A plant is a living thing that often has roots, stem and leaves

We get light from the Sun so that we can see

To sit in the shade is to be in shelter from the light of the Sun

When we compare, we look at what is the same and what is different about at least two things

We record in science to keep information so that it can be looked at again

Plants without light

Science

In this Growing plants unit, pupils learnt that plants need water, light and a suitable temperature to grow and stay healthy. In the What plants do and what they need unit, they will build on this knowledge to learn that there are further requirements for life and growth and these vary from plant to plant

In the Identifying plants and their basic parts unit, pupils learnt to identify and name a variety of common wild and garden plants. In this Growing plants unit, pupils will build on this knowledge to observe and describe how seeds and bulbs grow into mature plants

This unit covers observing and describing how seeds and bulbs grow into mature plants, and understanding how water, light, and temperature affect plant growth and health. It involves performing simple tests, using observations to answer questions, and gathering data to explore plant needs.
