What do plants need to grow?

Find out what conditions plants need to germinate and grow, then plant seeds knowing what they need for successful growth.

Look at the results of what seeds need to germinate and how gravity affects seed germination, and summarize what plants need to germinate and grow: the seed needs water, air and darkness to germinate. Once the leaves are formed the plant needs water, air and light. Seeds send their roots down and their shoots up through responding to gravity.

Students plant seeds in soil. They can look after them knowing that they need water to grow. They have darkness as they are under the soil. They get air through the spaces in the soil.

Students dissect a seed to see where the plant comes from.
