If you put on clothes that were washed in a washing machine, rode in a car, ate food from a fridge, warmed up lunch in a microwave, or played a video game, you used an electric motor. Try this science fair project and you'll learn how to...

This companion website for a PBS documentary about Hans Hofmann includes all the essential information about Hofmann, whose reputation as a teacher almost eclipses his reputation as an artist. Wonderful site for exploring how artists...

See how forces affect various items that are pushed or pulled.

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

A learning module reviewing how much force is needed to push or pull objects. Also learn about the force of gravity.

Students use inclined planes as they recreate the difficult task of raising a monolith of rock to build a pyramid. They compare the push and pull of different-sized blocks up an inclined plane, determine the angle of inclination, and...

You have probably heard the word "force" before in conversations. Here are a few examples: "the rocket had a lot of force at blast off" or "the force of the storm blew the roof off the building." What is force? Force is defined as a push...

What caused the influx of African Americans and European immigrants into urban centers in the late 19th century? Learn about some of the discriminatory and anti-immigrant laws that were enacted to restrict their rights. Includes a chart...

Experiment with different sizes of parachutes to find out if size matters when slowing the descent of the parachute. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

A rich collection of highly engaging learning modules on topics related to population and settlement. Covers six main areas - population growth, population change, population migration, land use, settlement characteristics and patterns,...

Why do people move? This curriculum unit tackles the complex questions about the causes of individual versus large-scale migration as well as the global effects of migration. Clear lesson plans and objectives are included.

This tutorial is to introduce students to the concept of forces. Tutorial includes activities, content and teacher notes.

In this guided inquiry activity, young scholars will use 2 marbles of different size and a box to investigate what makes the marbles move and what will cause the marbles to change speed and direction.

Through the use of movement and observation, the students will be able to identify objects that can be moved and identify and problem solve how to move objects. Included in this lesson are videos of the activity, a vocabulary chart, and...

Understand the concept of "work" and the use of levers.

Third graders learn how a catapult works and build their own.

Third graders create their own parachutes to understand the concept of gravity and the effect it has on objects.

Learn about the movement of people from one place to another with this informative look at migration. Discover the push and pull factors, migration into Europe, and the main types of migration.

This lesson will explain how to calculate net forces on an object being pushed or pulled. It is 2 of 4 in the series titled "Calculating Forces."

This lesson will explain how to calculate net forces on an object being pushed or pulled. It is 3 of 4 in the series titled "Calculating Forces."

In this physics lab students discover the invisible magnetic field where the magnet can exert its power to push or pull.

Classical physics describes and predicts how things work in our everyday environment. Football falls well into the limits of classical physics. In football we encounter many situations where only a few interactions, maybe only one push...

[Free Registration/Login may be required to access all resource tools.] Featurea the definition of combining forces: Pulling down and pushing up, forces acting in opposite directions, forces acting in the same direction.

Students define potential energy and explore the relationship between potential energy and field. How does potential energy change when things are pushed or pulled? Where does the energy that was used to charge the Van de Graaff...
