What You'll Learn
Biodegradable materials
One of the major sources of pollution is plastic waste, which ends up in our oceans, clogging waterways, and littering the soil. Biodegradable plastics can be used to address this issue. They have properties similar to traditional plastics but with a minimized environmental impact in terms of carbon dioxide emissions. However, despite their promise, biodegradable plastics still face challenges in realizing the goal of a zero-waste circular economy. The adoption of biodegradable plastics requires a shift in consumer behaviour and the right waste management practices, such as composting.
Another way to promote the use of biodegradable materials is through natural fiber-reinforced polymer composites. These composites are made from natural fibers, which serve as excellent reinforcing materials for polymer composites. They offer several advantages, including good mechanical properties, manufacturing benefits, and a solution to environmental contamination. Natural fibers are renewable, have high tensile strength, are low-cost, and lightweight. They have replaced non-renewable synthetic fibers in various applications due to their environmental benefits.
Chitin and chitosan, derived from marine crustaceans and arthropods, are additional examples of biodegradable materials with high strength and non-toxicity. They find applications in medical and pharmaceutical sciences, tissue engineering, food packaging, and more.
To educate students about biodegradable materials and pollution, a hands-on science project can be designed. In this project, students bury a range of objects, such as an apple core, leaves, plastic packaging, and Styrofoam, and observe their breakdown over a month. This experiment helps students understand biodegradability and the impact of non-biodegradable materials on the environment.

Air pollution sources
Air pollution is a pressing issue that arises from various sources, both human-generated and natural. These sources encompass a range of activities and phenomena, contributing to the degradation of air quality. Here is a detailed look at some of the key sources of air pollution:
Vehicles and Transportation:
One of the primary sources of air pollution is transportation, particularly vehicles like cars, trucks, trains, and boats. The combustion of gasoline and natural gas in these vehicles releases volatile organic compounds (VOCs) and nitrogen oxides, which are major air pollutants. Additionally, vehicle exhaust and emissions significantly contribute to air pollution, especially in urban areas. This includes ground-level ozone, carbon emissions, and fine particulate matter, collectively known as Traffic-Related Air Pollution (TRAP).
Industrial and Power Sources:
Industrial activities and power plants are significant stationary sources of air pollution. Power plants, refineries, and industrial boilers release pollutants that contribute to ground-level ozone formation. Additionally, coal combustion in power plants has been linked to adverse health effects, including increased mortality and neurological disorders such as dementia. These sources emit large amounts of pollution from a single location, known as point sources.
Residential and Commercial Activities:
Residential and commercial activities also contribute to air pollution. Residential wood burning, for instance, accounted for a significant percentage of fine particle emissions in Minnesota. Backyard fires, heating and cooling equipment, and gas-powered yard equipment are common neighborhood sources of air pollution. Local businesses, construction equipment, and auto-body shops are also included in this category. While each of these sources may not produce a substantial amount of pollution individually, collectively, they contribute to a significant portion of air pollution.
Agricultural and Natural Sources:
Agricultural activities, such as the use of pesticides and combustion engines in farming equipment, release pollutants into the air. Wildfires are another natural source of air pollution, emitting particles and gases that can have long-lasting impacts on air quality. While natural sources may not always create ongoing pollution problems, they can be significant, especially when combined with human-generated sources.
Area and Mobile Sources:
Area sources refer to the collective impact of multiple smaller pollution sources that may not be significant on their own but can contribute to overall air pollution levels. Mobile sources, on the other hand, account for more than half of all air pollution in the United States, according to the Environmental Protection Agency. This includes vehicles, as mentioned earlier, but also construction and agricultural equipment, snowmobiles, and more.

Acid rain
To demonstrate the effects of acid rain, a simple experiment can be conducted. This experiment uses three containers, with varying levels of water and vinegar, to simulate rain with different levels of acidity. Flowers or plants are then placed into each container, and observations are made over 24 hours. The flower or plant in the container with neutral pH water will remain the freshest, while those in the acidic solutions may show signs of damage to their leaves, impacting their ability to photosynthesize.
Another experiment involves watering three separate plants with water, a small amount of acid (vinegar or lemon juice), and a large amount of acid, respectively. These plants are then left in the sun for several days, with regular watering. At the end of the experiment, students can assess the effects of the acid on the plants, observing any differences in growth and overall health.
Through these experiments, students can gain a better understanding of the impact of acid rain on living organisms and the environment. They can also explore possible solutions, such as discussing materials that could be added to the soil to counteract the effects of acid rain or learning about the technologies and laws that engineers are developing to reduce the release of harmful pollutants.
Additionally, it is important to address the human factor contributing to acid rain. Students can be encouraged to consider ways to reduce the burning of fossil fuels, such as by driving less, carpooling, using public transportation, biking, or transitioning to electric vehicles. Educating students about the impact of their choices can empower them to make a difference in their personal lives and inspire them to pursue environmental sciences or engineering to combat this issue.
