Helo Cyfeillion y Gwanwyn,

Diolch am eich gwaith caled ar y prosiect Bylbiau'r Gwanwyn i Ysgolion.

Plîs gwiriwch eich cofnodion data a chofnodion blodau'r wythnos hon er mwyn sicrhau bod nhw i gyd yn gywir ac yn gyflawn. Byddaf yn dadansoddi'r canlyniadau dros y gwyliau a chyhoeddi'r enillwyr a gwobrau ar 28 Ebrill. Bydd y tystysgrifau a gwobrau eu hanfon allan erbyn 15 o Fai. Bydd yr adroddiad yn cael ei anfon allan yr wythnos o 15 Fai.

Bydd pob ysgol hefo cofnodion tywydd a chofnodion blodau llawn, hefo cyfle o ennill taith natur ar gyfer eu dosbarth. Yn flaenorol mae'r enillwyr ar gyfer Lloegr, Yr Alban a Chymru wedi ei phigo o het!

Bydd ysgolion hefo cofnodion data uchel yn ennill hadau.

Bydd pob ysgol sydd yn rhannu ei chofnodion tywydd a chofnodion blodau ar wefan Amgueddfa Cymru yn ennill tystysgrif a phensil Gwyddonydd Gwych.

Mae ceisiadau ar gyfer flwyddyn nesaf yn awr ar agor! Plîs darllenwch y ffurflen yn ofalus.

Mae'r Ymddiriedolaeth Edina yn agor eu ceisiadau i ysgolion yn Rhondda Cynon Taf, Merthyr Tudful a Chonwy. Os yw eich ysgol o un òr ardaloedd hyn a hoffech gymryd rhan yn y prosiect Estyniad Edina yna plîs darllenwch y manylion yma. 

Diolch am eich gwaith caled Gyfeillion y Gwanwyn!

Carnbroe Primary School: It has been mixed weather this week sometimes cold but mostly we can feel it becoming warmer. All our daffodils finally flowered. Some children were disappointed because their crocus did not flower. We are taking our plants home with us. Have a good Easter and thank you for including us in your project.

Carnbroe Primary School: We had mixed weather last week and many of our daffodils have not flowered, yet! It snowed on Tuesday and we sent Professor Bulb photographs of our daffodils and crocus in the snow. By lunchtime the sun was out and had evaporated all the snow. We decided these flowers must be really hardy to survive in the cold.

Stanford in the Vale Primary School: It's been a cold windy week! We cannot believe spring is coming .The clocks go forward this week, looking forward to lighter evenings.

Broad Haven Primary School: The weather is getting better we have been to our beach to do a marine litter pick this week. We have tidied our garden ready to plant vegetables.

Tonyrefail Primary School: My daffodil grew taller than I thought.

Ysgol Deganwy: All of the plants are fully grown.

Helo Cyfeillion y Gwanwyn,

Mae llwyth o gofnodion blodau wedi ei chofnodi i’r wefan! Mae’r Gwanwyn yn wir wedi cyrraedd.

Mae’r canlyniadau hyd yn hun yn dangos diwrnod blodeuo cyfartalog o 3 Mawrth i'r Crocws a 8 Mawrth i’r Cennin Pedr.

Y dyddiau blodeuo cyfartalog ar gyfer blwyddyn ddiwethaf oedd 10 Mawrth i’r Crocws a 15 Mawrth i’r Cennin Pedr. Felly, mae’r cofnodion blodau hyd yn hyn yn dangos bod ein planhigion wedi blodeuo yn gynharach eleni!

Mae’r graffiau yn dangos sut mae’r canlyniadau hyd yn hyn ar gyfer tymheredd, glawiad ac oriau haul yn cymharu hefo ganlyniadau diwethaf. Mae'r graffiau yn dangos bod y tymheredd yn is na blwyddyn ddiwethaf i'r cyfnod o Hydref i Ionawr, ond yn uchaf ar gyfer mis Chwefror. Rydym hefyd yn weld bod y glawiad misol yn llawer llai na diwethaf, ond oedd oriau haul yn uchaf o Hydref i Ionawr. Mae’n debygol bod mis Chwefror cynnes ac oriau haul uchel wedi arwain ar ein planhigion i flodeuo yn gynharach blwyddyn yma.

Diolch am eich sylwadau Cyfeillion y Gwanwyn. Rwy’n falch i glywed rydych yn mwynhau’r prosiect. Cadwch ati gyda'r gwaith called!

Barmston Village Primary School: My daffodil is smaller than some others but I think my sign might have been in the way of the sun getting to the plant.

Barmston Village Primary School: We've noticed the crocuses have a different flower to the ones we planted in our village last year. Your crocuses have smaller pointier leaves than ours.

Barmston Village Primary School: My daffodil is only small and my crocus didn't grow. I wonder if I didn't plant my correctly.

Ellel St John's CE Primary School: We had 15 crocus' were open on Wednesday but when we checked on Friday there were 27 crocus'.

Broad Haven Primary School: Yes ours flowered first. A purple crocus.

Ysgol Deganwy: all of the flowers have budded.

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.

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.

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. 

Mae’r tudalennau addysg newydd yn cynnwys adnoddau sy’n cefnogi'r cwricwlwm Cymraeg. Mae’n darparu cymorth i athrawon ar sut i ddefnyddio’r wefan i fodloni'r Fframwaith Cymhwysedd Digidol. Mae’n cynnwys tudalennau ar metadata, hawlfraint a’r Fframwaith Cymhwysedd Digidol. Gallwch ddefnyddio’r wefan mewn ffurfiau gwahanol, ac mae hyd yn oed camau bach ar y safle yn profi sgiliau digidol. Mae’r casgliad yn anferth, hefo eitemau mewn ffurfiau gwahanol, fel lluniau, ffilm a sŵn. Mae hyn yn golygu bod y cynnwys yn ddiddorol, ac yn hawdd ei ddefnyddio.

Mae cyfranwyr i’r safle yn amrywio o amgueddfeydd ac archifau yn rhannu eu casgliadau digidol, i unigolion yn rhannu hanes teulu ac ysgolion yn rhannu gwaith dosbarth.

Mae’r wefan yn adnodd ardderchog i ysgolion, sy’n cefnogi nifer o brosiectau yn y dosbarth.

Dyma rhai syniadau ar sut i ddefnyddio’r wefan i ddatblygu sgiliau digidol:

• Defnyddiwch y safle i wneud gwaith ymchwil.
• Creu proffil i ddangos eich gwaith dosbarth, trwy greu rhestrau, rhannu eitemau a chreu casgliadau, straeon a llwybrau.
• Rhannwch adnoddau eich hun
• Ymchwiliwch y tudalennau addysg i ddarganfod adnoddau addysg ddiddorol a gwahanol i datblygu sgiliau digidol.

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!

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.
