In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.
In this lesson, students explore solid waste and its effects on the …
In this lesson, students explore solid waste and its effects on the environment. They will collect classroom trash for analysis and build model landfills in order to understand the process and impact of solid waste management. Students will understand the role of engineers in solid waste management.
In this lesson, students will explore the causes of water pollution and …
In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.
In this activity, students will review and evaluate the ways land is …
In this activity, students will review and evaluate the ways land is covered and used in their local community. They will also consider the environmental effects of the different types of land use. Students will act as community planning engineers to determine where to place a new structure that will have the least effect on the environment.
In this activity, students work as engineers to build and observe a …
In this activity, students work as engineers to build and observe a model landfill. They will understand the process and pitfalls of the use of landfills as a method for the waste disposal.
Students collect, categorize, weigh and analyze classroom solid waste. The class collects …
Students collect, categorize, weigh and analyze classroom solid waste. The class collects waste for a week and then student groups spend a day sorting and analyzing the garbage with respect to recyclable and non-recyclable items. They discuss ways that engineers have helped to reduce the accumulation of solid waste.
Students observe and discuss a simple model of a wet scrubber to …
Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.
Students observe a model waterwheel to investigate the transformations of energy involved …
Students observe a model waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine. Students work as engineers to create model waterwheels while considering resources such as time and materials, in their design. Students also discuss and explore the characteristics of hydropower plants.
Students are introduced to some essential meteorology concepts so they more fully …
Students are introduced to some essential meteorology concepts so they more fully understand the impact of meteorological activity on air pollution control and prevention. First, they develop an understanding of the magnitude and importance of air pressure. Next, they build a simple aneroid barometer to understand how air pressure information is related to weather prediction. Then, students explore the concept of relative humidity and its connection to weather prediction. Finally, students learn about air convection currents and temperature inversions. In an associated literacy activity, students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and are introduced to the role played by metaphor in language development. Note: Some of these activities can be conducted simultaneously with the air quality activity (What Color Is Your Air Today?) of Air Pollution unit, Lesson 1.
Students develop awareness and understanding of the daily air quality using the …
Students develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper. They explore what engineers can do to help reduce poor air quality.
Students are introduced to the concepts of air pollution and air quality. …
Students are introduced to the concepts of air pollution and air quality. The three lesson parts focus on the prerequisites for understanding air pollution. First, students use M&Ms to create a pie graph that expresses their understanding of the composition of air. Next, students watch and conduct several simple experiments to 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). Finally, students develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper. In an associated literacy activity, students explore the environmental history timeline.
In this activity, students use models to investigate the process and consequences …
In this activity, students use models to investigate the process and consequences of water contamination on the land, groundwater, and plants. This is a good introduction to building water filters found in the associated activity, The Dirty Water Project.
Students develop an understanding of the effects of invisible air pollutants with …
Students develop an understanding of the effects of invisible air pollutants with a rubber band and hanger air test and a bean plant experiment. They also learn about methods of reducing invisible air pollutants.
In this activity, students develop an understanding of how engineers use wind …
In this activity, students develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed.
In this activity, students create a book, newspaper or other published work …
In this activity, students create a book, newspaper or other published work to communicate what they have learned about engineering and the environment.
Students develop an understanding of visible air pollutants with an incomplete combustion …
Students develop an understanding of visible air pollutants with an incomplete combustion demonstration, a "smog in a jar" demonstration, building simple particulate matter collectors, and exploration of engineering roles related to air pollution. In an associated literacy activity, students learn basic marketing concepts and techniques, and the principles of comparative analysis, while creating an advertisement for a hybrid vehicle. Note: You may want to set up the activities for Air Pollution unit, Lessons 2 and 3, simultaneously as they require extended data collection time and can share test sites.
