Science with Ollie

Up or Down?

Two ways seeds sprout! Ollie plants a bean and a pea, then we peek under the ground. The bean pulls its seed leaves up into the sunshine. The pea keeps its seed leaves down in the soil.

The big idea

Seed leaves go up, or stay down

Every seed has a baby plant inside and seed leaves full of food. Their big name is cotyledons (cot-ee-lee-dons). First the root grows down. Then comes the surprise:

Sprouts UP

The stem bends like a hook and pulls the seed leaves up out of the soil. They open in the sunshine.

Beans and sunflowers

Stays DOWN

The seed leaves stay under the ground. Only the green shoot grows up, with brand new leaves.

Peas and corn

A bean and a pea in a jar

Grow them side by side and see the two ways for yourself. Roots show up in a few days, shoots in about a week.

  1. Towel in a jar

    Press a folded paper towel around the inside of a clear jar.

  2. Keep it damp

    Add a little water to the bottom so the towel stays wet, not flooded.

  3. Bean and pea

    Slide a dry bean and a dry pea between the towel and the glass.

  4. Up or down?

    Look every day. Which one lifts its seed leaves up? Draw it in your workbook!

👋 Ask a grown-up to help. Dry seeds are a choking risk for little ones, and raw beans are not for eating.
