Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

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

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this physics activity, learners will explore buoyancy.

Everybody loves bubbles, and this is the best bubble recipe ever!

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.
