Students learn how to take bearings using orienteering compasses. They also learn how to describe a bearing and find an object in the classroom using a bearing.

In this lesson, students are shown the very basics of navigation. The concepts of relative and absolute location, latitude, longitude and cardinal directions are discussed, as well as the use and principles of a map and compass.

Drinking water comes from many different sources, including surface water and groundwater. Environmental engineers analyze the physical properties of groundwater to predict how and where surface contaminants will travel. In this lesson, students will learn about several possible scenarios of contamination to drinking water. They will analyze the movement of example contaminants through groundwater such as environmental engineers must do (i.e., engineers identify and analyze existing contamination of water sources in order to produce high quality drinking water for consumers).

Students will learn the difference between global, prevailing and local winds. In this activity, students will make a wind vane out of paper, a straw and a soda bottle and use it to measure wind direction over time. Finally, they will analyze their data to draw conclusions about the prevailing winds in their area.

In this lesson, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces. The goal of this lesson is for students to apply their existing knowledge about the four forces affecting flight and apply engineering design to develop a sound glider. They will also communicate the reasoning and results of any design modifications made.

Students learn about wind energy by making a pinwheel to model a wind turbine. Just like engineers, they decide where and how their turbine works best by testing it in different areas of the playground.

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 will learn about how tornadoes are formed and what they look like. By creating a water vortex in a soda bottle, they will get a first-hand look at tornadoes.

Through this activity, Bernoulli's principle as it relates to winged flight is demonstrated. Student pairs use computers and an online virtual wind tunnel to see the influence of camber and airfoil angle of attack on lift. Activity and math worksheets are provided.

In this activity, students create a book, newspaper or other published work to communicate what they have learned about engineering and the environment.

Contamination in drinking water sources or watersheds can negatively affect the organisms that come in contact with it. The affects can be severe causing illness or, in some cases, even death. It is important for people to understand how they can contribute to the contaminants in drinking water and what treatment can be done to counter these harmful effects. Students will learn about the various methods developed by environmental engineers for treating drinking water in the United States.

The purpose of this activity is to demonstrate Newton's 3rd Law of Motion, which is the physical law that governs thrust in aircraft. The students will do several activities that show that for every action there is an equal and opposite reaction.

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.
