Do plants need sunlight to grow?
1.2 Plants need energy from light
Use small green plants, like beans, for this investigation. 1 Describe what you will do to make this a fair test. Think about the number of plants you will need, the size of the plants and the growing conditions.
2 What do you predict will happen?
3 Observe the plants every day for at least one week. Measure the height of each plant. Describe the colour of the leaves. Record your observations here. Day 1 Plant A
