Potato Science!

Hi Everyone! Happy Saturday! One last potato-themed post: Today we have a couple of science experiments you can check out with your kids!

Potato Battery: Ever wondered how to make a potato clock? You can follow the instructions here:


You will need copper wires with alligator clips, a galvanized nail, and a battery powered clock.

Or, you for convenience, you can purchase the “kit” we have seen at Modular or buecher.de (Probably also on Amazon) https://www.buecher.de/shop/naturwissenschaften–technik/green-science-kartoffeluhr-experimentierkasten/karten–brett-oder-wuerfelspiel/products_products/detail/prod_id/56525702/

The Sciencing page also has 2 other experiments you can do with potatoes: a smell and taste test and an experiment in planting.

Potato Plant

You can also follow these instructions for sprouting your own potato plant from St. Peter Food Coop in Minnesota (https://stpeterfood.coop/crafts-with-potatoes/):

Let your kids monitor the progress and learn more about how food grows. Try an organic and traditional potato simultaneously to see if there are any differences.

  1. Stick 3-4 toothpicks into a potato or sweet potato (they make for prettier plants).
  2. Put the  potato into a glass jar. The toothpicks should hold the potato a few inches away from the bottom of the jar.
  3. Add enough water to the jar so that the bottom of the potato sits fully in the water.
  4. Place the jar on a sunny windowsill.
  5. Check the jar every day, adding water to keep the bottom of the potato wet.
  6. You will start to see sprouts forming on the bottom of the potato (roots beginning to emerge). In about a week, you will see small leaves growing from the top. Keep the water level the same in the jar, so the sweet potato bottom stays wet. After 2-3 weeks, you will see several long vines with green leaves. You can continue watering your potato as usual in the jar or transplant it into a pot with soil. Your sweet potato will continue growing into a green, leafy houseplant!
