Eighth Grade, Physics Lesson Plans (28 results)

Physics is the study of matter — what is it made of? How does it behave? What laws or equations describe it? From subatomic particles, to the Big Bang, modern physicists study matter at a tremendous range of scales. There's a whole lot of interesting physics at the human scale, too.

Study Kinetic Energy with a Rube Goldberg Machine

Lesson Plan Grade: 6th-8th

1 review

Rube Goldberg machines—machines that complete a simple task in a convoluted way—are intriguing, artistic, and fun! In this lesson, students will design and build such a machine themselves and use the concept of kinetic energy in the process. Before students start designing, they will do an experiment that explores how kinetic energy depends on the mass and the speed of the moving object. With a clear understanding of this concept, students then tackle the engineering design… Read more

NGSS Performance Expectations:

MS-PS3-1. Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

Solve a Mirror Maze Challenge with the Law of Reflection

Lesson Plan Grade: 6th-8th

10 reviews

When light interacts with an object, it can be absorbed, transmitted, or reflected. This lesson focuses on materials that reflect light. Specifically, students will use mirrors and flashlights to investigate how light is reflected from a surface. By doing that, they will discover that when a light ray hits a reflective surface, its angle of incidence is equal to the angle of reflection, which is stated by the law of reflection. Students will then use their gained knowledge in a mirror maze… Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
MS-ETS1-4. Develop a model to generate data for the iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Build a Recycling-Sorting Machine

Lesson Plan Grade: 6th-8th

5 reviews

In this lesson plan, your students will build their own recycling sorting machines that use various methods, like magnets or puffs of air, to separate shreds of paper from paper clips. This lesson is inspired by the real-world engineering challenge of separating various materials, like paper, plastic, and metals, that get combined in single-stream recycling programs. Read more

NGSS Performance Expectations:

MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
MS-PS2-5. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Design a Paper Airplane Launcher

Lesson Plan Grade: 6th-8th

5 reviews

Aircraft carriers are much shorter than a typical airport runway. How do airplanes manage to gain enough speed for takeoff over such a short distance? A catapult gives them an extra boost! In this lesson, your students will practice engineering design as they build their own paper airplane launchers, while learning about kinetic and potential energy. Read more

Modeling Gravity

Lesson Plan Grade: 6th-8th

2 reviews

Why can we feel gravity pull us down towards the Earth, but not sideways towards other big objects like buildings? Why do the planets in our solar system orbit the sun instead of flying off into space? In this lesson plan your students will develop a model for gravity and use it to explore answers to these questions. Read more

NGSS Performance Expectations:

MS-PS2-4. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

Push Harder — Newton's Second Law

Lesson Plan Grade: 6th-8th

Don't just teach your students about Newton's laws of motion using diagrams in a textbook—try something hands-on! In this project, students will build their own cars using craft materials and explore the relationship between force, mass, and acceleration.
