Activate middle schoolers' minds with this physical science activity. Learners vary the diameter of gears and the number of teeth on them to find how energy output is affected. This writeup features well-developed background...

Students explore the difference between compound and simple machines in this six lessons of this unit. The purpose and importance of a variety of types of simple machines and the effects of friction are investigated.

Fourth graders discover the principles and uses of gears noting that they can be used to change the direction of motion or the speed of an object. They may also change the force and/or distance through which an object turns. They then...

Students conclude that magnets and magnetic fields can produce electricity. Students also understand how a small motor works and how gears work. Students describe how energy can transform along a pathway.

Students explain the relationship between magnetism and electricity. In this physics lesson plan, students describe the transformation of energy. They create an electromagnet and investigate the factors affecting its strength.

Students examine the concept of angular momentum and its correlation to mass, velocity, and radius. They listen to a teacher-led lecture, conduct an experiment with rotational inertia, angular momentum, and rotation speed by making...

Young scholars explore simple machines used in the home. In this simple machines lesson, students discover that many household items are constructed from simple machines. Young scholars interact with nutcrackers, peelers, egg slicers,...

Learners work together to discover the concept of angular momentum. They participate in experiments in which they test rotation and relate it to an object's mass. They participate in a literacy activity in which they compare mythology...

Students identify the advantages and disadvantages of wind farms and turbines. They examine how weather conditions can affect their effectiveness and how engineers are trying to solve the problem. They discover how engineers use this...
