Organisms.

๐ŸŽฏ Your mission

Predict it first. Then prove yourself right (or wrong).

โšก The twist

Nature loves to surprise the careful watcher.

๐Ÿคฏ

Mind = Blown

๐Ÿ”ฌ The more you look, the more nature shows you.

๐Ÿ”ฎ

Make a hypothesis first

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

  • species
  • organism
  • habitat

Materials Needed

  • cups
  • water
  • plastic wrap

Safety First

  • Keep small objects away from young children.
  • Work in a well-ventilated area when using vinegar or other strong-smelling substances.

Steps

Step 1 โ€” Read

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

Step 2 โ€” Do

Dissect a flower (lily or tulip works well). Identify and label the sepals, petals, stamen, pistil, and ovary. Tape each part to paper.

Step 3 โ€” Observe

Compare the before and after states.

Step 4 โ€” Record

Write your conclusion: did the results match your hypothesis? What would you change next time?
