A whole plant sleeps inside a tiny seed. All you have to do is wake it up!
What you need
A dried bean, cotton wool, a glass jar, water.
The steps
1️⃣ Wet the cotton wool and press the bean against the side of the jar.
2️⃣ Place the jar near a window.
3️⃣ Add a little water every day.
4️⃣ Draw what you see every two days.
What will happen?
The seed swells, the root emerges first, then the stem grows towards the light, and the first leaves unfold.
🤯 Did you know?
A bean seed can wait for months, or even years, before germinating. It knows how to wait for the right conditions: water, warmth, and off it goes!
Test, compare, predict
Plant two seeds: one in the sun, the other in a cupboard. Which one grows faster? Which one is greener? Write down your predictions before you look.
🔎 Observe the tiny root hairs with a magnifying glass or a pocket microscope: they drink up water like mini straws!
