In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

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.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.
