Science Fair Topics : Vermicomposting

If you are anything like me, you have not looked forward to the yearly science fair topics with your kiddos. That was until I decided, if I have to help, then we are going to pick topics that we both are interested in learning about. We are at least "active" participants, right?

Whether your child is in Kindergarten, 3rd grade or 8th grade: these hypothesis would work. You can make it as detailed or as simple as you need.

Here are some ideas for science fair projects involving worm composting.

1. Worm Castings vs. Chemical fertilizer: effect on growth rate(this one is a great way to incorporate plants into your project, we started from seeds with ours)

2. How much waste does a pound of worms consume per day/week/month/year?

3. Does density of food waste effect daily consumption by worms? (ie lettuce vs. carrots)

4. Do red worms prefer manure or yard waste?

5. What bedding is the best for red wiggler worms?

6. Do red worms prefer a wood bin or a plastic bin?

7. Do nightcrawlers or red wigglers compost more produce?

8. Which composts faster? A compost pile or worm bin?

9. Which nourishes plants more: worm tea or castings as a broadcast application?

10. Acidic foods vs non acidic foods (citrus/tomatoes vs melon/banana). Do worms prefer one food over other? Do they make better castings with a certain type food.

11. Peat Moss vs. coconut coir as worm bedding. Which one is more hydroponic? Which one do worms consume faster?

12. Will seeds germinate faster in worm castings or in store bought potting soil?

13. Do worms really prefer a dark environment? What do they do when they are exposed to light?

14. Can worms survive in water?

15. What breed of worm is best suited for your climate?

Can you think of any more ideas? I would love to post them here, email me if you have ideas to contribute.
