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 on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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 set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.
