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,
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.

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 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 31st 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!
