In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners examine their tongue and taste buds.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.
