Young scholars identify and separate the different zones of the beach by observation. They investigate beach zonation by gathering and comparing sand samples gathered from different areas of the beach.

Students investigate and experiement with a 9-volt motor. They will use the connecting wire and battery pack to discover fans.

Students study myths regarding four earthquakes myths. They receive a list of supplies each family should have at home to prepare for an earthquake and construct an "Earthquake Preparation" poster showing some of the most important items...

In this science activity, students select twenty-five scientists from the list to fill in their bingo card. Then they match each of the scientists listed to their correct description strip.

In this science worksheet, middle schoolers use the key code on the right to unscramble each of the scientists. They also match each of the scientists found to their correct description.

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...

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.

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 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.

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 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...

Designed for Grade Eight, this collection of lessons provides information, examples and quizzes related to simple machines. Elementary students studying this topic will find this site informative as well.

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 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...

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...

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 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.

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...

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...

Using diagrams, illustrations, and relevant data, students will calculate the net work done on an object, the change in an object's velocity, and the change in an object's kinetic energy.

By the end of this section, you will be able to explain gravitational potential energy in terms of work done against gravity, show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh,...

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...

By the end of this section, you will be able to explain work as a transfer of energy and net work as the work done by the net force and to explain and apply the work-energy theorem.
