Teaching Tip on 'The Earth's Atmosphere'

I think this is a great site for a variety of people. It allows for different types of learners to understand the information presented. There were pictures that corresponded with the written information to cater to visual learners. The activities are helpful and provide for a fun way to retain the information. The only negative experience that I had involved problems with opening the crossword puzzles. Overall, I would definitely recommend this site to others.
