Come On Baby Light My Fire

What does it cost to keep the lights on? Through a hands-on activity, class members use a watt meter and determine the amount of energy different types of light bulbs use. The class then determines the financial and environmental cost of...

This resource provides an explanation of NASA's GALEX mission and how the space-based telescope can view distant galaxies as they were billions of years ago. The resource also discusses the other aspects of galaxies that GALEX is able to...

Here is an activity that allows class members to explore and research robotics and the idea of automation. Working with a gaming model, pupils write an algorithm to "automate" the solution. Individuals also conduct and present research...

It's "Green light, go!" with this lesson! STEM classes are illuminated with the history of traffic signals and how the engineering design has improved over time. They also learn about patents for new inventions. Finally, they research in...

My friend told me how electricity is measured and I was like Watt! In the hands-on activity, learners explore electricity by building circuits, both parallel and series. They also determine how increasing the number of light bulbs and...

Though UV radiation can damage skin, it isn't all bad. The third installment in a six-part series allows the class to study the structure and function of skin. They learn about the different types of skin cancer and the SPF rating...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Installment four of the nine-part series on using Audacity describes saving, exporting, and deleting podcasts you've made. If you read the excerpt under this video as it comes on you're screen you'll notice a web link. This takes you to...

Students assemble a safety light system, select a variable for testing and investigate the variable. A new light system is built using class data on design qualities. A report and oral presentation are prepared for the selected design.

How much solar energy is available at my location? An engaging resource provides a presentation along with script to give the class background information on determining solar radiation. Pupils then work through a worksheet to estimate...
