Collect Oxygen Over Water
In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.
Exploring Baking PowderAdd to list Details
In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
Formation of a PrecipitateAdd to list Details
Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
Gas Production: Blow up a balloon!Add to list Details
In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.
Which Powder is It?Add to list Details
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
Hot and ColdAdd to list Details
In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.
In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.
Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.
Snowstorm in a Jar
In this activity, learners will experiment with density and chemical reactions to create a flurry activity.
Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.
Glow Fast, Glow Slow: Alter the Rate of a Reaction!Add to list Details
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.
Color Changes with Acids and BasesAdd to list Details
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.
Red, White and Blue I DemonstrationAdd to list Details
In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.
Change in Temperature: Endothermic ReactionAdd to list Details
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Chemistry in the Kitchen
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
In this activity, learners use simple materials to construct a balloon-powered pinwheel. The pinwheel is a great way to investigate Newton's Third Law of Motion.
Neutralizing Acids and BasesAdd to list Details
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.
This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.
Floating CandlesAdd to list Details
In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.
Production of OxygenAdd to list Details
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.
