Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

Beat the summer heat by exploring the properties of color. Scientists view a video explaining the relationship between light absorption and energy transfer using variables including intensity, time, and wavelength. A multiple-choice...

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...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

All chemical reactions require energy. To explore thermodynamics, classes read and discuss its laws, exothermic and endothermic reactions, enthalpy in many forms, calculate enthalpy problems, and use Hess' Law to calculate enthalpy of a...
