Semester Project Blog
Our semester project consisted of worms, a lot of food and patience!
In our semester project, Beth Peterson and myself learned that worms don’t like sugary foods. They enjoy eating healthy-like foods. (ex. strawberries-which happened to be the sample that won-,vegetables, fruits, etc.)
Materials: 10 oz. of each food, (bread, strawberries, chocolate, french fries, gummy worms, and soil.)
Our investigation began with a problem. After many bad ideas, we came to the conclusion that we wanted to “care” for worms!
Our problem: Which food is most favored by the worms?
Hypothesis: We think the worms will favor the soil more than any other food selection because the worms live in and around the soil.
The procedure for testing this hypothesis: 1) Measure 10 grams of each selected food
2) Disperse each food equally, giving each team of worms a different food choice.
3) Leave the food in the designated area and allow the worms access to the food.
4) Measure, the next day, the amount of food the worms have eaten, and record.
5) Continue measuring the mass and rate the worms eat the foods.
Conclusion:
Our experiment, though not the best idea, did not turn out how we expected. We assumed that, because worms live in and around soil, that they would be more prone to favoring soil. Gummy worms, french fries, bread, and chocolate, as well as soil were no competition for the strawberry. We assume that the reason they favored the strawberry is because it is a fruit and it has nutrients to provide the worm. Our hypothesis was wrong.
If we could change anything we would select healthier foods, and include ant repellent in the materials!!!!
