In this genetics activity, learners discover how to extract DNA from green split peas.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.

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.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

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

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.

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

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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 design a bungee jump for an egg using nylon stockings.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
