Gloves may be replaced with common household style gloves.
If the gloves stick to hands, sprinkle the insides of the gloves with a very
light coating of baby powder (corn starch).
Suggested Activities
The Hands-On Discovery Lab is perfect for conducting big science without
making a big mess. Plug in the side caps and use the lab as an observation
station.
Notes: You may detach the gloves and use your bare hands while performing
activities.
Watch worms wriggle their magic and turn fruit and vegetable scraps into
great potting soil for house plants!
What you need to supply:
1 Dozen red worms (Do not use night crawlers or other earthworms.
Smaller red worms are best suited for the size of the lab and can be found
at most bait and tackle shops or pet stores).
Newspaper (Use black and white print. Do not use colored ink pages).
Aluminum foil
Gardening soil (Do not use “potting soil”).
Water (A spray bottle or small watering can will do).
(2) Crushed, boiled eggshells (Do not use raw eggshells!)
Food scraps (See details in the “Feeding Your Worms” section).
What to do:
1. Read all of these instructions first!
2. Place some moist (not wet) shredded newspaper on the bottom of the
clean lab tub.
3. Add several handfuls of garden soil (not potting soil) with a couple of
crushed eggshells mixed in. Take care not to overfill the soil above the fill
line.
4. Moisture helps worms breathe, but too much water will drown them.
Keep the soil mixture damp but not wet or muddy. You can always spray a
little more water in daily to keep it moist.
5. Worms like the dark. To cover the dirt, wrap up the sides of the Discovery
Lab halfway in aluminum foil. You’ll also want to store the lab in a dark
place, such as a garage or basement. Carefully unwrap the foil if you are
going to observe the worms for a while. Always replace the foil when
finished.
6. Place a few more scraps of damp, shredded newspaper and eggshell on
top of the soil. Do not pack everything down—leave it loose.
7. Add your worms to the soil. Don’t poke them too much. Be gentle and
