Comparing Carbon Calculators part of Examples
Carbon calculators, no matter how well intended as tools to help measure energy footprints, tend to be black boxes and can produce wildly different results, depending on the calculations used to weigh various ...
Long Term Ecological Resources part of Examples
Students analyze data on temperature and precipitation collected from 26 different Long Term Ecological Research sites and compare them with annual net primary productivity. The students then form an ecological rule to explain their results.
Using Mass Balance to Understand Atmospheric CFCs part of Examples
Students use an interactive online mass balance model help understand the observed levels of chlorofluorocarbon CFC-12 over the recent past.
Water Quality-Total Dissolved Solids part of Examples
Students use a microcomputer connected to a conductivity probe to measure the total dissolved solids in local area water samples.
Electrical Analysis of Wind Power part of Examples
For this experiment, students use a DC motor as a generator and various shaped turbine designs to test which design produces the most electrical power. Using a fan to generate the "wind", students attach ...
Annotating Change in Satellite Images part of Examples
During this exercise, students compare a series of satellite images taken 3-4 years apart to investigate the effects of human land use and annotate the images using ImageJ software.
Comparing Sunscreens part of Examples
Students use a microcomputer connected to an ultra-violet sensor to compare the relative blocking power of different SPF sunscreens for the UVB region of the solar spectrum.
