Laws of Motion

6th - 9th

Do you need some new ideas for teaching Newton's Laws of Motion? This series of activities will spring your curriculum to life! Choose from five activities to demonstrate or have your science stars perform. As a result, they will have fully explored forces in action. You will also find five creative assessment suggestions that can be used as homework or follow-up discussion.

If You Force It, It Will Move

Ninth graders investigate and use Newton's laws of motion to describe and predict motions of common objects in controlled experiments (e.g., balls rolling, wood blocks sliding) and in real-world contexts (e.g., walking, rollerblading, braking).

Newton’s Laws of Motion Project

After a review of all three of Newton's laws, physical scientists complete a choice project. They can create a book in which they collect pictures where the laws of motion are depicted, produce a PowerPoint presentation, or produce a short film explaining each law. Completing the project can be fun, but presenting the same information in class repeatedly may not. Also, because of the amount of time required for these projects, you may want to assign them to be done at home.

The Physics of Bridges

Construction engineers research types of bridges online and diagram the forces exerted on each. The create different shaped trusses and test for strength. Finally, they will form teams and compete in "Physics Olympics: Bridge Building." This outstanding resource provides all of the lab sheets and terrific teacher's notes.

Lab: Kelper's Laws of Planetary Motion

High school astrophysicists perform the classic activity of using a loop of string and two push pins to draw ellipses and calculate eccentricity. They also answer questions and solve problems using Kepler's laws of planetary motion. The worksheet sends learners to consult a "Planet Data Table" in their notes, so you will need to provide individual planet orbit information. It also refers to a specific textbook for definitions. Perhaps your best use of this resource is to simply imitate it as you create your own with specific references to your own classroom materials.

If You Force It, It Will Move

Ninth graders examine science concepts and principles that predict physical events.  In this science lesson students investigate Newton's Law of Motion and predict motions of common objects. 


In this forces worksheet, young scholars read about force and acceleration. They complete a Venn Diagram to compare and contrast balanced and unbalanced forces, they answer questions about a diagram of a tug-a-war and the forces acting on each side of the rope and they answer 16 multiple choice questions about forces, Newton's Laws of Motion, velocity, speed and acceleration.

Newton's Laws

In this motion worksheet, young scholars read about the 3 laws of motion and then complete a graphic organizer describing the laws and giving an example for each one.

CPO Science - Foundations of Physics

An object in motion will remain in motion, and your physics learners will really get moving by viewing this PowerPoint! They examine each of Newton's laws of motion, learning about force, inertia, acceleration, and equilibrium. They are given practice calculating acceleration and force in different situations. Crisp, clear graphics provide visuals for understanding the direction of force. Except for chapter references throughout, this is a perfect presentation for your first-year physics class!

Newton's Second Law

Students examine how physical quantities and laws depend distance, mass and time. They examine the MKS system; meter, kilogram and second, for doing calculations.

Kelper's Three Laws

A flipped classroom lesson introduces astrophysics fanatics to Kepler's three laws of planetary motion. After reading about the laws of ellipses, equal areas, and harmonies, and also learning how Newton's gravitation concepts come into play, they answer nine questions as a review. When learners return to class after exploring this assignment, review the answers to the questions and then provide some problem solving practice.

Lesson Planet provides plans that are a snap to personalize or utilize as is. Providing rigor and relevance the lessons are an excellent resource. I highly recommend LP for both the new teacher and the well seasoned pedagogue.
