Science Experiment
While being at Bamfield, we looked at many interesting things, but one particular part of the trip made me very interested. On Tuesday, October 6, right after breakfast, we went into the Whale Lab to study invertebrate diversity. This really was cool for me because we humans would not be able to walk if we don’t have our spine. How do these animals walk? An animal, which was really cool, was the hermit crab. These crab find snails shells to live in. Another reason was because I really like Spongebob and Mr. Krabs is a hermit crab. A have created an experiment to test on these awesome animals. Question: How long will it take for a hermit crab to find a shell and crawl in it, if the shell is 10 cm away from the crab in the start? Hypothesis: I feel this crab will be able to do this rather quickly so I believe he/she will be able to do it in under a minute. We watched a video where two hermit crabs were fighting for a shell. They were really fast getting into the shell. Materials:
Procedure: 1. Take a regular looking hermit crab and take it out of its shell 2. Measure where to put the items 3. I will start the timer 4. After doing this once I will wait a day so the hermit crab is fully rested and do it again. To get very detailed information I am going to do it for 3 days. Independent Variable - The crab Dependent Variable - How far the shell is Safety - For the hermit crab’s safety you need to treat it with gentle care so it does not get hurt. Is it ethical? Yes, this experiment is totally ethical. I am not doing anything that will affect the crab in the future or even harming it.
