Do plants need light to grow?

We want to find out if plants really do need light to grow.

Before we planted our seeds we decided what we should do.

We thought we should try to grow one plant on the window sill where there is lots of light, and one plant in the cófra where it is dark all the time.

We predict that the plant (or plants) on the window sill will grow very well (if we remember to water them!) but the plants in the cófra won't grow at all.

We will check on them regularly to see what happens!

We can't wait to see what happens to all our cress seeds.

After 2 weeks:
