Worm Farm
-You will need:
-Empty glass jar (mayonnaise works great!)
-Dark paper
-Yarn
-Soil
-Worms


You will want prepare the project for the children. Start by cleaning out an empty mayonnaise jar (one for each child) and allowing them to dry, make sure to remove the labels. You will need 3-4 worms per farm. You can either buy them or dig them up your self. If you are going to need a lot, I would just buy them.

Place a container in the middle of the table filled half way with soil add a couple of sandbox shovels for the kids to scoop the dirt into their jars with. You will want to soil to be moist, but not so wet that the worms will drown. It is easier to either pre measure the water or just mix it into the dirt before.

The kids will need to fill the jar 3/4 of the way full of soil. To provide a clear stopping point for the kids try wrapping electrical tape around the jar.

Next have the preschoolers add 3-4 worms to the dirt. If you have a child who is interested but does not want to touch the worms put the worms in a small cup for the child to just pour into the jar.

Next put a few old damp leaves or a worm smoothie on top of the dirt, make sure to cover the dirt completely. To make a worm smoothie put leaves, vegetable peelings and eggshells into a blender and puree.

Wrap the dark paper around the outside of the jar. Use the yarn to hold the paper on. Preschoolers who have not mastered tying shoes will need help with this.

Set the worms aside, keeping out of direct sunlight. The worm farm will need some water every couple of days. Remember not to add to much water or the worms will drown. Make sure that you periodically add new leaves, grass clippings or worm smoothie to the top of the worm farm, so the worms will have food available whenever they get hungry.

After a week you can open the jar inside to a dimly lit room and take the paper off the jar and look at what the worms have done. Replace paper when finished. If properly cared for, you should be able to keep a worm farm going for quite some time.
