[Free Registration/Login Required] Learn about the relationship between position, velocity, and acceleration for two objects in one-dimensional motion. Experiment with varying approaches to the race for both Irwin and Ruthie to see how...

Videos that accompany activities that are hands-on challenges that focus on the engineering design process. They use simple materials, allow for multiple solutions, and are ideal for ages 9-12.

Students experiment with different materials and objects to make a sled that will slide down the ramps.

[Free Registration/Login Required] Learn about adding force vectors in two dimensions using the example of a painting hanging from two strings. Experiment with variables of weight and angles to hang a portrait in this physics simulation....

[Free Registration/Login Required] Learn about the relationship between velocity and position for a swimmer. Adjust the velocity of the legs, streamline, and arms to experiment with the slope of velocity in the simulation swimmer. Dig a...

Students conduct an experiment to determine the relationship between the speed of a wooden toy car at the bottom of an incline and the height at which it is released. They observe how the photogate-based speedometer instrument "clocks"...

[Free Registration/Login Required] Learn about the relationship between position and velocity for a model rocket during launch and in free-fall. Experiment with rocket mass, rocket thrust, and rocket burn time to understand the...

In the first of two lessons of this curricular unit, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Student teams use spring scales to drag objects, such as a ceramic...

A lesson about friction can be found on this website. Students will experiment to see how motion and frictional force affect the game of football.

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

Students experience firsthand one of the most common water treatment types in the industry today, flocculants. They learn how the amount of suspended solids in water is measured using the basic properties of matter and light. In...

Fantastic variety of printable activities that cover motion-related principles. Topics include the following: experiments (engineering, structures, forces and energy, fluids, sound and light, patterns, human body); arts & crafts;...

For this rocket experiment, middle schoolers will investigate the question, "Which amount of water will cause the rocket to stay in the air the longest?" Students will compare how long the rocket was in the air with how much water was in...

Experience the effect of friction, air resistance, and applied force upon a sledder. The speed, acceleration, and force values are displayed as the sled moves. Learners can vary the mass of the sledder and the size of the parachute...

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This pair of...

An investigation for students to understand plate tectonics by using models to see how motion and forces act on the plates. Students can use these models to see the connection between Newtonian Laws to Earth materials. Lesson plan...

A collection of experiments where students can learn about how friction works and affects the physical world. At the end, students design a tortoise to win by slowing it down using friction. Lesson includes explanation of the concept of...

Extensive site for teachers provides some helpful resources that pertain to plant and animal cells. Includes a microscope diagram as well as plant, animal and pond labs. Also contains links to structures and mechanisms, matter and...

Students are asked to create a bungee jump that will protect a hard-boiled egg from breaking. A force sensor is needed to measure the push/pull forces on the egg. Data is inserted into force-time graphs. After completing three...

In this culminating activity of the unit which highlights how forces play a role in engineering design and material choices, students explore and apply their knowledge of forces, friction, acceleration, and gravity in a two-part experiment.

Observe the impact of weight on the speed of a pendulum.

Many students of physics do not believe in centripetal/inward forces. Even after completion of a thorough physics course, such students will still incorrectly believe that an object moving in a circle experiences an outward force. Use...

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

Students conduct an experiment that will reinforce their understanding of Newton's Second Law. Using simple objects, students control force, mass, and acceleration, and how each is related to each other.
