We have put cress seeds on damp cotton wool in little dishes.
We put one of these dishes in a closed cardboard box, one in a cardboard box with a hole cut in the top of the box and one in a cardboard box with a hole cut in the side of the box. We have been predicting which set of seeds will grow best and whether there will be any difference in the way all of these seeds will grow.
We'll let you know in a week or so.
