Climate change can be difficult to understand because climate is a complex, multi-competent system. Approach climate change from a chemistry perspective to understand the impact of human led changes to the environment by looking at how the ozone layer works, the role of carbon dioxide in ocean acidification, and a take-home activity to explore ocean acidification on your own.
More educational resources (and all of the simulations linked above) can be found at The American Chemical Society’s Chemists Celebrate Earth Week page, https://www.acs.org/content/acs/en/education/outreach/ccew/educational-resources.html. There’s even some coloring to relax with while you’re celebrating Earth Day. Just be sure to reuse or recycle your paper when you’re done!
