In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

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 take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

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 explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

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 fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners create their own archaeological profiles.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners examine the culture and history of the tomb site.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
