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.
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.
- Stick 3-4 toothpicks into a potato or sweet potato (they make for prettier plants).
- Put the potato into a glass jar. The toothpicks should hold the potato a few inches away from the bottom of the jar.
- Add enough water to the jar so that the bottom of the potato sits fully in the water.
- Place the jar on a sunny windowsill.
- Check the jar every day, adding water to keep the bottom of the potato wet.
- 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!
