Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

Experiment with the center of gravity by stacking blocks in a way that appears to defy its force. This is a fascinating demonstration that you can use when teaching about gravity, forces, or balance. 

Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

Define six common forces: propulsion, air resistance, water resistance, friction, gravity, and upthrust. A picture of a Smart Car is displayed with arrows showing all of the forces acting on it when it is motion. A picture of a rubber...

Host a design challenge of Olympic proportion! Junior engineers build their own bobsleds using simple materials. The activity focuses on kinetic and potential energy and how the center of mass affects motion on a downhill track....

Definitions of gravity and weight and the calculations involved with their manipulation are covered here. The equations and resource links will be valuable to show a physics class. Use it as a note-taking support for your lecture on...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Why was Sir Newton so important to the field of science? Pupils discuss his contributions, specifically his Third Law, as they learn about gravity and the center of mass. They work multiple problems to ensure their understanding and...

The focus of this resource is to teach young students about some of the basic components of force and motion. Students view slides which give examples of gravity, force, motion, magnets, and wind. Then, they must choose one of those...

Many realistic situations of active forces are presented here along with diagrams. The direction of movement, acceleration and gravity are labeled on each picture to help understanding.  A summary of the direction of acceleration...

Examples and practice questions will help real-life understanding of the Principle of Moments concept. These great slides define the types of levers and pivots, and then give examples of the typical seesaw situations that help the...

May the mass times acceleration be with you. The presentation covers forces, Newton's three Laws of Motion, momentum, and vectors.

Is your class struggling with Newton's Second Law? Then show them a presentation that covers everything physics scholars need to know about forces. Starting with gravity, the slides focus on Newton's Laws of Motion, and end with an...

Go around and around in your physics class with this presentation on circular motion. Diagrams bring the definition to life. Formulas for angular acceleration, centripetal force, gravitation, and potential in a radial field are given....

There is scant information on these slides: definitions of gravity and force, and the fact that objects fall at the same speed. Two slides give learners an activity to try to demonstrate aspects of gravity. Although the activities are...

Explore gravity, force, and mass as some of the natural forces in the universe. Each slide provides information and examples that describe each concept. Learners are encouraged to throw a basket ball and a bean bag into the air to...

A summary of the science between gravity.  Your students will find the resources links useful and the definition summaries relevant. This slideshow could be used to accompany a lecture or even for independent study.

These simple slides are basic, but clear, in their summary of physical forces. Definitions of friction, air resistance, gravity, freefall and projectiles are given along with a couple of helpful diagrams. More examples always help to...

Scholars build a boat using an assortment of materials such as foam plates, aluminum foil, and skewers, then test its buoyancy with pennies. Challenge boat builders to construct the strongest or fastest boat in a healthy competition with...

Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...

Introduction your class to famous astronomers with a presentation that also covers Newton's Laws of Gravitation, Kepler's Laws of Planetary Motion, both uniform and nonuniform gravitational fields, and how to calculate the gravitational...
