Breathe some life into product design. Pupils learn about the stages of product creation, use, and disposal—sometimes called a cradle-to-grave assessment. They see how this cycle relates to the life cycle of organisms.

Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...

Using the resource is probably the most efficient way to learn about efficiency. The 18th installment of a 25-part Energy Systems and Solutions unit has pupils investigate energy efficiency through discussions and associated activities....

Power up your lessons with an energetic resource. Scholars learn about work, force, energy, and power. They consider the relationships between these quantities through hockey puck scenarios and make calculations using formulas.

Need a activity? Problem solved. Scholars learn about the problem-solving process in the sixth installment of a 25-part Energy Systems and Solutions unit. The particular process in question is the Technological Method of Problem Solving.

Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...

Power up! Class members research a type of power production using a great resource featuring a real-world problem. Groups select a type of power generation and pretend that they represent an engineering firm for their chosen power type....

Show your students how to make their work easier. The first lesson in a series of 10 introduces the class to work and the way simple machines can be make work easier. The simple machines scholars can find in everyday items are inclined...

What is energy, anyway? Use this featurette as an introduction to your middle school energy unit. It successfully touches each of Earth's physical systems, the sun as our main source of energy, and the flow of energy through the food...

Are you looking for a reading resource about the efficiency of power systems? Here is one that introduces the output/input ratio, measurement of energy by joules or calories, and efficiency ratings. For STEM classes that are learning...

The question of affordable energy in the United States is debated by high schoolers. Each participating team prepares a multimedia presentation as they prepare to debate. Research skills, creativity, and critical thinking are all...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Explore the world's water without leaving the classroom! In this second of three uncomplicated but wonderful activities, physical science learners feel the pressure of water. They discover that the deeper the water, the stronger the...

Some commonly accepted concepts are not completely valid. In this video, the following ideas are thoroughly explained away: Light cannot be effected by gravity Velocity is additive The earth appears to be flat Not only is this an...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount...

Youngsters make a mental assessment of electricity-consuming appliances in their homes and then evaluate them for the amount of energy consumed. They learn how to use power meters and measure the electrical consumption of several...

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare...

An informative video covers the density of the particles just after the Big Bang, as well as the concept that whenever a particle was released it would merge with something else. Sal develops the concept of being able to receive and...

After reviewing the equation and terms from the previous video, Sal, the narrator, works through an example of an item that is fighting with the force of gravity. He introduces potential energy and begins to explain conservation of...

Start working with work and energy with your higher-level physics class. The narrator, Sal, starts off with defintions of the two terms, showing how they are related to one another. He then goes into an example and derives a formula for...

Cute manga style animated Aya is your host for this short but good explanation of valence electrons and forming ions. She explains how to know whether to add or subtract electrons when ions are forming. Note: The voice work is a little...

Voltage in relation to electrical circuits is the topic of this clip. First potential energy is explained in terms of gravity, then the idea is conveyed to describe how the chemicals in a battery act as potential energy for an electrical...
