8th Grade


The Eighth Grade Physical Science program takes students on a journey into the world of actions, reactions, force and motion - the world of Chemistry and Physics.

The primary goal is to spark students’ natural curiosity about the world around them and compel them to ask questions, conduct independent investigations, and seek unique solutions as they explore matter, chemical reactions, and the laws of physics. Throughout this course, students use evidence to support claims, evaluate data, and draw logical conclusions.

Hands-on class activities are uniquely developed to explore the scientific method, design thinking/engineering design process, matter, atomic structure, the periodic table of elements, chemical reactions, force, motion (including Newton’s Laws of Motion), and amusement park physics. We use a variety of resources, including the Discovery Education Science Techbook, as well as various technology applications including (but not limited to) Quizlet, Sutori, Socrative, and Flipgrid video, allowing students to demonstrate mastery of key course concepts in differentiated ways.
