In this activity, learners build a scale model of the solar system using a roll of toilet paper.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

Many people think the different stages in the life of a star are actually different types of stars, rather than just stages in the life of a single star.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

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

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.

In this weather-related activity, learners make a portable cloud in a bottle.

This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

In this game, learners are volcanoes that must complete several steps to erupt. Starting at home plate, learners draw cards until they have enough points to move to first base.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners take core samples of candy bars with a straw and carefully observe & excavate their sample, modeled after what the NASA Perseverance rover will do on Mars.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.
