Sprouting seeds: what seeds need — Science experiments for kids

You need: moong seeds, cotton wool, two small bowls, water and a few days. What happens: the seeds on wet cotton swell and a tiny root pokes out in a day or two; the seeds on dry cotton do not change. Why: a seed needs water, air and warmth to start growing (germination). It carries its own food store, so it needs no soil to sprout. Seeds even sprout in the dark, but their leaves stay pale yellow without light.

What you do

Water, air, warmth — “a seed needs water, air and warmth to sprout — not soil or light”

  1. 1. Put cotton wool in two bowls; wet one and leave the other dry.
  2. 2. Place 10 moong seeds on each.
  3. 3. Keep both bowls in the same warm place and keep the wet cotton damp.
  4. 4. Count the sprouted seeds every day, and wash your hands.

Use it for: Class 3–6 EVS and science lessons on seeds and plants; a classic science experiment with explanation.

Worked example: 🌱 Seeds need water, air and ___ to sprout. → warmth

  1. A seed needs three things to wake up and grow.
  2. They are water, air and warmth.

Check: Seeds on wet cotton in the freezer do not sprout — too cold ✓
