SCIENCE PRO

Design an experiment

to find out what kind of soil or plant food grows the most potatoes. For example, plant the same number of seed potatoes in the same sized bags. Then feed each bag with different fertilisers. Be sure to include one bag that has no fertiliser and don’t forget to label them! Weigh your crops after harvest to get your results. We’d love to hear how you get on.
