Class members use an air quality monitor to measure the amount of gas-phase pollutants emitted by different sources. Groups choose three different sources and make predictions about what the monitors will detect. Teams then expose...

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity worksheet covers the differences in genotypes and...

How many humans does it take to power a light bulb? The 10th part of a 25-lesson Energy Systems and Solutions unit has learners conduct an experiment to calculate power. They then use the results to determine how many classmates they...

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...

Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO MINDSTORMS NXT bricks and light sensors. They begin by analyzing a set of standard solutions with known...

Students are introduced to measuring and identifying sources of air pollution, as well as how environmental engineers try to control and limit the amount of air pollution. In Part 1, students are introduced to nitrogen dioxide as an air...

Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur...

In this activity, students will capture and examine the particles to gain an appreciation of how much dust, pollen and other particulate matter is present in the air around them. Students will place "pollution detectors" at various...
