1. What science ideas did you learn?

This week I learned about the structures of bacteria and virises. We think that bacteria is living while virises aren't. We think bacteria is living because bacteria is made up of cells which is a characteristic of life. Bacteria also has DNA, which is another characteristic of life. We think that virises aren't living because they aren't able to reproduce. Also, they don't have any ribosomes so they don't have any energy organelles. Finally, virses aren't composed of cells.

2.How did you learn these ideas?

I learned these ideas by studying pictures of the structures of both a viris and bacteria. I looked at the labels of both and realized that the viris didn't have all the characteristics of life and the bacteria did. I also learned these ideas by having class discussions and hearing different people's thoughts and predictions.

3.Why is it important to know this idea?

It is important to know these ideas because it will help us with the experiments we do. For the experiments that we are making up, we have to know a lot about bacteria and viris because we have to be able to tell if something has bacteria or if it has a viris. We also have to know if the bacteria and virises are alive to be able to make an accurate hypothesis.
