In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
