Compositional Layers & Physical Layers Earth’s Compositional Layers & Physical Layers TEACHER NOTES below Materials per student- blank sheet of copy paper, scissors, ruler, colored pencils (optional) Super-simple teacher notes: Have students do everything shown on the screen! (see notes on later slides for more details) Other Notes: To see a preview of this lesson on video go to http://www.interactivescienceteacher.com/earths-compositional-physical-layers-earth-science-lessons-preview/ Change any text you like in the ppt Teachers-this is definitely a graphic organizers you’ll want to make for yourself beforehand so you have an example to show, and because it makes you more descriptive when doing the lesson. Print these slides to help you present. Click Print, then under “Print what:” select “Handouts (6 Slides per page)” Lots more notes on later slides in this ppt… Thanks for using this lesson!
