Students collect data from a sugar-level simulation by categorizing different food and drink solutions and measuring their impact on glucose levels. They then use this data to train a machine learning model using the "Machine Learning for Kids" platform. By inputting and organizing their data, students train the model to predict blood sugar responses and classify meals as either healthy or unhealthy. They test their model’s accuracy with new inputs and make adjustments to improve its performance. Through this hands-on process, students gain an understanding of how machine learning works, the importance of high-quality data, and how these technologies can support real-world health applications, such as managing diabetes.

Cold Funk Funkorama - Kevin MacLeod

How can you tell if harmful bacteria are growing in your food? Students learn to culture bacteria in order to examine ground meat and bagged salad samples, looking for common foodborne bacteria such as E. coli or salmonella. After 2-7 days of incubation, they observe and identify the resulting bacteria. Based on their first-hand experiences conducting this conventional biological culturing process, they consider its suitability in meeting society's need for ongoing detection of harmful bacteria in its food supply, leading them to see the need for bioengineering inventions for rapid response bio-detection systems.

Students learn about the engineering design process and how products may be reinvented to serve new purposes. Working in groups, students design a type of slime. After creating their slime, the teacher turns out the lights and the students see that the slime they made actually glows in the dark! The groups investigate how to take their new discoveries and apply them to industrial applications. Once they have determined a use for their glowing slime, each group must build/design and test their product outside of class. The groups then create advertisements (videos, brochures, performances, etc.) for their new product(s) or application(s), and present to the judges for review similar to a “Shark Tank” environment.

Students act as mining engineers and simulate ore mining production by using chocolate chip cookies. They focus on the cost-benefit analysis of the chocolate ore production throughout the simulation, which helps them understand the cost of production. As students “mine” with tools such as paperclips and toothpicks, they keep records of their costs—land (cookie), equipment used, cookie size before and after production, and time spent. While the goal is to make as much profit as possible, other costs and goals are taken into consideration—as in real-world mining engineering. For example, mining engineers also consider the resulting amount of destruction to the lithosphere when deciding the best method to obtain ore. Thus, a line item for land reclamation cost is included from the beginning. A provided worksheet serves as a profit and loss statement.

Music: Inevitable - Diamond Ortiz

One way to conserve energy in a building is to use adequate insulation to help keep hot or cool air inside or outside of the structure. Inefficient heating and cooling of buildings is a leading residential and industrial source of wasteful energy use. In this activity, student groups conduct a scientific experiment to help an engineering team determine which type of insulation conserves the most energy—a comparison of newspaper, wool, aluminum foil and thin plastic. They learn about different kinds of insulation materials and that insulation prevents the transfer of heat, electricity or sound. Student teams collect data and make calculations, then compare and discuss their results. A student worksheet is provided.

Put the ‘E’ in STEM by making applied science, technology, and math come alive through engineering design and design thinking.

What do enzymes and engineering have in common? As a catalyst that creates a chemical reaction, enzymes are a unique substance that chemical engineers can learn from to create their own unique chemical designs. In this lesson, students learn about enzymes, study how enzymes work in our digestive system, and discuss enzymes are used in laundry detergents. Students relate to the idea that enzymes digest the food in the human body, and that enzymes can also be used to digest food stains on clothing.

Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines — the wedge, wheel and axle, lever, inclined plane, screw, and pulley — in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today. In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and selecting a construction site. The six simple machines are examined in more depth in subsequent lessons in this unit.

Students investigate how mountains are formed. Concepts include the composition and structure of the Earth's tectonic plates and tectonic plate boundaries, with an emphasis on plate convergence as it relates to mountain formation. Students learn that geotechnical engineers design technologies to measure movement of tectonic plates and mountain formation, as well as design to alter the mountain environment to create safe and dependable roadways and tunnels.

Students explore the basics of DC circuits, analyzing the light from light bulbs when connected in series and parallel circuits. Ohm's law and the equation for power dissipated by a circuit are the two primary equations used to explore circuits connected in series and parallel. Students measure and see the effect of power dissipation from the light bulbs. Kirchhoff's voltage law is used to show how two resistor elements add in series, while Kirchhoff's current law is used to explain how two resistor elements add when in parallel. Students also learn how electrical engineers apply this knowledge to solve problems. Power dissipation is particularly important with the introduction of LED bulbs and claims of energy efficiency, and understanding how power dissipation is calculated helps when evaluating these types of claims. This activity is designed to introduce students to the concepts needed to understand how circuits can be reduced algebraically.

After watching a short online video that recaps the enormous scale of accumulating plastic waste in our oceans, student teams are challenged to devise a method to remove the most plastic microbeads from a provided commercial personal care product—such as a facial cleanser or body wash. They brainstorm filtering methods ideas and design their own specific procedures that use teacher-provided supplies (coffee filters, funnels, plastic syringes, vinyl tubing, water, plastic bags) to extract the microplastics as efficiently as possible. The research and development student teams compare the final masses of their extracted microbeads to see which filter solutions worked best. Students suggest possible future improvements to their filter designs.

Students construct three-dimensional models of water catchment basins using everyday objects to form hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human activities. Students discuss how engineers design structures that impact water collection, as well as systems that clean and distribute water.

Students engineer a working pair of shin guards for soccer or similar contact sport from everyday materials. Since many factors go into the design of a shin guard, students follow the Engineering Design Process to create a prototype. Along the way, students keep a notebook documenting each stage of the process and reflect on what they learned during the design.

Students design their own logos, pictures or other graphic images and then use handheld GPS receivers to map them out. They write out the image on a field or playground, walk the route, and log GPS data. Displaying the collected data on the GPS receiver screen results in the finished artwork. The process requires students to use geometry, sketch, measure distances and make scaling calculations, and familiarizes them with technological devices. A student worksheet is provided.
