For younger students, you may want to use larger 8x8 squares. They must get two approvals from me before making their petri dishes. All three ways have merit. how the jelly seperates the pollutants form air??????? Walk to errands when possible. In this classroom experiment, you will use graph paper and petroleum jelly to "catch" particulate air pollutants for classroom observation. Air pollution is usually thought of as smoke from large factories or exhaust from vehicles. Sounds like a great experiment! They can never fully control all the variables and I want them to see that other factors may have influenced their results. Burning fossil fuels releases gases and chemicals into the air. On this basis, she and her team can calculate and simulate measures to reduce air pollution. Animal farms may produce food, but they also produce … First, you will want to trim the graph paper so that it fits on your backer card without overlapping the edges. For our experiment we used 14x14 graph paper. After all groups are done recording data, have them discuss their findings.

What Do Students Think is Best for AP Exam Review? Set-up is easy, and material cost is low- you can obtain everything you need for under $5 for a classroom of 30. Reply I aim to develop scientifically literature citizens. Analyzing the weaknesses in their lab help them identify flawed experiments later on in life and on the AP® Exam. Air pollution is a health and environmental issue across all countries of the world, but with large differences in severity. Have them count the number of particulates in each square of the graph paper, and record them in a table laid out with the same number of squares as the graph paper. Depending upon the age of your students, you may choose to adjust what size graph paper you use in order to facilitate the math in obtaining averages. Most air pollution comes from energy use and production, says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC.
