Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

An experiment where students launch a simple rocket using a film canister, water, and an antacid tablet.

While building and testing model rockets fueled by antacid tablets, students are introduced to the basic physics concepts on how rockets work. Students revise and improve their initial designs. Note: This activity is similar to the...

When two or more chemicals react, other substances such as gases may be produced. The rate at which the reaction takes place can be affected by a number of different factors including temperature. In this activity, you will see how...

In this activity, students' will use a pH sensor to record pH versus time data as an antacid tablet neutralizes acid in lemon juice. They will model the pH data with a modified exponential function.

In this activity, students investigate the simulated use of solid rocket fuel by using an antacid tablet. Students observe the effect that surface area and temperature has on chemical reactions. Also, students compare the reaction time...

In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid...

Students design and build a paper rocket around a film canister, which is used as the engine. An antacid tablet and water are put into the canister, react to form carbon dioxide gas, and act as the pop rocket's propellant. With the lid...
