Before you start: write down what you think will happen, and why.

What You'll Learn

Animals can be classified as herbivores (plant eaters), carnivores (meat eaters), or omnivores (eating both plants and animals). Their teeth and digestive systems are adapted to their diet.

Key Words

Tap a word to see its definition.

Materials Needed

  • water

Safety First

  • Never look directly at the Sun or into a laser, even briefly.
  • Mop up spills straight away so nobody slips, and keep liquids away from sockets.

Steps

Step 1Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2Do

Design a controlled experiment: grow plants under different light conditions (full sun, partial shade, no light). Water equally and measure growth daily for one week.

Step 3Observe

Watch carefully for any changes and note the time.

Step 4Record

Create a data table to organize your measurements.
