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, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

This is an online game that explores speed, range and momentum. Learners will pick the winners in a 16-team tournament in 3 events: Tug-o-war, sprint, and marathon.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners build simple catapults and use them to launch cotton balls.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

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

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

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

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.
