This is from a list of Glacier Image Pairs which are images of glacier taken in the same location but at different times (30-100 year apart). The change is striking. This is part of a grades 4-8 lesson plan from here, which is part of the windows to the universe portal with an abundance of information including a number of lesson plans for secondary education.

NASA Global Maps Create maps showing average surface temperature for different time periods. Great for discussing the difference between a distribution and a averages. The graph here is for Jan 2011 and we see that the east coast of the U.S. was slightly below average in temperature even though globally the average temperature was 0.46C warmer.

A great graph by the EIA that shows Energy Flow by source and sector in the U.S. in 2009. This site has an abundance of energy consumption and production information along with definitions and general information. The EIA has plenty of graphs, charts, consumption and production information, along with definitions and general information on their EIA Energy Explained page.

The World Top Incomes Database will create graphics like this one. It gives the share of income by the top 1% by for years 1955 to the present for the U.S. (top line), Canada, France, Germany, Sweden, and UK. You can choose the countries, years, and other variables to plot (choose graphics from the main page). Data is also available.

This graph comes from the article Record high temperatures far outpace record lows across the U.S.. This could be used as part of a simulation exercise and discussion on randomness vs trends.
