiwch y rhain at ei gilydd a rhannwch hefo deg i gael y rhif cymedrig.

Os oes gennych un blodyn hefo taldra o 200mm ac un blodyn hefo taldra o 350mm, fydd y rhif cymedrig yn 275mm. Ond, os oes gennych un blodyn hefo taldra o 200mm a deg hefo taldra o 350mm fydd y rhif cymedrig yn 341mm. Dyma pam mae’n bwysig i gofnodi pob cofnod blodau.

Mae pob cofnod blodau yn bwysig ac yn cael effaith ar y canlyniadau. Os nad yw eich planhigyn wedi tyfu erbyn diwedd mis Mawrth, plîs wnewch gofnod data heb ddyddiad na thaldra ac esboniwch pam yn y bwlch sylwadau. Os mae eich planhigyn yn tyfu, ond ddim yn blodeuo erbyn diwedd mis Mawrth, yna plîs cofnodwch daldra'r planhigyn, heb ddyddiad blodeuo, ac esboniwch hyn yn y bwlch sylwadau.

Cadwch y cwestiynau yn dod Cyfeillion y Gwanwyn! Mae 'na nifer o adnoddau ar y wefan i helpu hefo’r prosiect. Unwaith mae eich planhigyn wedi blodeuo, fedrwch greu llun ohono a defnyddio hyn i labelu'r rhannau o’r planhigyn! Hoffwn weld ffotograff o rain, a wnâi rhannu pob un sy’n cael ei yrru ata i ar fy blog nesaf!

Daliwch ati gyda’r gwaith called Cyfeillion y Gwanwyn,

Athro’r Ardd

Eich sylwadau:

We’ve had lots of lovely comments about your plants, sent in with both weather and flower data:

Ysgol Y Wern: Mae'r bylbiau i gyd wedi egnio ac mae sawl blodyn crocws i'w weld!! Mae'r bylbiau ddirgel yn edrych yn diddorol iawn gyda streipiau ar y ddail!

Ysgol Pennant: Mi roedd yn hwyl iawn i tyfu crocws a i weld o.

Stanford in the Vale Primary School: 17 daffodils have all flowered on the same day! Do we still have to enter individual flowers? They all measure the same height! Regards R.

Professor Plant: Hi Stanford in the Vale, I’ve answered your question in detail above as it was the star comment this week! It’s a very good question, but all of the individual flower records are important and can help us to create a bigger picture of the results! I have a special task for you this week, why not work out your school’s average flowering date for this year and last year, and let me know whether your plants flowered earlier or later on average this year! There’s a fun game on BBC Bitesize to help you with Mode, Median, Mean and Range! http://www.bbc.co.uk/bitesize/ks2/maths/data/mode_median_mean_range/play/

St Robert's R.C Primary School: I am so glad my bulb has flowered.

St Mary's Primary School: Our first crocus flower has opened. We are all really excited.

Ellel St John's CE Primary School: They've grown quite quickly and are just opening.

Stanford in the Vale Primary School: We will send photographs later today. The crocus have a beautiful radiant deep purple colour.

Rougemont Junior School: Our Crocus are flowering and our Daffodils are growing well. We hope it will be sunny tomorrow. I think we are in luck!!!

Tonyrefail Primary School: Hi Professor Plant most of our plants have grown. We are measuring them. Nine of are crocuses have flowered.

Garstang St. Thomas' CE Primary School: We had a couple of frosty mornings this week but our crocus plants are still flowering and all our daffodils have buds on them now.

Loch Primary School: We are happy to see our plants growing!

Tonyrefail Primary School: Our Crocuses have also started to grow.

Garstang St. Thomas' CE Primary School: We were back into school on Tuesday. We had a surprise as J's crocus had blossomed and a lot of us have noticed our plants have grown buds so we are all on stand-by to record our blooms too. Storm Doris came on Thursday so we didn't catch all the rain as most of it was sideways! Luckily none of our bulb pots were blown over.

Professor Plant: Fantastic Bulb Buddies, I'm glad to hear you are watching your plants so carefully! Don't worry about sideways rain as the rain gauge is designed to collect a sample of rainfall. Keep up the good work Bulb Buddies!

We’ve had lots of insightful comments about the weather, and many of you commented on storm Doris. More information on storm Doris can be found here: http://www.metoffice.gov.uk/barometer/uk-storm-centre/storm-doris

St Robert's R.C Primary School: Storm Doris wedi chwythu y brigau oddiar y coed ar dydd iau.

Ysgol Pentrefoelas: Yn wlyb iawn ar Dydd Llyn ond wedyn yn mynd yn sych.

Ysgol Y Wern: Oer iawn, iawn wythnos yma. Wedi bwrw eira ar ddydd Gwener.

Carnbroe Primary School: We had lots of rain on Tuesday and we were slipping about the garden while we were checking on our plants. Still no flowering yet. Nearly everyone's bulb has begun to show shoots. C's bulb has not come through the soil yet.

Professor Plant: Ooo be careful if the ground is slippery Bulb Buddies! I hope C’s plants grow, but if they haven’t grown by 31^st March please let me know by entering a flower record but leaving the date and height blank. It’s as important to record this as it is flower records!

Stanford in the Vale Primary School: Hello, this week has been quite chilly and on Monday it was icy. It has been rainy to. Bye Bye.

Rougemont Junior School: It's going well. Hopefully it will be sunny tomorrow.

Arkholme CE Primary School: This week the Temperature has gone down quite a bit on Thursday. And there was not a lot of rain on Friday and Wednesday are bulbs are starting to grow so we are quite pleased. Thank you very much.

Stanford in the Vale Primary School: Hello, On monday it was teacher training day so we couldn't record it. But this week it has been hot and cold. On Thursday we had storm Doris so it was very cold. Bye,bye.

Ysgol Rhostyllen: This is fun.

Our Lady of Peace Primary School: I liked doing the temperature because it was fun.

Broad Haven Primary School: Yr 5 are in LLangrannog this week so we are recording the weather. Rain and gales at the end of the week.

Professor Plant: Thank you for filling in Bulb Buddies, I hope you enjoyed the project! Good work.

Helo Cyfeillion y Gwanwyn,

Rwy’n gobeithio y cafodd bawb hanner tymor gwych. Mae’r cofnodion blodau cyntaf i mewn, sy'n golygu fod haf yn wir ar ei ffordd!  Plîs rhannwch luniau o’ch blodau, eich gorsafoedd tywydd ac unrhyw arwyddion fod yr haf yn dod!

Rwyf isio rhoi gwybod am adnoddau addysg newydd ar gael trwy Gasgliad y Werin Cymru. Mae Casgliad y Werin Cymru yn fenter a gwefan wedi ei hariannu gan Lywodraeth Cymru a’i rhedeg trwy bartneriaeth rhwng Amgueddfa Cymru, Llyfrgell Genedlaethol Cymru a’r Comisiwn Brenhinol Henebion Cymru. Mae'r wefan yn le i gasglu a rhannu elfennau o hanes Cymru a'i bobl. Mae'r safle yn adnodd i bawb, a gall unrhyw un gyfrannu. Effaith hyn yw bod straeon newydd yn cael eu hadrodd a’u cofnodi am y tro cyntaf, a’u bod nhw ar gael i bawb sydd hefo diddordeb.

Daliwch ati gyda'r gwaith da Gyfeillion y Gwanwyn,

Athro’r Ardd

Helo Gyfeillion y Gwanwyn,

Mae nifer o ysgolion wedi cofnodi bod eu Cennin Pedr a Chrocws wedi cychwyn tyfu. Mae rhai ysgolion wedi nodi bod eu planhigion yn edrych yn agos at flodeuo. Fallu, mae'n amser da i drafod rhan nesaf y prosiect - cofnodion blodeuo! Mae adnodd ar y wefan Bylbiau Gwanwyn i Ysgolion o dan y teitl 'cadw cofnodion blodau'. Mae'r ddogfen hon yn dweud wrthych sut i gadw cofnodion blodau, pa offer sydd angen ei ddefnyddio a’r dulliau ar gyfer casglu gwybodaeth.

Oedd y pecyn adnoddau a anfonwyd i'ch ysgol yn fis Hydref yn cynnwys siart blodeuo Crocws a siart blodeuo Cennin Pedr.  Gallwch ddefnyddio'r rhain i gofnodi'r dyddiad mae eich blodau yn agor ac uchder eich planhigion ar y dyddiad hwn. Wedyn, gallwch rannu dyddiad blodeuo ac uchder eich planhigyn ar y dyddiad hwn i wefan Amgueddfa Cymru. Unwaith mae'r diwrnod blodeuo cyntaf wedi ei gofnodi ar gyfer eich ysgol, bydd blodyn yn ymddangos wrth ymyl eich ysgol ar y map ar wefan Amgueddfa Cymru.

Mae rhywfaint o ddryswch wedi bod ynghylch pryd i gofnodi dyddiad blodeuo ar-lein. Gallwch fonitro taldra eich planhigion bob wythnos a gadael i mi wybod yn yr adran ‘sylwadau’ wrth i chi gofnodi’r tywydd. Ond dim ond wedi i’r planhigyn flodeuo y dylech gofnodi ‘dyddiad blodeuo’ a thaldra’r planhigyn ar ddiwrnod blodeuo.

Mae rhywfaint o ddryswch wedi bod ynghylch pryd i gofnodi dyddiad blodeuo ar-lein. Gallwch fonitro taldra eich planhigion bob wythnos a gadael i mi wybod yn yr adran ‘sylwadau’ wrth i chi gofnodi’r tywydd. Ond dim ond wedi i’r planhigyn flodeuo y dylech gofnodi ‘dyddiad blodeuo’ a thaldra’r planhigyn ar ddiwrnod blodeuo.

Edrychwch ar y llun o Gennin Pedr yn Sain Ffagan. Cafodd y llun ei dynnu ar ddiwrnod oer, felly nid oedd y blodau wedi agor yn llawn. Ond, gallwch weld pa rai sydd wedi blodeuo trwy edrych yn ofalus. Os yw’r holl betalau i’w gweld yn glir yna mae’r planhigyn wedi blodeuo. Cyn blodeuo mae’r petalau yn cael eu gwarchod gan gasyn tynn.

Pan fydd y blodyn wedi aeddfedu, a’r tywydd yn ddigon cynnes, bydd y casyn yn dechrau agor. Gall hyn gymryd ychydig oriau neu rai dyddiau! Efallai y gallwch weld hyn yn digwydd, os wnewch chi wylio’r planhigion yn ofalus iawn! Pan fyddwch yn gallu gweld yr holl betalau a’r casyn wedi disgyn gallwch fesur taldra’r blodau a chofnodi hyn ar y wefan. Wedi i chi wneud hynny bydd blodyn yn ymddangos ar fap yn dangos lle mae eich ysgol.

Gallwch fesur uchder eich planhigion i weld pa mor sydyn mae nhw’n tyfu. Os yw’r planhigion yn dal yn fach gallwch eu mesur o dop y pridd. Ond, pan fyddwch yn mesur er mwyn cofnodi ar y wefan, dylech fesur o dop y pot blodau i bwynt uchaf y blodyn.

Ydych chi wedi cymharu uchder y blodau yn eich dosbarth? Oes yna wahaniaeth mawr yn uchder y planhigion a pha mor aeddfed ydyn nhw, neu ydyn nhw i gyd yn debyg? Beth am y planhigion sydd wedi’u plannu yn y ddaear? Yw’r rhain yn fwy na’r rhai mewn potiau? Pam hynny tybed? Gallwch ddweud beth ydych chi’n feddwl yn yr adran ‘sylwadau’ wrth i chi gofnodi’r tywydd yr wythnos hon!

Gyrrwch eich straeon a lluniau i’r blog blodau a dilynwch Athro’r Ardd ar Twitter!

Daliwch ati Gyfeillion y Gwanwyn!

Athro’r Ardd

Diolch am rannu newyddion am eich planhigion Cyfeillion y Gwanwyn:

Ysgol Deganwy: Most of the plants have started to grow.

Henllys CIW Primary: About all the bulbs have sprouted.

Ysgol Pentrefoelas: Dim glaw. Braf efo awyr goch bob nos a bob bore! Deilen 3 Cenin wedi dod i'r golwg yn y potiau. Wedi bod yn gynnes a phawb yn chwarae "British Buldogs" bob dydd heb gotiau!

Carnbroe Primary School: The week started off really cold and frosty but as the week went on the temperature rose and we had some rain. More shoots are beginning to bud. We are hoping that our bulbs will flower soon.

Arkholme CE Primary School: It has been wet and mild this week, and most of the bulbs have sprouted already. The crocus bulbs and daffodils have sprouted as well as the ones in the pots, and the ones in the ground have grown the quickest as well. Best wishes E and A.

Trellech Primary School: We have noticed that our bulbs have started to appear above the soil. We think it is because it has been a lot milder this week.

Trellech Primary School: We really enjoyed collecting the data.

Our Lady of Peace Primary School: I can't believe it is nearly over. We are enjoying it.

Auchenlodment Primary School: We have started to measure the shoots and are excited to see how they grow. 2 of the mystery bulbs have just started to sprout. No sign of the daffodils we planted in the ground.

Boston West Academy: This week we only have two more to start sprouting; it’s also been very cold and hot but also very wet. One of our mystery bulbs are nearly starting to flower☺!!!

St Robert's R.C Primary School: It's been a dry week this week. There a few signs of growing!

Ysgol Deganwy: Nearly all of the plants are growing.

Carnbroe Primary School: We didn't have lots of rain this week and it was very cold. Our bulbs are beginning to sprout.

Tonyrefail Primary School: On Tuesday we noticed 4 of our Daffodil plants have stated to push up through the soil. Yeay!

Garstang St. Thomas' CE Primary School: We've had some frosty mornings but our daffodils are still starting to appear through the soil. The ones in the garden are growing faster!

Henllys CIW Primary: It was pretty cold but no rain. Quite a few plants are growing!

St. Nicholas Primary School: The bulbs have sprouted.

Arkholme CE Primary School: This week has been dry and cold. We have been checking our bulbs all week but because of the cold they haven't grown much. Have a good week.

Ysgol Deganwy: The plants have started to grow and it's been super cold!

St Ronan's Primary School: Most of the daffodil in pots, are at least 2 to 3 cm.

Helo Cyfeillion y Gwanwyn,

Diolch yn fawr i'r rhai ohonoch sef wedi rhannu eich lluniau, rwyf wedi atodi'r rhain ar y dde. Rwy’n hapus i glywed bod rhai o'ch planhigion wedi cychwyn blaguro. Yn fy Blog diwethaf gofynnais a ydych yn credu byddai'r Crocws neu'r Cennin Pedr yn blodeuo’n gyntaf. Nawr rwyf isio gymryd golwg agosach ar y ddau blanhigyn i weld sut fedrwn ni gwybod nhw’n wahân. Rwyf wedi atodi llun o Grocws ifanc a Chennin Pedr ar y dde, mae'r rhain wedi eu labelu yn glir. Beth yw'r gwahaniaethau rhwng y ddau blanhigyn?

A fedrwch ddweud os eich Cennin Pedr, Crocws neu'r ddau syn blaguro? Pa mor dal ydyn nhw? Mae'n ddiddorol i gymharu uchder y ddau blanhigyn ac i sylwi faint y maent yn tyfu bob wythnos.

Gwyliwch eich planhigion yn ofalus fel medrwch gofnodi'r dyddiad mae’r planhigion yn blodeuo, a thaldra eich planhigyn ar y diwrnod. Wedyn, fedrwch rannu’r wybodaeth ar y wefan.  Mae adnodd o'r enw 'Cadw Cofnodion Blodau’ ar dudalen we Prosiect Bylbiau'r Gwanwyn i Ysgolion, o dan 'Adnoddau Addysgu': https://amgueddfa.cymru/bylbiau-gwanwyn/

Adnodd arall fysa’n ddiddorol i ddefnyddio nawr gallwch weld eich bylbiau’n tyfu yw ‘Gwnewch lyfryn origami bach eich hun!’. Mae hyn ar y wefan hefyd, ac mae’n edrych ar gylch bywyd bwlb.

Os ydych yn cwblhau unrhyw weithgaredd oddi ar y wefan, neu yn creu un eich hun yn y dosbarth, plîs rhannwch eich gwaith gyda ni. Mae’n ddiddorol i weld y gwaith da chi’n wneud.

Diolch am rannu eich darlleniadau tywydd. Rwyf wedi ateb rhai o'ch sylwadau yn isod.

Eich sylwadau:

Sylwadau am y tywydd:

Ysgol Pentrefoelas: Dim llawer o law a chynnes. Pawb yn ymarfer pel-droed at y twrnament ac felly yn gallu bod allan bob dydd. Llawer o blant wedi cael balaclafas capiau anifeiliaid i gadw eu pennau'n gynnes.

Athro’r Ardd: Gobeithio gwnaethoch yn dda yn y twrnamaint! Rwy’n hoffi meddwl am bawb rhedeg o gwmpas hefo capiau anifeiliaid gwahanol! Am anrhegion da i gael am Nadolig!

Arkholme CE Primary School: We had quite a wet week. It was fairly warm and some bulbs are sprouting from last year.

Broad Haven Primary School: We hoped we would have snow. But we just had a really cold wind -Northerly- and a bit of sleet. The sea was very rough and the waves came over the road.

Darran Park Primary: The temperature has lowered throughout the week. There has been a little amount of rain.

YGG Tonyrefail: It wasn't very wet this week but it was quiet warm.

Stanford in the Vale Primary School: Hello, the mornings of this week have been very cold and icy. We have had a rainy week this week. bye,bye

Auchenlodment Primary School: It has been a very warm week even though it's January!

Broad Haven Primary School: A cloudy week until today it is very sunny but cold

Sylwadau am y prosiect:

Ysgol Bro Ogwr: Yr wythnos yma fe dorrodd y dyfais i gasglu dwr ar ddydd Iau pan ddaeth y glaw. Roedd split ynddo a mae'r athro wedi defnyddio duct tape i rhoi fe yn ol at ei gilydd. Fe all hyn olygu bod ein canlyniadau ni ddim yn hollol gywir.

Athro’r Ardd: Diolch am roi gwybod am y broblem. Da iawn i'ch athro am drwsio’r mesurydd glaw . Gadewch i mi wybod os ydych yn angen mesurydd glaw newydd.

Sylwadau am eich planhigion:

Ysgol Pennant: Maer bylbiau yn dechrau tyfu!

St Clare's Catholic Primary School: Some of our bulbs have started to shoot this week!

Ladygrove Park Primary School: nothing growing yet

Professor Plant: Don’t worry Bulb Buddies, I’m sure you will see something soon!

Garstang St. Thomas' CE Primary School: It was a really rainy week but it was quite warm outside. We have noticed some of our bulbs are growing because we can see pointy green shoots poking through the soil!

Arkholme CE Primary School: The bulbs in the pots are just starting to sprout and look healthy. We have just noticed that last years plants are also growing. As usual the days in January have been wet so we think that helped them to grow.

Henllys CIW Primary: Our biggest plant is a daffodil that is 2.5 cm tall.

Am dywydd diddorol Gyfeillion y Gwanwyn! Mae nifer ohonoch wedi sylwi ar faint mo cynnes oedd mis Rhagfur, a rhydych yn iawn! Wrth gymharu ein canlyniadau o 2011 i 2016, gallwn weld a Rhagfur 2016 oedd yr ail gynhesach ers dechrau'r prosiect. Ddim ond yn Rhagfur 2015 oedd tymherau yn uwch! Welodd Rhagfur 2016 hefyd y glawiad isaf ers dechrau'r prosiect, ac oriau golau haul gyfartaledd.

Beth am weithio allan eich darlleniadau cyfartal ar gyfer mis Tachwedd a Rhagfyr a chymharu heu’n hefo’r darlleniadau yn y tabl?

Mae nifer ohonoch wedi rhoi gwybod bod eich planhigion wedi cychwyn tyfu! Ydych chi'n meddwl y bydd y Crocws neu’r Cennin Pedr yn ymddangos yn gyntaf? Beth am edrych drwy’r adroddiad llynedd a chymharu'r dyddiau blodeuo ar gyfer y Crocws a’r Cennin Pedr i'ch helpu penderfynu pa un fydd yn tyfu’n gyntaf?

Mae fy mhlanhigion wedi cychwyn tyfu hefyd, rwyf wedi atodi llun. Plîs rhannwch eich lluniau fel bydda’n yn gallu dangos nhw ar fy blog nesaf!

Eich sylwadau:

Mae nifer ohonoch wedi sylwi ar pa mor gynnes oedd mis Rhagfyr ac wythnos gyntaf mis Ionawr:

Ysgol Pentrefoelas: Pawb allan yn chwarae yn y cae drwy'r wythnos gan ei bod yn braf iawn ac awyr glir bob dydd. Pawb yn rhyfeddu wrth weld mynyddoedd Eryri i gyd efom copaon clir drwy'r wythnos. Tywydd anhygoel o braf.

Athro’r Ardd: Rwy’n falch i glywed oedd gen ti dywydd braf. Mae’n siŵr oedd o’n rhyfedd weld y mynyddoedd heb eira ym fis Rhagfur. O be rwy’n dallt, bydd yr eira yn ôl wythnos yma!

Auchenlodment Primary School: What a warm week for December!

Lawhead School: We had very little rain this week and it was quite sunny too.

Hudson Road Primary School: Lots of warm days but quite windy!

Trellech Primary School: It was a lot warmer this week compared to last week. We can’t wait for our bulbs to grow.

Broad Haven Primary School: This week has been warmer and we have had fog. We break up next week.

Darran Park Primary: The temperature has risen over the week. Not much rainfall this week, quite a dry week.

Boston West Academy: There was barely any rain this week and all of the other weeks did have a lot of rainfall. The temperatures are very weird because they were on and off.

Stanford in the Vale Primary School: Hello, this week it has been warm, amazing because it is getting closer to Christmas. Some of the bulbs have started to pop up. Merry Christmas from Stanford!

YGG Tonyrefail: It was quite a warm week for December.

Severn Primary: We are surprised the plants are beginning to come up because it was so cold last week. It was much, much warmer this week. We had misty rain which didn't seem to end up in the collecting jar.

St Robert's R.C Primary School: Not too cold for the start of the year.

Mae llawer ohonoch wedi rhoi gwybod bod eich planhigion 'di cychwyn tyfu! Newyddion gwyllt Cyfeillion y Gwanwyn!

Beulah School: Mae rhai o'n bylbiau wedi dechrau tyfu.

Pirnmill Primary School: 20th December 2016. We noticed that three of the daffodils planted in the open ground had shoots poking through the soil. Is this too early?

Professor Plant: Hi Pirnmill Primary. A few schools have reported that their flowers have begun to bud! Mine have just poked their heads out of the soil! They began to appear about this time last year, but this is earlier than preceding years. Well done for looking after them so well!

Auchenlodment Primary School: We started back at school on Thursday. Some of our bulbs have started to sprout, we are all very excited!

Broad Haven Primary School: A frosty start to the week on Tuesday. On Friday it rained all day. Green shoots are appearing.

Diolch am yrru newyddion diweddaraf ac adborth ar y prosiect:

St Paul's C.I.W. Primary: Hello Pr.plant we have had a good week one girl who is a rainfall child said she is having a good time but she is sad that after Christmas she is not going to be a rainfall child so can you stop Mr. Wilson from trying to do that thank you for all your help from K and A.

Professor Plant: Hi K and A. I’m glad to hear that you are enjoying the project! Please thank the rainfall child for all her hard work.

The Met Office have a website where people can share readings they’ve taken: http://wow.metoffice.gov.uk/ Maybe Mr. Wilson would be able to help her the first few times she enters data!

Coppull Parish Primary School: We had a mini disaster this week. The folder with results in was left out overnight in the rain. Although every page was completely sodden, and the file had to be binned. The relevant information was rescued by a group of y5 children including R, M and L.

Professor Plant: Hi Coppull Parish, I’m sorry to hear you’ve had trouble! I’m glad you managed to rescue your readings, well done all!
