Curated OER
Quality Control at Kality Krunchers Dill Pickle Factory
In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the lesson requires...

Quantitative Analysis of Vinegar Lab
In this quantitative analysis worksheet, learners perform a lab to determine the amount of acetic acid in vinegar by doing a titration. They use an indicator phenolphthalein to determine the endpoint of the titration.

Infectious Disease Detectives
Students participate in a simulation of how diseases are transmitted. Each student holds a test tube, with only one containing the "disease" while the others have water. They move around the room until told to stop. Using droppers to...

How Germs Spread
Young scholars conduct a test to help them visualize the spread of
germs. They identify that a pandemic is an epidemic (an outbreak of an infectious disease) that spreads across a large region or even worldwide. Finally, students state...

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...
