The Frog Life Cycle

🧪Lab Brief #6

Life Cycles.

🎯 Your mission

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

⚡ The twist

Living things break the rules of non-living things — find the rule they break.

🤯

Mind = Blown

🌳 Trees can talk to each other through underground fungus networks.

🔮

Make a hypothesis first

Predict: what will happen to the plant if you change the water?

What You'll Learn

The life cycle of a frog includes egg, tadpole, tadpole with legs, froglet, and adult frog. This process of metamorphosis takes several weeks to months depending on the species.

Key Words

Tap a word to see its definition.

Materials Needed

  • soil
  • water

Safety First

  • Wash your hands thoroughly afterwards and keep the material away from your face.
  • Mop up spills straight away so nobody slips, and keep liquids away from sockets.
  • Check glassware for chips before use and carry it with both hands.

Steps

Step 1Read

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

Step 2Do

Build a model ecosystem in a jar using soil, small plants, and water. Seal it and observe how the water cycle works inside it for one week.

Step 3Observe

Compare the before and after states.

Step 4Record

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