In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

In this activity, learners discover how solar energy can be used to heat water.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
