We have been germinating cress seeds for the last week to see which conditions are the best for growing plants.
We thought they would need light and water so we have kept them as damp as we can and placed them in various different places over every evening.
Here are our results…

Which cress tray do you think has grown the most and why?
Which cress tray do you think has grown the least and why?
Are there any results that you found surprising?
If you were going to do this experiment again, what would you change?
