This is a very fun experiment to do with the kids to see if it matters what soil your plants grow in and a great way to upcycle your used coffee capsules. In this experiment we will see what happens when barley seeds are growing in coffee, in potting soil and in a mixture of that.
You will need:
- 9 used coffee capsules (at least).
- Barley seeds or any other quick growing, low maintenance seeds.
- A cup of potting soil.
- Mixing bowl or tub.
- Old spoon.
- Water.
- Tray.
Method:
- Peel the foil off the capsules and throw in the recycling.
-
Put the coffee from the capsule in the mixing bowl
-
Rinse the capsules once emptied.
-
Add a little bit of water to the coffee in the mixing bowl. Be careful not to add too much.
-
Fill three capsules about 2/3 with coffee.
-
Sprinkle a few seeds on the coffee.
-
Cover them with more coffee to the edge.
-
Repeat the same process, using potting soil in the next three capsules.
-
Lastly, mix equal parts coffee and potting soil for your last three capsules.
I had to wait a week but after that I could sure see the difference. Turns out it’s not just us humans who love a good cup of coffee!
If you do this with your kids, don’t spoil the expected outcome.
