This PPT presentation is set up as a lecture on Biomes. Students can take 2 column notes using the PPT that is presented in class. Blue on the left (substantive material), and red on the right (examples). The PPT is set up to only show one part at a time so that students cannot take notes ahead of you. I use this PPT as the introduction to the science unit. I also have a final assessment on my page that you can use at the end of the unit.
