Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.

Students experiment with a new material—aerogel. Aerogel is a synthetic (human-made) porous ultra-light (low-density) material, in which the liquid component of a gel is replaced with a gas. In this activity, student pairs use aerogel to simulate the environmental engineering application of cleaning up oil spills. In a simple and fun way, this activity incorporates density calculations, the material effects of surface area, and hydrophobic and hydrophilic properties.

By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.

The Phoenix metropolitan area, like many large cities, has problems with air pollution at certain times of the year. You can do a simple experiment to determine some of the factors that affect air pollution.

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 pollutant and how it is quantified. Major sources are identified, using EPA bar graphs. Students identify major cities and determine their latitudes and longitudes. They estimate NO2 values from color maps showing monthly NO2 averages from two sources: a NASA satellite and the WSU forecast model AIRPACT. In Part 2, students continue to estimate NO2 values from color maps and use Excel to calculate differences and ratios to determine the model's performance. They gain experience working with very large numbers written in scientific notation, as well as spreadsheet application capabilities.

Join Chesapeake Bay Foundation educators Maya, Rick, and Norah as they lead you on a journey through the Chesapeake Bay watershed. Investigate how we are all part of a watershed as you twist and turn from the Appalachian Mountains, through the rivers and streams of Piedmont, all the way down to the Chesapeake Bay. Along your journey, you’ll meet the unique critters that call the watershed home. You’ll also explore what you can do in your own neighborhood to protect the environment and become a Backyard Bay Saver! 

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).

Learn about migration, the seasonal movement of animals from one location to another. Join the Center staff and migratory bird experts as they explain why birds migrate, and the dangers that they may face along their journeys. Learn how to help migrating birds and why we should be concerned about more than just our own backyards.

In this lesson, the music and visuals of the Gorillaz album Plastic Beach is used to introduce students to the issue of plastic waste. Students are asked to calculate the percentage of plastic that goes unrecycled internationally, and illustrate a model of polyethylene to better understand why the molecular makeup of plastic creates both benefits and drawbacks. Finally, they evaluate various projects that are currently being undertaken to curb plastic waste, and develop their own similar program or project that they could employ on a local level.

In some cities, especially large cities such as Los Angeles or Mexico City, visible air pollution is a major problem, both for human health and the environment. A variety of sources contribute to air pollution, but personal vehicles account for one of the main sources. Though each car has relatively low emissions when compared to vehicles of the 1970s, there are so many more cars on the road now that their emissions play a large role in overall pollution. In this activity, students think about alternate ways to power a vehicle to reduce emissions. Student teams design an eco-friendly car using the engineering design process, and make a presentation to showcase their product.

This video lesson aims to motivate students about chemistry and to raise their awareness about how chemistry helps in solving certain environmental problems. In this lesson, the air pollution problem created by cars and other vehicles is presented. The lesson will highlight causes of this problem, harmful products from it and possible solutions. There will also be discussion of ways to convert the pollutants produced by burning oil in vehicles into more friendly products.

Students observe and discuss a simple balloon model of an electrostatic precipitator to better understand how this pollutant recovery method functions in cleaning industrial air pollution.

Engineers design methods of removing particulate matter from industrial sources to minimize negative effects of air pollution. In this activity, students will undertake a similar engineering challenge as they design and build a filter to remove pepper from an air stream without blocking more than 50% of the air.

Students learn about a special branch of engineering called bioremediation, which is the use of living organisms to aid in the clean-up of pollutant spills. Students learn all about bioremediation and see examples of its importance. In the associated activity, students conduct an experiment and see bioremediation in action!

Students observe a burning candle and the byproducts given off through the burning process. This observation leads to a discussion to the effects of air pollution on our lives.

Learn about one of the biggest impacts that humans have on their environment—Litter. It isn’t just an aesthetic problem; it has serious impacts on habitats, wildlife health, as well as human health and safety. The consequences of even small acts of littering can be far-reaching and long-lasting. Join the Wildlife Center staff and watershed conservation authorities to learn more about the problems litter can pose, as well as a variety of ways that you can help reduce litter.

By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.

Students design and build model landfills using materials similar to those used by engineers for full-scale landfills. Their completed small-size landfills are "rained" on and subjected to other erosion processes. The goal is to create landfills that hold the most garbage, minimize the cost to build and keep trash and contaminated water inside the landfill to prevent it from causing environmental damage. Teams create designs within given budgets, test the landfills' performance, and graph and compare designs for capacity, cost and performance.

In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.
