Here he is with some of the seeds:
The class split into groups to plant the seeds:
Two sets of seeds were planted: the seeds from space and some ordinary seeds from a garden centre.
The seeds were labelled in 2 sets, red and blue, and numbered from 1 to 100. However, we don't know which are space seeds and which aren't! We'll watch carefully to see if there are differences in the way the plants grow.
