Blocking the Sun: Earth's External Heat Engine and the Earth's Atmosphere
Using a detailed worksheet, advanced earth science learners examine radiation data and graphs. They compare the solar energy reaching different latitudes and the effects of the atmosphere on insolation. The exercises are comprehensive. The graphs and diagrams on the worksheets are a little lighter than the typed font, so you might have to explain if they are hard to read. Otherwise, this is a terrific resource for challenging your high schoolers.
