Aspirin Testing—
Student Laboratory Kit
By: The Flinn Staff
Oh‚ my aching head! I need some pain reliever, but which brand of aspirin should I take? Students will:
• Experimentally determine the aspirin content of three brands of over-
the-counter pain relievers using acid–base neutralization titration techniques and then compare the amounts to those listed on the bottle.
• Compare the effects of regular, buffered and enteric-coated aspirin on a “simulated stomach.”
• Compare the actual amount of aspirin and cost-effectiveness of each tablet and then make comparisons and draw conclusions about differ- ent brands of aspirin.
• Learn the history and chemistry of aspirin as well as about the differ- ent types on the market with the extensive background material.
Instructor Notes and reproducible student handouts included. All aspirin samples, chemicals and specialized equipment are provided in the kit.
Complete for 30 students working in pairs.
Analyzing Calcium in Milk—Laboratory Kit
By: The Flinn Staff
General, Organic and Biological Chemistry
Healthy body, good teeth, strong bones—the benefits of calcium in good nutrition are well known. Milk and dairy products are widely promoted as an important source of calcium in the diet. Explore the chemistry behind the nutrition with this experiment that measures the amount of calcium in milk. Students analyze the calcium content in skim milk by microscale titration with EDTA. An excellent activity to “bone-up” on calcium properties and titration skills!
Complete for 24 students working in pairs.
Cheese-Making—
Student Laboratory Kit
By: The Flinn Staff
Learn how fun it is to make cheese right in your lab—your students will love it, too! This kit teaches the basic process, adapted centuries ago, of cheese-making using a harmless bacteria and a fermentation-derived clot- ting enzyme. This sneak peek into the industrial process of cheese-making will allow your students to appreciate the fairly specific temperatures and pH requirements of enzymes and the commercial value of bacteria!
Complete for 30 students working in pairs.
