In Grade 8, biology is only one part of the science  because Grade 8 science includes physics, biology, and chemistry. After we have our final test for the unit, we move on to the next unit. In the biology section, we mostly learning about cells. Cells are an important topic for science since many cells create living thing. We also did a lab activity where we can use microscopes to observe different types of cells. During the lab, we looked at our own skin cells and compared them to onion cells, it helped us  find out what is the different cells, after we look at the cells we can see the similar and the different in human and plant cells.
