Greenhouse Effect—Demonstration Kit
By: The Flinn Staff
What is the greenhouse effect? How did it get this
name? Set up model mini-greenhouses and demon-
strate the principles of the greenhouse effect for your students. In less than one class period, the measured temperature differences in the mini-greenhouses will be dramatic and reflect the exact trend that the greenhouse effect is having on the planet Earth. The results from this demonstration will serve as a launch pad for further research and stimulate lively discussion about the significance of the world data being collected. The mini-greenhouse bottles, stopper, and reflecting flags are provided in the demonstration kit and can be reused many times. Teacher Demonstration Notes included.
Concepts: Absorption, reflection, greenhouse effect.
Time Required: 30 minutes
Materials Provided: Aluminum strips, black construction paper, soda bottles, rubber stoppers.
Note: Three thermometers and a 200-watt light source are required but not included.
Make Your Own Ozone Test Paper—
Student Laboratory Kit
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.
Air in a Bottle—Demonstration Model
By: Scott Newkirk
Front Range Community College, Fort Collins, CO
This amazing model will help your students visualize the gases that make up the air and clear up the misconception that there is more oxygen in the air than nitrogen. The 3-liter model contains one million different colored spheres. Each color represents a different gas found in the Earth’s atmosphere. As students examine the model, they are challenged to determine which color represents which gas. A great educational value that can be easily incorporated into your lessons for many years to come!
