With the Schoenbein Ozone Paper Chemistry Laboratory Kit, students learn about “good and bad” ozone, duplicate Schoenbein’s test paper and test for ozone, and gather data to make conclusions about ozone concentrations in their hometown.
One of the most important decisions the human race will have to make this century is what to do about the destruction of the ozone layer. In 1839, ozone was discovered by Christian Schoenbein. He developed a way to measure ozone in the air using a mixture of starch and potassium iodide spread on filter paper. In this activity, your students will learn about “good and bad” ozone, duplicate Schoenbein’s test paper and test for ozone and gather data and make conclusions about ozone concentrations in their hometown.
A sling psychrometer or other humidity-measuring device is required but not included. Complete for 30 students working in pairs.
