Cafodd blant blwyddyn 5 hwyl yn gario allan arbrawf teg i weld os ydy ‘huddle’ pengwiniaid yn helpu lleihau colled tymheredd. Mesurodd y plant y gwres a gollwyd dros hanner awr pan roddwyd dŵr poeth mewn un tiwb profi ac yna ei gymharu â ‘huddle’ o 7 tiwb profi a ‘huddle’ o 19 tiwb profi. Profodd y canlyniadau fod y ‘huddle’ yn lleihau colled tymheredd.

Year 5 children had fun carrying out an experiment to see if the penguin ‘huddle’ really does help prevent heat loss. The children measured the heat loss over half an hour when hot water was placed in a single test tube and then compared it to a huddle of 7 test tubes and a huddle of 19 test tubes. The results proved that the ‘huddle’ does prevent heat loss.
