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...
Curated OER
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.

The effectiveness of Antacids
Students design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they determined...
Curated OER
Outgassing
Students demonstrate the concept of outgassing and to explain the origins of the earth's atmosphere. They perform a simple experiment using glass jars, two antacid tablets, and some water. This experiment does a good job in demonstrating...

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...
Curated OER
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...

Physical and Chemical Reactions - Factors Which Affect Reaction Rate
A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Can Acid and Bases Remedy the Body?
Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.
Curated OER
A Plop and Fizz
Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.

Aqua-Thrusters!
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 tablet and water -...
Curated OER
Stomach Chemistry
Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.
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...
Curated OER
Chemical Weathering
Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.
Curated OER
Wacky Water Critters
Learners visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each organism...
Curated OER
Pop Rockets
Students study Newton's Third Law of Motion which involves action and reaction. They discover what makes a rocket go and then design and construct a rocket that will launch the furthest using the pressure created by an antacid tablet...

Keep it Bottled Up: Linear Rates of Pressure Increase
Pupils explore linear functions in this instructional activity when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the...
Curated OER
Vision Props of Signed Numbers
Students explore the concept of titration. In this titration lesson, students observe acid and alkaline reacting. Students discuss pH factor, measuring acidity, neutrality, and alkalinity of liquids. Students put the pH of liquids on a...
