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.

Students gain a basic understanding of electrical circuits. They build wire circuits and pass paperclips through the mazes, trying not to touch the wires. Touching a wire with a paperclip causes the circuit to close, which activates an indicator.

The engineers at Splash Engineering (the students) have been commissioned by Thirsty County to conduct a study of evaporation and transpiration in their region. During one week, students observe and measure (by weight) the ongoing evaporation of water in pans set up with different variables, and then assess what factors may affect evaporation. Variables include adding to the water an amount of soil and an amount of soil with growing plants.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.

Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some period of time. Students create a model waterwheel and use it to calculate the amount of power produced and work done.

Students experience civil and environmental engineering by planning a housing development in an existing biome, while also protecting the native species that live there. They conduct research, draw plans, make brochures and give presentations, with each team having a member serving as a project manager, civil engineer, environmental engineer and graphic designer. The best designs creatively balance the needs and resources necessary to support both the native species and human infrastructure.

This activity focuses on getting students to think about bacteria, water quality and water treatment processes. Students develop and test their hypotheses about the "cleanliness" of three water samples prepared by the teacher. Then they grow bacteria in Petri dishes from the water samples. They learn how private septic systems and community sewage and wastewater treatment plants work, the consequences to the surrounding environment and wildlife from human wastewater, and what measurements of the released "clean" water are monitored to minimize harm to receiving rivers and lakes.

Students learn how motion capture (mo-cap) technology enables computer animators to create realistic effects. They learn the importance of center of gravity in animation and how to use the concept of center of gravity in writing an action scene. Note: The literacy activities for the Mechanics unit are based on physical themes that have broad application to our experience in the world — concepts of rhythm, balance, spin, gravity, levity, inertia, momentum, friction, stress and tension.

Students further their understanding of the engineering design process while combining mechanical engineering and bioengineering to create assistive devices. During this extended activity (seven class periods), students are given a fictional client statement and required to follow the steps of the engineering design process (EDP) to design a new wristwatch face for a visually impaired student at their school. Student groups share their designs with the class through design presentations. A successful design meets all of the student-generated design requirements, including the development of a new method of representing time that does not require the sense of sight. Through this activity, students design, construct and iterate classroom prototypes of their watch designs.

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

Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second, smaller test tube is then placed upside-down inside the solution. As the yeast cells respire, the carbon dioxide they produce is trapped inside the inverted test tube, producing a growing bubble of gas that is easily observed and measured. Students are presented with the procedure for designing an effective experiment; they learn to think critically about experimental results and indirect observations of experimental events.

Students are introduced to the role of electricity and magnetism as they build speakers. They also explore the properties of magnets, create electromagnets, and determine the directions of magnetic fields. They conduct a scientific experiment and show cause-effect relationships by monitoring changes in the speaker's movement as the amount or the direction of the current change.

Students learn about archives and primary sources as they research original historical documents. While preparing an imaginative first-person account as if witnessing an historical event, they learn to appreciate the value of the first-person, eye-witness account and understand its limitations. Note: The literacy activities for the Mechanics unit are based on physical themes that have broad application to our experience in the world — concepts of rhythm, balance, spin, gravity, levity, inertia, momentum, friction, stress and tension.

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.

In addition to the associated lesson, this activity functions as a summative assessment for the Using Stress and Strain to Detect Cancer unit. In this activity, students will create a 1-D strain plot in Microsoft Excel depicting the location of a breast tumor amidst healthy tissue. The results of this activity will function as proof of the accuracy and reliability of the students' breast cancer detection design.

Students perform a macroinvertebrate survey to gauge the health of a local river. They collect water samples and count macroinvertebrates to learn how the health of a river's ecosystem can be determined by its river insect population.

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.

To explore different ways of using solar energy, students build a model solar water heater and determine how much it can heat water in a given amount of time. Solar water heaters work by solar radiation and convection.

Student teams learn about and devise technical presentations on four reproductive technology topics pregnancy ultrasound, amniocentesis, in-vitro fertilization or labor anesthetics. Each team acts as a panel of engineers asked to make a presentation to a group of students unfamiliar with the reproductive technology. Each group incorporates non-lecture elements into its presentation for greater effectiveness. As students learn about the technologies, by creating a presentation and listening to other groups' presentations, they also learn more about the valuable skill of technical communications.
