Introduction

Supercress!

You are in the supermarket with Mum and Dad doing some shopping. Mum wants to choose the best quality food for your family. She is looking for some cress to make a salad for dinner, but which sort does she choose? One of the boxes of cress is labelled 'organic'. Is that better quality than the other types of cress? Is that the one she should buy? She wants you to help her with this decision.

Which is best?

This one . . .

You can see how difficult it is for Mum and Dad to decide.

Perhaps you can help them.
