Snail Observation Lab


I was really excited when I knew that I was going to observe a snail in Biology lesson. I had never examined a snail before, so I was very happy when Mr. Olson told us that we were going to have a Snail Observation Lab.

We had to complete a set of questions for this snail observation. They included describing the snail, finding more about the snail's behaviour and its reactions to different substances. Besides observing, we also needed to find information in a reference book to answer the questions.

Although I was looking forward to the observation, I felt a little bit scared when I saw the snail. I tried to take it up and put it on the watching glass, but I was afraid that its shell would get off. Moreover, its slimy brown skin made me feel bad when I touched it. Finally, my partner and I removed it clumsily.

When we were observing the snail and writing down the answers, the snail kept crawling out of the watching glass and moved towards our paper. I nearly screamed out loud when it was on my paper.

We observed a lot of things from the snail. I had never noticed such things before, probably because I would not pick up a snail in a garden and observe it. I observed that the snail had tentacles and it had particular movements. It hates vinegar and opens its mouth when eating. I also got a lot of information from the reference book.

It was really fun to do all these observations. I really enjoyed that Biology lesson and I hope that I will have the opportunity to observe other things in the future.
