In Segment A of Science 8, students will study scientific method and produce an actual experiment. They will also identify how human actions can affect a system. Students will learn about DNA, how it is passed on, how it changes over time, and how we can use DNA to classify organisms. They will also learn about the science of soils and agriculture. Other topics addressed include the forces that are shaping and reshaping the earth’s surface, including the effect of earthquakes and volcanoes. Students will also classify fossils and the geologic time scale.

Segment B of Science 8 will address the subject of matter. Topics include the structure of the atom, the Periodic Table of Elements, and will involve writing chemical equations and balancing chemical reactions. Students will be learning about energy in its many different forms. Conservation of energy will tie all lesson concepts together. Students will explore both current and static electricity, looking at various types of circuits and methods of generating electricity. Finally, students will learn about the concepts of motion and force and explore Newton’s three laws, looking at how they influence movement in our world.
