In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

En esta actividad sobre la densidad de los líquidos, los participantes ven si las gotas de colorante se hunden en diferentes soluciones de agua.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

In this activity, learners will explore how animal in cold areas stay warm.

In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners discover a brain process called habituation.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

In this activity, learners will experiment with different materials that can melt and change ice.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.

In this online game, learners must purchase power plants for their city.
