Our question is, "Will Dragonfly larvae eat more minnows in light or in darkness?"
H1 Dragonfly larva will eat minnows most often in constant light.
H2 Dragonfly larva will eat minnows most often without constant light.
H0 Dragonfly larva will not be influenced by constant light or darkness when eating minnows.
We set up three aquariums with dragonfly larva in each. One aquarium had lights on constantly, one was covered with black construction paper and one was kept as a control and was exposed to a natural cycle of daylight and night time. Each aquarium contained the same number of dragonfly larvae and minnows. The minnows were counted after 24 hours on four separate observations.

Our question is, "What are Woolly Bear Caterpillars and what do they turn in to?
We collected and observed 21 Woolly Bear Caterpillars. Through internet and library research we learned how to care for them and how to recreate their natural habitat. The caterpillars are now overwintering outside our classroom window. It is our goal to bring them back into the classroom in the spring and observe them completing their lifecyle into Tiger moths.
