Students experience firsthand one of the most common water treatment types in the industry today, flocculants. They learn how the amount of suspended solids in water is measured using the basic properties of matter and light. In addition they learn about the types of solids that can be found in water and the reasons that some are easier to remove than others. Encompassing the concepts of force and motion, attraction and repulsion of charged particles, and properties of matter, during the associated activity students see scientific concepts they already understand through the eyes of engineers who apply them to the removal of solids from water via chemical flocculants.

Students will be given one hydrogen generator and one oxygen generator. They will first be asked to balance the chemical equation for the combustion of hydrogen gas in the presence of oxygen. Next, they will analyze what the equation really means. Two hypotheses are given, based on what one might predict upon analyzing the presented chemical equation. Once students have thought about the process, they will be walked through the experiment and shown how to collect the gas in different ratios. The students will then be free to go through the steps of trial and error to determine the ideal ratio for combustion. Results will be qualitatively recorded on a scale of 0 through 5 for both volume of explosion and kick generated by explosion. Once completed, students must use their collected results to see if the hypotheses were correct and see how their results match the theoretical equation. This exercise exposes students to a potentially new alternative energy, hydrogen gas. While hydrogen most likely will be used as the input for fuel cells (that have no combustion) it has been used in rocket engines (where there is tremendous combustion occurring).

Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.

Students learn about the heart and its role at the center of the human cardiovascular system. In the associated activity, students play out a scenario in which they are biomedical engineers asked to design artificial hearts. They learn about the path of blood flow through the heart and use that knowledge to evaluate designs of artificial hearts on the market.

Students are presented with a scenario in which they are biomedical engineers asked to design artificial hearts. Using the engineering design process to guide the lesson, the problem is established and students brainstorm to list everything they would need to know about the heart in order to create a complete mechanical replacement (size, how it functions, path of blood etc.). Then they research to learn the information and organize it through various activities. They research artificial heart models that have already been used and rate their performance in clinical trials. Finally, they analyze the data to identify the artificial heart features and properties they think work best and document their findings in essay form.
