Academic Grade 8 Science

8th Grade Curriculum

Eighth Grade Science

All science students need to understand and apply the scientific method to scientific concepts and experiments.

The beginning of the school year begins with the scientific method and review of the measurement systems used in science.

Physics: Forces and Motion

Forces and Motion – What makes objects move the way they do?

Physics: Forces and Motion

Forces and Motion – What makes objects move the way they do?

8.1 - An object’s inertia causes it to continue moving the way it is moving unless it is acted upon by a force to change its motion.

  • The motion of an object can be described by its position, direction of motion and speed.
  • An unbalanced force acting on an object changes its speed and/or direction of motion.
  • Objects moving in circles must experience force acting toward the center.

C 22. Calculate the average speed of a moving object and illustrate the motion of objects in graphs of distance over time.

C 23. Describe the qualitative relationships among force, mass and changes in motion.

C 24. Describe the forces acting on an object moving in a circular path.

Genetics and Heredity

Heredity and Evolution – What processes are responsible for life’s unity and diversity?

8.2 - Reproduction is a characteristic of living systems and it is essential for the continuation of every species.

  • Heredity is the passage of genetic information from one generation to another.
  • Some of the characteristics of an organism are inherited and some result from interactions with the environment.

C 25. Explain the similarities and differences in cell division in somatic and germ cells.
C 26. Describe the structure and function of the male and female human reproductive systems, including the process of egg and sperm production.
C 27. Describe how genetic information is organized in genes on chromosomes, and explain sex determination in humans.


Earth in the Solar System – How does the position of Earth in the solar system affect conditions on our planet?

8.3 - The solar system is composed of planets and other objects that orbit the sun.

  • Gravity is the force that governs the motions of objects in the solar system.
  • The motion of the Earth and moon relative to the sun causes daily, monthly and yearly cycles on Earth.

C 28. Explain the effect of gravity on the orbital movement of planets in the solar system.
C 29. Explain how the regular motion and relative position of the sun, Earth and moon affect the seasons, phases of the moon and eclipses.

Science and Technology: Bridges

Science and Technology in Society – How do science and technology affect the quality of our lives?

8.4 - In the design of structures there is a need to consider factors such as function, materials, safety, cost and appearance.

  • Bridges can be designed in different ways to withstand certain loads and potentially destructive forces.

C 30. Explain how beam, truss and suspension bridges are designed to withstand the forces that act on them.
