Following our work on the weather and on Green Energy, Class 4 had a question to answer - What sort of blade would catch the wind the best on a wind turbine? After a lot of research, trial and error, our turbines were ready to be tested. We tested them by counting how many times the blades rotated in a minute, We used a fan to generate 'wind'. We were amazed by the results! The best one continued to rotate at quite a distance away from the fan!

Yn dilyn ein gwaith ar y tywydd ac ar Ynni Gwyrdd, roedd gan Dosbarth 4 gwestiwn i'w ateb - Pa fath o lafn byddai'n dal y gwynt orau ar dyrbin gwynt? Ar ol lot o waith ymchwil a trealu, roedd ein tyrbins yn barod. Penderfynom gyfri sawl gwaith oedd y llafnau yn cylchdroi mewn munud. Defnyddiom ffan i gynhyrchu 'gwynt'. Roeddym wedi dychryn efo'r canlyniadau! Roedd yr un gorau yn troi hyd yn oed pan oedd o'n bell o'r ffan!
