Your class might be surprised to learn that mirrors have been around since the first century AD! Young scientists explore reflection and refraction of light through a series of challenges. They use this knowledge to design their own...

Uncover the exciting interactions of light energy and matter ranging from color to optical illusions. Participants explore color using red and green apples, differences between reflection and refraction, and descriptions of related...

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...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Learners explore the wave energy that is generated and transferred in the ocean. Through the use video and the Internet, students explore the aspects of a wave and how its energy affects the ecology of the seashore.

Students define electromagnetic radiation, list major categories and uses of electromagnetic waves, identify potential health risks with electromagnetic waves, and demonstrate understanding of Plank's constant by solving quantitative...

Students explore naturally magnetic elements. In this magnets lesson, students examine the periodic table of elements. Students discover the parts of an atom and determine which three elements are magnetic.
