1 Plants are living things

Seven rules: alive or not alive?

Each day you see animals and plants that are alive.

You also see materials like wood and straw that were

once part of a living thing. Other materials, like sand,

have never been alive.

Try using these seven rules to see if something is alive.
Living things do all seven!

Alive or not?

You will need: a plant, a bare branch, a plastic plant, a block of
wood, a piece of rock

With a friend talk about these things. Describe each one.

What is it made of? Where did it come from?
Is it alive or not alive? Use the seven rules to help you.
