To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

Did you know horsepower is actually based on the power of a horse? 60 horse power is the equivalent of being pulled by a team of 60 horses! Viewers will learn other interesting facts like this from a presentation that begins with the...

Fourth graders experiment with electricity and magnetism and build an electromagnetic motor. In this electromagnetism lesson, 4th graders use household objects to show electrostatics and magnets and compasses to show magnetism. They...

First of three lessons, this is a great start to a unit on energy. As you demonstrate, learners discover different types of energy and how it is converted from one form to another. They then focus in on the generation of electricity by...

Fourth graders examine the paths that electrical currents travel. They create a current of electricity using flashlights, bulbs, batteries, wires and tape. They determine how to create a closed circuit that will light the bulb. They...

In a classic activity, emerging electricians test various objects for electrical conductivity in a circuit. Each group constructs a simple circuit by following a diagram. Predictions are made and objects are inserted into the circuit,...

An interesting series of puzzles and word games are available in this multi-page collection, which focuses on coal. Learners practice math and language arts skills as they solve the puzzles, and learn many facts about coal at the same time.

How do Earth's changes affect humans? Pupils learn about physical and chemical changes on Earth and how they lead to erosion, earthquakes, and volcanoes. Using the text, they also explore the concepts of electricity and magnetism by...

I don't get electricity jokes, watts so funny about them? The 13th in a series of presentations covers energy, motors, currents, generating electricity, calculating electrical energy cost, transformers, and batteries.

Students explore the relationship between magnetism and electricity byby explaining how the model motor operates. They observe the the spinning of a coil of copper wire that is part of a circuit.

Combine science and playtime with the final lesson in an innovative unit. Scholars apply everything they have learned in previous lessons to build their own motors/generators and use it in a toy of their own design. 

What is the difference between a form of energy and a source of energy? This first activity in a series of 19 lessons uses demonstrations and discussions to introduce energy to the class. Through using hand-generator flashlights,...

Students identify the different professions that are related to electricity.  In this professions lesson students write a story about performing one of these jobs and share it with the class.

In this static electricity worksheet, students complete nine questions about electron charges, coulombs, potential energy, voltage and the Van de Graaf generator.

Learners examine why electricity is distributed at high voltage and the functions of transformers.  For this electromagnetism lesson students study at what frequency electricity is distributed. 

Students identify hypotheses related to static electricity, to begin to test the hypotheses, to begin to develop conclusions related to observations, to demonstrate that like charges repel and unlike charges attract each other, to name...

Four demonstrations with the Van der Graaf generator are delineated for you to share with your science classes. Instructions, explanations, and safety precautions are included. However, a background explanation of the static electricity...

Students explore static electricity using the Van de Graaff generator. In this physics lesson plan, students construct their own Van de Graaff using simple materials. They explain how charges accumulate on this device.

 In this online worksheet learners answer a series of 14 essay or short answer questions explaining the DC generator theory. The correct answer is available to check their responses to each question. The questions vary in...

All work and no play make Jack a dull boy, while all text and no graphics make Energy a dull presentation. It is informative, teaching viewers about work, conservation of energy, and sources that can be used to generate electricity. It...

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