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

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
