How are forces and motion important to a swing set? Scholars explore the concepts of force and motion using swing sets. In preparation for their own STEM design project, individuals take surveys and data from peers, complete labs on...

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

Simple doesn't mean useless. Individuals learn how simple machines benefit the user by changing the amount of effort. A seven-lesson unit begins with an overview of simple machines and then incorporates activities that allow the user to...

Planning an elementary science unit has never been simpler! These twelve lessons guide young scientists through an exploration of simple machines and their many uses in the real world before asking them to apply their learning...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in 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...

By the end of this section, you will be able to discuss the general characteristics of friction, describe the various types of friction, and calculate the magnitudes of static and kinetic frictional forces.

By the end of this section, you will be able to calculate coefficient of friction on a car tire and to calculate ideal speed and angle of a car on a turn.

By the end of this section, you will be able to define nonconservative forces and explain how they affect mechanical energy, and to show how the principle of conservation of energy can be applied by treating the conservative forces in...

In the following interactive students will begin to calculate coefficient of friction on a car tire. They will also calculate ideal speed and angle of a car on a turn.

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...

[Free Registration/Login may be required to access all resource tools.] Understand the effects of magnitude of force pairs between objects. Know the differences between kinetic and static friction.

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

By the end of this section, you will be able to define net force, external force, and system; understand Newton's second law of motion; and apply Newton's second law to determine the weight of an object.

Students apply Newton's laws to more diverse physical settings where multiple forces from varying origins interact. To aid in condensing the physical setting into mathematical expressions, the free body diagram is used in this module...

By the end of this section, you will be able to define drag force and model it mathematically, discuss the applications of drag force, define terminal velocity, and perform calculations to find terminal velocity.

A collection of resources on how humans use machines and tools to meet their needs. Covers simple and complex machines, subsystems that transfer forces, mechanical advantage, speed ratio, the effect of friction, efficiency, the science...

Explore the effects of forces around us in the world.

By the end of this section, you will be able to state Hooke's law; explain Hook's law using graphical representations between deformation and applied force; discuss the three types of deformations: changes in length, sideways shear, and...

This lesson will introduce the concept of friction and explain how it can affect forces. It is 2 of 5 in the series titled "Friction."

This lesson will introduce the concept of friction and explain how it can affect forces. It is 3 of 5 in the series titled "Friction."

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.
