Look at these two plants. One is green and strong. The other is pale and long. Why do you think one grew well and the other did not? What do plants need?

Let's name the plant parts we will watch. Drag each label to the right place. Roots take in water. The stem holds the plant up. Leaves catch light. Which part takes in water from the soil?

We will ask one class question about what plants need. Help choose: light or water. First we will write the two ways we will look after the pots on the board (for example one pot in the light and one in the dark, or one with water and one without). Then say what you think will happen to each pot, and why.

In pairs or small groups of three, plant the seeds in two clear cups. Use damp compost or cotton wool in both cups the same way. Label both cups: one Light and one Dark (or one Water and one No water), and add your group name. Place them where we agreed. Handle the compost gently and wash hands when you finish.

Your teacher will hand you an Investigation Journal page. First, draw how each pot looks today. Then you may say or write one short prediction using: I think the … pot will … because …. Drawing is enough; your teacher can help write a sentence if you need it. This is the page we will add to each week as we watch the plants.
