Lesson Plan: Atomic Number, Mass Number, Isotopes and Isotopic Ratios, and Isotopic Compositions as Climate Proxies

As a high school or undergraduate teacher of Chemistry or Earth Sciences, you can use this set of computer-based tools to help you in teaching atomic number, mass number, isotopes and isotopic ratios, the use of isotopic ratios to calculate temperature, and the use of isotopic composition to recreate past temperatures and climate.
