British astronaut Tim Peake has beamed a video message to thousands of schools asking them to grow seeds that have journeyed through space.

The special rocket seeds will be sent back to earth and given to schools to grow and compare to seeds which have not been to space.

It is hoped the experiment will help reveal the effect of micro-gravity on seed growth.
