In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

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

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 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 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 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.

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.

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

This quiz lets you estimate your annual radiation exposure.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this online game, learners attempt to send a rocket ship to various targets. Learners can adjust the angle and thrust of the rocket before it is launched.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners will use magnets and household items to create a structure that allows paperclips to appear like they are floating.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity, learners overlap the three primary colors to see how all other colors are made.
