My favorite subjects in school are Chemistry, Biology, and Math. They are really fun and engaging. When I am learning these subjects, it is like I am looking deeper into the world. It is amazing to know that this world is not as simple as it looks. When we peer deeper, we will find something amazing that we may not expect. For example, when I learn Biology, I found out that the human body is very complex. Groups of organs work as a system, each with their own function, resulting in a healthy body. The role of cells is to build up tissues, and tissues build up organs, while organs build up the body, and we can finally do activities.
