And then came the worm project. For the upcoming school science fair, Cassie has been raising Red Wiggler worms in the basement. These worms are raised for their ability to compost and can consume up to their entire body weight in organic compost every day. Cassie set out to determine which of four different diets would produce the most worms and the best soil quality. She has been carefully tending the worms since late December, keeping extensive records of the number of worms, soil quality, and the amount and type of food she fed the worms. Here's a brief excerpt from her research paper:
"My conclusion is that a mixed diet is best to increase the worm population and help keep the soil nutrients. The best diet for this situation is a mixed diet of vegetables or fruit, together with leaves. I also concluded that the fruit diet has the greatest impact on waste reduction. The Red Wigglers that I used for this experiment are used for their ability to compost. They can consume up to their entire body weight in organic compost every day. A healthy Red Wiggler population can double in 90 days. The larger a population, the more the worms can compost and the more waste they can reduce. My group of fruit-fed worms tripled its population in just 45 days. I'm glad I chose an experiment that can be applied to the real world. My conclusion helps because using worms to compost reduces waste. And, using worms to produce better soil is safer for people and animals than using chemical fertilizers. The knowledge of how to benefit the earth can help all people be green."
After I read Cassie's paper, my first thought was, "Wow. My Dad would sure be proud." And then a flood of memories hit me - my Dad's massive compost piles; the Spring gardening rituals; the worms that we raised in the basement when I was a kid;. Cassie's work truly manifests my Dad's love of nature. There will be some tangible memories that we cherish. But, Cassie's love of nature is a worthy legacy.
