After about a week, take a peek inside the jar by removing the construction paper. See what the worms have been doing! Every week, add a little bit of water to the jar to keep the soil moist. Put the paper back on the jar to keep it dark. Every six weeks, add a teaspoon of oatmeal for the worms to eat.
If you would like, you can move your worm farm outside by putting the worms in a garden.
