Science 3rd grade | UNIT 3: Living things 3.3 Movement and reproduction
All animals and plants move.
Plants move slightly towards the light.
They can also spread across areas as their roots systems grow.
Their seeds can also move.
Activity 3.3 (Make a model of the moving parts of your body)
You will need: a template of parts of the body - split pins
Cut out the parts of the body from the template.
Use split pins to join the parts together.
Reproduction
Living things reproduce so that new animals and plants can grow to become adults. Plants make seeds. Animals and birds lay eggs or have babies.
When animals reproduce they often make a special home for the young or the eggs. Some animals carry their young.
Some animals do not prepare a home. The offspring have to look after themselves.
Fish swim off into the sea without parents.
Caterpillars are left to look after themselves.
