This is one of the YouTube clips I used in my unit plan. It offers an alternative to, or supplements having the children grow their own seed which is a common activity in primary school.
Another YouTube clip that I used in my unit plan. I have seen this clip used in the classroom to a great response by the students and the supervising teacher. It's a fun and memorable way to learn the water cycle.
YouTube provides an infinite nuber of clips that can be used to engage the students, further their understanding or even as an assesssment tool.
