Students apply their knowledge about mountains and rocks to transportation engineering, with the task of developing a model mountain tunnel that simulates the principles behind real-life engineering design. Student teams design and create model tunnels through a clay mountain, working within design constraints and testing for success; the tunnels must meet specific design requirements and withstand a certain load.

Students develop their understanding of air convection currents and temperature inversions by constructing and observing simple models.

Students build their own two-cell batteries. They also determine which electrolyte solution is best suited for making batteries.

Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid gasoline-electric cars and their advantages over conventional gasoline-only-powered cars.

Groundwater is one of the largest sources of drinking water, so environmental engineers need to understand groundwater flow in order to tap into this important resource. Environmental engineers also study groundwater to predict where pollution from the surface may end up. In this lesson, students will learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow.

This lesson plan examines the properties of elements and the periodic table. Students learn the basic definition of an element and the 18 elements that build most of the matter in the universe. The periodic table is described as one method of organization for the elements. The concepts of physical and chemical properties are also reviewed.

Students practice the ability to produce clear, complete, accurate and detailed design drawings through an engineering design challenge. Using only the specified materials, teams are challenged to draw a design for a wind-powered car. Then, they trade engineering drawings with another group and attempt to construct the model cars in order to determine how successfully the original design intentions were communicated through sketches, dimensions and instructions.

Students learn how the endocrine system works and compare it to the mail delivery system. Students discuss the importance of communication in human body systems and relate that to engineering and astronauts.

In this activity, students will use vector analysis to understand the concept of dead reckoning. Students will use vectors to plot their course based on a time and speed. They will then correct the positions with vectors representing winds and currents.

In this design challenge, students learn about the Vikings from an engineering point-of-view. While investigating the history and anatomy of Viking ships, they learn how engineering solutions are shaped by the surrounding environment and availability of resources. Students apply this knowledge to design, build and test their own model Viking ships.

Students learn about the causes, composition and types of volcanoes. They begin with an overview of the Earth's interior and how volcanoes form. Once students know about how a volcano functions, they learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an eruption, seeing how a volcano gets its shape and provides us with clues to predict a blast.

In this activity, students participate in a series of timed relay races using their skeletal muscles. The compare the movement of skeletal muscle and relate how engineers help astronauts exercise skeletal muscles in space.

Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.

People use energy in all aspects of their lives for cooking, lighting and entertainment. Much of this energy use takes place in buildings, such as our homes. To save money and reduce the impact on our environment, many people are reducing their energy use. One way is to hire engineers to perform home energy audits to understand the ways we use energy and identify ways we can conserve energy. In this activity, students act as energy conservation engineers and identify the ways energy is conserved or wasted. They also learn many ways to personally conserve energy everyday.

Students use inclined planes as they recreate the difficult task of raising a monolith of rock to build a pyramid. They compare the push and pull of different-sized blocks up an inclined plane, determine the angle of inclination, and learn the changes that happen when the angle is increased or decreased.

In this service-learning engineering project, students follow the steps of the engineering design process to design a hearing testing device. More specifically, they design a prototype machine that can be used to test the peripheral vision of partially-blind, pre-verbal children. Students learn about the basics of vision and vision loss. They also learn how a peripheral vision tester for adults works (by testing the static peripheral vision in the four quadrants of the visual field with four controllable lights in specific locations). Then they modify the idea of the adult peripheral vision tester to make it usable for testing young children. The class designs and builds one complete prototype, working in sub-groups of four or five students each to build sub-components of the project design.

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 learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and survive floods.

Students learn about the water cycle and its key components. First, they learn about the concept of a watershed and why it is important in the context of engineering hydrology. Then they learn how we can use the theory of conservation of mass to estimate the amount of water that enters a watershed (precipitation, groundwater flowing in) and exits a watershed (evaporation, runoff, groundwater out). Finally, students learn about runoff and how we visualize runoff in the form of hydrographs.

Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.
