Bacteria in science class

Today in science we first reviewed our homework. It was to write a conclusion about the tests we've been performing on bacteria. We each got into groups of two and looked at eachother's conclusions. After we told each other what we did right and what we did wrong, we revised it to make it even better. After that, we made observations in our notebook. The observations were based on a video we watched looking through the lenses of a super microscope. The microscope had a view point of bacteria reproducing very rapidly. We learned a new vocabulary word called binary fision. This is the process of bacteria reproducing by splitting into two. But before the bacteria split into two they had to grow to stay the same size. Below are the different pictures of what the bacteria looked like in the video we watched.

After watching the video, we shared and discussed the observations that we made from the video. Also, that's when we talked about binary fision and why the bacteria doubled themselves hundreds of times.
