In reflection of what teachers may need for Earth Day, I drew these graphics for teachers wanting to do a Science Unit on Pollution, it's causes, and what we can do about it.
I've created over 30 graphics for this pack. The posters are letter-sized 8.5" x 11"). They are all PNG files created from vector graphics, so most of them are a very forgiving if you need to re-size them.
I am pretty passionate about the environment and what steps we can take to make children aware of the global issues we face today.
