In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

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 "Sid the Science Kid" activity from Episode 108: My Ice Pops, learners observe reversible change while thinking about ways to make ice melt.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

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

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

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 create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity, learners construct paper airplanes that twist and turn.

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, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners make instant ice cream without using a freezer.
