Students can compare their results with published results of scientists. Both sites contain similar versions of this activity. (CM)

Summary of Reviews

Reviewer: Carrie Morrill 5 stars
Comments: Each of the two sites has added to the original EPA exercise in useful ways. The UCAR site has data from a second lake, in Colorado. The Maine site has a neat way of getting students to plot their data in a more quantitative way, useful data sheets and handouts (available at site homepage) and a tie-in to CO2 variations.

Reviewer: Ellen DeBacker 5 stars
Comments: This activity has students investigate ancient climates by using fossil pollen in a simulation. There is a choice of looking at data for Washington or Colorado. I prefer the layout of the UCAR site as it is much easier to use and access all the additional data.
