Students observe two chelae. They write three differences they observe in their notebooks. Students suggest a hypothesis which would explain these differences. They dissect the chela. Students analyze the lobster claw as a mechanical lever.

Students investigate the human circulatory system by experimenting with hoses.  In this human body lesson, students create a system of hoses simulating the circulatory system which they utilize to pass objects through....

Students explore biology by researching living cells. In this living organism lesson, students participate in a role-playing activity in which all the students in class form one plant cell by portraying specific parts of a cell. Students...

In this grammar instructional activity, students finish ten sets of unfinished sentences by joining them together with a variety of -ing expressions.

Students explore the different types of lifters through a series of activities. In this physics lesson, students explain the mechanics involved in the lifter designs. They compare aluminum versus zinc lifters.

By the end of this section, you will be able to define conservative force, potential energy, and mechanical energy; explain the potential energy of a spring in terms of its compression when Hooke's law applies; and use the work-energy...

This is a summary of the information in Chapter 7: Work, Energy, and Energy Resources for the AP Physics I course online.

This is a list of 74 problems/exercises to solve over the content of Chapter 7: Work, Energy, and Energy Resources from the AP Physics online text.

This is a glossary of words and definitions of terms having to do with work, energy, and energy resources.

[Free Registration/Login Required] This module has students using a simple machine to learn about the relationship between work, force, and energy.

In the following video Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent...

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 define nonconservative forces and explain how they affect mechanical energy. They will show how the principle of conservation of energy can be applied by treating the conservative...

In the following interactive students will begin to explain how an object must be displaced for a force on it to do work. They will also explain how relative directions of force and displacement determine whether the work done is...

A handout for a university calculus course. It looks at the application of Newton's Laws to calculate work and energy for a particle of mass with a force being exerted on it.

In the following interactive students will define conservative force, potential energy, and mechanical energy. They will explain the potential energy of a spring in terms of its compression when Hooke's Law applies. Students will also...

The intricate relationship between work and mechanical energy is depicted in the animation for students to be able to visualize.

Suppose that a car traveled up three different sloped roadways from the base of a mountain to the summit of the mountain. Which path would require the most energy? See this animation and explanation for help.

This page explores the quantitative relationship between work and mechanical energy in situations in which there are no external forces doing work. It is a basic analysis of situations in which mechanical energy is conserved. Examples...

This activity will provide students with a qualitative understanding of the Work-Energy Theorem, especially on how the energy transferred depends on the distance over which the force is applied.

In the following interactive students will begin to explain work as a transfer of energy and net work as the work done by the net force. They will also explain and apply the work-energy theorem.

The mathematical model for the relationships between work and energy serves to model physical problems and, more importantly, predict natural and man-made phenomena. Students discover the relationships which serve as a powerful...

Demos and activities in this lesson are intended to illustrate the basic concepts of energy science--work, force, energy, power etc., and the relationships among them. The "lecture" portion of the lesson includes many demonstrations to...

The activity investigates conservation of energy. Some topics explored are friction, kinetic energy, conservation of energy, and potential energy. The resource consists of video clips, lecture notes, practice problems, and exam...
