Tracking Ozone
Learners track an ozone event in Groton, CT. They compare weather changes and the subsequent ozone levels. Also, they make comparisons and determinations about ozone levels.
Curated OER
Multiplying Microbes
Students examine environmental conditions that effect bacteria growth. They culture bacteria, design and conduct an experiment, and identify the conditions that effected the bacteria growth using the scientific method.

Ozone Pollution: Smog Alert
Students simulate the development of smog. They discover how it forms naturally in nature. They read news articles about the ozone and pollution. They discuss what they can do to lower the pollution they generate.
Curated OER
Insect Place Mat
Students are introduced to new concepts and vocabulary by using a creative project of making a placemat. The kinesthetic learners will benefit from this kind of project. Also it is great for those who think artistically.
Curated OER
Ozone Pollution: Smog Alert
Students explain ozone pollution and make them aware of how it is formed. They simulate the development of smog and infer how it occurs in nature.
Curated OER
Creating and Analyzing Graphs of Tropospheric Ozone
Students create and analyze graphs using archived atmospheric data to compare the ozone levels of selected regions around the world.
Curated OER
Is There Really Life on Mars?
Students examine the work of scientists and determine how they test their theories.
Curated OER
Air Pollution: A Local and Global Problem
Young scholars work together to solve the problem of air pollution. Using the Internet, they research the pollution problem in one city. Using the data, they develop their own solution and pitch it to the class. They must identify the...
Curated OER
Cells and Cancer
Young scholars idenitfy that cancer is a growth of mutated cells and that cancer cells are only one type of cell that causes disease in our body. They also identify that all eukaryotic cells contain a nucleus, cytoskeleton, and a cell...

The Sun Safety Activity Guide
Students examine the sun safety guide. They identify the dangers of getting too much sun and not protecting themselves. They participate in hands-on activities to finish the lesson.
Curated OER
Trouble in the Troposphere
Learners Use data sets from MY NASA DATA to produce graphs comparing monthly and yearly ozone averages of several U.S. cities. They analyze and evaluate the data and predict trends based on the data. In addition, they discuss and...
