Well, I'll tell you about the 8th-grade science facts. In 8th grade, the type of science you learn about is physical science. Physical science is the study of nature and natural living such as chemistry, physics, astronomy, and natural objects. Us beautiful 8th-graders (haha) learn about the topics: scientific method, measurement, and state of matter. We get into more of simple machines during the end of the school year. To learn more about physical science talk to your 8th-grade physical science teacher and pay close attention in school!
