Colorful & kid friendly! This Powerpoint presentation is to be used along with guided notes (fill in the blank). Students will learn the various gases that make up the atmosphere, the changes in atmospheric pressure and the changes in atmospheric temperatures. Students will then learn the details of each of the five layers: troposphere, stratosphere, mesosphere, thermosphere & exosphere. Colored graphics are included. You may want to have students copy one of the drawings of the layers on a separate sheet of white paper to use as a guide. You can also use paint samples from a hardware store! The variants in color help students visualize the different layers and pressure! Fill in the blank notes are included in store.
