No Stomach for It: Investigating Antacid Medication
You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Antacid and Uncle Heartburn
Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Tritration: Standardization of a Base and Analysis of Stomach Antacid Tablets
Do antacid tablets really do what they claim? An experimental lesson attempts to answer this question. Individuals practice the process of titration during the first part of the experiment. They then use those skills to neutralize an...

Antacid Tablet Race
Students compare the reaction rates of effervescent antacid tablets under different conditions. They investigate methods of increasing the power of rocket fuels by manipulating surface area and temperature.
Curated OER
Antacid Tablet Race
Students complete experiments to determine how rocket fuel is affected by surface area and temperature. They compare the reaction rates of antacid tablets. They discuss their results to complete the instructional activity.

Antacid Lesson Plan
Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Gas Law Investigation
Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Acid Rain Experiments
Learners define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Learners answer the questions why are...
Curated OER
Chemical or Physical?
Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...
