Zoology Science Fair Project

Light and Crayfish

Medium
Light and Crayfish | Science Fair Projects | STEM Projects
We're going to find out if Crayfish are attracted to light or repelled by it. We'll put them in an aquarium and observe them for 30 minutes to see which side they choose.

Hypothesis

The hypothesis is that the majority of the Crayfish will move toward the darkness, and reject the bright light.

Method & Materials

You will need to collect materials, divide an aquarium into two parts, cover the bottom of each area with rocks and water, cover the top of one area with thick, black paper, place a 60-watt light bulb in a reading light, and place the crayfish in one side.
You will need 7 Northern Crayfish, an aquarium, rocks, water, a foam divider, and a 60-watt light bulb.

Results

The results showed that the majority of the Crayfish ended in the dark area, regardless of where they were placed in the beginning of the experiment. This indicates that the hypothesis should be accepted.

Why do this project?

This science project is interesting because it helps us understand how Crayfish react to light, which can be useful for people who raise or sell Crayfish.

Also Consider

Variations to consider include changing the distance of the light from the Crayfish, or changing the intensity of the light.
