Energy Conversions: Science and the Use of Energy

More than 100 cities around the world have shifted from fossil fuels to renewable energy sources. Scholars investigate a city wanting to make this switch, but needs help determining how to make the shift. Groups consider all options,...

Become energy efficient with a presentation that covers the Law of Conservation of Energy with friction. It also includes energy transformations, power, and units of measurement.

Why do athletes load up on carbohydrates the evening before a competition? The lesson helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars perform an experiment...

In 1942, scientists first observed the first man-made nuclear reactor. The video introduces the history of nuclear energy from military development through today. It highlights the types of nuclear reactors built and the reasons as well...

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in...

Energy has many forms ... but very few sources! How do we present this to young scientists? Explore the Definitions of Energy, PS3A, in a video about the Next Generation Science Standards. The narrator keeps it simple by relating...

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...

Tired of blowing up countless balloons to illustrate orbital shapes around an atom? Give your lungs a break and use an interactive instead! Learners observe s, p, d, and f orbitals through the first four energy levels using hydrogen as a...

If renewable energy sources are the best option, why aren't they used on a global scale? Junior environmentalists explore the benefits and problems associated with energy sources such as solar, wind, and biomass with a short video and...

Is the ice cooling down the water or is the water melting the ice? Here is a simulation that explores thermal energy transfer with iron, brick, and water. It demonstrates the flow of energy and what happens when each material is either...
