Mind = Blown

🔬 The more you look, the more nature shows you.

🔮

Make a hypothesis first

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

What You'll Learn

Seeds contain a tiny plant embryo and a food supply. When conditions are right—enough water, warmth, and oxygen—the seed germinates and a new plant begins to grow.

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

Look for patterns in your observations.

Step 4Record

Make a graph or chart showing your results.
