This PowerPoint works as a phenomenal supplement to the Houghton Mifflin Harcourt Fusion workbooks for 8th grade Science! This lesson covers Topographic Maps from Unit 2 (Earth's Surface) and is completely aligned to the Ohio New Learning Standards for Science. I am providing all teachers who purchase this item the ability to change the standards for your particular state, so please feel free to adjust accordingly! The Science Fusion workbooks and the Think Central portal are fantastic resources, created by Houghton Mifflin Harcourt, and I cannot recommend them enough for appropriate scientific inquiry! Please feel free to contact me if you have any questions regarding this resource.
