Science KS1 / KS2: The life cycle of a frog and a sunflower

Science monkey superhero Dr Brain and a team of young scientists discuss all the things we associate with spring and summer.

They start by looking at the life cycle of frogs in spring-time, that begin life as thousands of tiny frog eggs known as frogspawn.

The team look closely at how each egg can turn into a tadpole, before growing little legs and arms and finally becoming a fully grown frog.

Dr Brain then moves on to the summer, and looks at how a sunflower develops from a tiny seed to a tall, beautiful flower, thanks to the process of photosynthesis, which turns sunlight, heat and water into food.

This clip is from the series Ultimate Brain: Mad Lab.

Teacher Notes

Pupils could use the clip to draw a diagram of the different stages of the life cycle of a frog.

They could then look closer at the animal at each stage and describe how it looks and changes over time.

Curriculum Notes

These films are suitable for teaching Science at Key Stage 1 and 2 in England, Wales and Northern Ireland, and 1st and 2nd Level in Scotland.
