Ahoy, matey! Here is an engineering expedition that mini mariners are sure to be swept away by! After reading a brief description and history of periscopes, they work in crews to construct one. Use this activity to enhance a lesson on...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Do you have blossoming astronomers who seek to understand the electromagnetic spectrum? Assist them with exploring electromagnetic radiation and the electromagnetic spectrum as the class conducts various activities to demonstrate...

The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities. 

Don't shine like a diamond, refract light like a diamond. Young scientists use an acrylic block and a laser light to observe refraction. Advanced scholars figure the sine of the angles of reflection and incidence as well as mastering...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and electricity, young...

While we are all familiar with what happens when you turn on a light bulb, Albert Einstein was convinced that there was more happening than meets the eye. The video describes his extension of the research of others to ultimately...

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...

How do lighting types affect energy efficiency? Explore different types of lighting and the energy they use. Pupils learn about types of lights and calculate the energy used during a typical school year. They discover that being energy...
