Tunneling Worms

(Beaver, PA, USA)

A science observation activity in a jar:




Materials

peanut butter jar - empty and clean
dirt or compost (moist, not wet)
sand (slightly damp)
cornmeal
red wriggle worms (from bait shop)
black construction paper and tape

Instructions

1. Punch holes in the lids of the jar or use gauze and rubberbands to cover the opening.

2. Alternate layers of dirt and sand to form layers 1/2 to 1 inch thick.

3. Put worms on top and close jar. 4-5 worms

4. Cover outside tightly with black or brown construction paper. This step is very important - you want the worms to tunnel along the outside of the jar. If the jar is not covered they will stay in the middle.

5. The cornmeal may be sprinkled on top of the dirt for food (not necessary if you use compost or put some crumbled dry leaves in).

6. Check for tunnels every day and recover the jars.

7. Release the worms in someone's garden.
