In this two-part activity, students design and build Rube Goldberg machines. This open-ended challenge employs the engineering design process and may have a pre-determined purpose, such as rolling a marble into a cup from a distance, or let students decide the purposes.

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

Students learn about oil spills and their environmental and economic effects. They experience the steps of the engineering design process, starting by brainstorming potential methods for oil spill cleanup. They model small-size oil spills in plastic bins, and then design, build and re-design oil booms to prevent the spread of oil spills. Oil booms are like floating fences on the water surface to help contain and collect spilled oil. During a reflective session after cleaning up their oil booms, students come up with ideas on how to reduce oil consumption to prevent future oil spills. A PowerPoint presentation is provided.

Algorithms are one of the foundations of our technological world, and are driven by the scientists and engineers behind the scenes that write all of these different algorithms. This lesson is intended to get students interested in the inner workings of algorithms and the capabilities associated with them. We start by engaging students with very simple examples of algorithms which they can associate with. We then discuss Google’s PageRank algorithm for ranking the importance of websites based on the other websites that link to them, and play a fun game that can be used to find the same results as the PageRank algorithm.

Students use the engineering design process to solve a real-world problem—shoe engineering! Working in small teams, they design, build and test a pair of wearable platform or high-heeled shoes, taking into consideration the stress and strain forces that it will encounter from the shoe wearer. They conclude the activity with a "walk-off" to test the shoe designs and discuss the design process.

For this maker challenge, students decide on specific design requirements (such as good traction or deep cushioning), sketch their plans, and then use a variety of materials to build prototype shoes that meet the design criteria. The bottoms (soles) of sneakers provide support, cushioning, flexibility and traction as makes sense for the sport or activity. In addition, some sneakers are intended to be fashionable with cool colors, materials or added height. Sneakers are engineered products that use a mix of materials to create highly functional, useful shoes.

Engineers design methods of removing particulate matter from industrial sources to minimize negative effects of air pollution. In this activity, students undertake a similar engineering challenge as they design and build a filter to remove pepper from an air stream without blocking more than 50% of the air.

Music: Dream of A Day - Density & Time

Students explore the physics exploited by engineers in designing today's roller coasters, including potential and kinetic energy, friction and gravity. First, they learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars as they travel around the track. During the associated activity, students design, build and analyze model roller coasters they make using foam tubing and marbles (as the cars).

Students investigate the idea of linear approximation. Students apply mathematical modeling, specifically linear approximation, to an already collected data set to make a prediction. In this lesson, students first engage in a warm-up that is not a perfectly linear data set, being exposed to this for the first time. Students take on the role as a packaging engineer to learn the process to apply linear approximation modeling: collecting data, creating a graph, drawing a line-of-fit, creating a model in the form of an equation, defining the model’s variables, and evaluating with the model. Students ultimately use their linear model to predict the net weight of cereal in grams contained by 260 square inches of cardboard packaging.

To gain a better understanding of the roles and functions of components of the human respiratory system and our need for clean air, students construct model lungs that include a diaphragm and chest cavity. They see how air moving in and out of the lungs coincides with diaphragm movement. Then student teams design and build a prototype face mask pollution filter. They use their model lungs to evaluate their prototypes to design requirements.

Music: Sky Scraper - Geographer

Students are introduced to brainstorming and the design process in problem solving as it relates to engineering. They perform an activity to develop and understand problem solving with an emphasis on learning from history. Using only paper, straws, tape and paper clips, they create structures that can support the weight of at least one textbook. In their first attempts to build the structures, they build whatever comes to mind. For the second trial, they examine examples of successful buildings from history and try again.

Music: Comparsa-Latinesque - Kevin MacLeod

To understand the challenges of satellite construction, student teams design and create model spacecraft to protect vital components from the harsh conditions found on Mercury and Venus. They use slices of butter in plastic eggs to represent the internal data collection components of the spacecraft. To discover the strengths and weaknesses of their designs, they test their unique thermal protection systems in a planet simulation test box that provides higher temperature and pressure conditions.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

Student groups are challenged to design and construct model towers out of newspaper. They are given limited supplies including newspaper, tape and scissors, paralleling the real-world limitations faced by engineers, such as economic restrictions as to how much material can be used in a structure. Students aim to build their towers for height and stability, as well as the strength to withstand a simulated lateral "wind" load.

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—a unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an important concept in the engineering design process. Students create graphite-based fibers using sodium alginate as the medium and a calcium coagulation bath, which is similar to the way in which graphene-based fibers are created in engineering research laboratories. Students then determine the factors that contribute to resistivity and vary these parameters to optimize fiber resistivity.

The purpose of this lesson is to introduce students to the basic elements of our Earth's crust: rocks, soils and minerals. They learn how we categorize rocks, soils and minerals and how they are literally the foundation for our civilization. Students also explore how engineers use rocks, soils and minerals to create the buildings, roads, vehicles, electronics, chemicals, and other objects we use to enhance our lives.

Continuing the Asteroid Impact challenge, student teams test rocks to identify their physical properties such as luster, hardness, color, etc., and classify them as igneous, metamorphic or sedimentary. They complete a data table to record all of the rock properties, and then answer worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.

In a class demonstration, the teacher places different pill types ("chalk" pill, gel pill, and gel tablet) into separate glass beakers of vinegar, representing human stomach acid. After 20-30 minutes, the pills dissolve. Students observe which dissolve the fastest, and discuss the remnants of the various pills. What they learn contributes to their ongoing objective to answer the challenge question presented in lesson 1 of this unit.
