Climate Generation recently released two free climate science units:

• Healthy Habitats: Climate Change Action for K-2
  • Contains three primary lessons on habitats and climate
• Experience Energy: Grades 3-8
  • Incorporates SEL, social studies, math and ELA to investigate energy use, climate impacts, and solutions

You need to create a FREE account to log in. You will also be asked to “add to cart” but you do not have to pay for the resource. Donations are of course encouraged by Climate Generation.
