Students are introduced to biofuels, biological engineers, algae and how they grow …
Students are introduced to biofuels, biological engineers, algae and how they grow (photosynthesis), and what parts of algae can be used for biofuel (biomass from oils, starches, cell wall sugars). Through this lesson, plants—and specifically algae—are presented as an energy solution. Students learn that breaking apart algal cell walls enables access to oil, starch, and cell wall sugars for biofuel production. Students compare/contrast biofuels and fossil fuels. They learn about the field of biological engineering, including what biological engineers do. A 20-slide PowerPoint® presentation is provided that supports students taking notes in the Cornell format. Short pre- and post-quizzes are provided. This lesson prepares students to conduct the associated activity in which they make and then eat edible algal cell models.

In this activity, students explore the basic living requirements of algae (phytoplankton)through hands-on experience and an interactive game. Students investigate what algal biofuels are, how they are made, where they can grow, and, most importantly, why this topic should be investigated. Algal biofuels are an emerging source of renewable energy.

This set of a teacher and student guides provides instruction on a 2-3 day series of activities about Le Chateliers principle, which shows the effect of changes to conditions in an equilibrium reaction. Students work in pairs or groups to develop their concepts of equilibrium and the effects of changing the amount of reactants or products on an equilibrium system. The concepts are presented and analyzed using graphical representations, qualitative lab data, and modelling. The first part addresses the misconception that equal amounts are required for equilibrium through using a mini-activity that involves the transfer of water between beakers. The second part is a lab activity where students will see how an equilibrium system reacts to a change in concentration. The third part uses manipulatives to understand how an equilibrium operates using the mathematical equilibrium constant (Ksp) at the particulate view.

Students define and classify alloys as mixtures, while comparing and contrasting the properties of alloys to those of pure substances. Students learn that engineers investigate the structures and properties of alloys for biomedical and transportation applications. Pre- and post-assessment handouts are provided.

Acting as engineering teams, students take measurements and make calculations to determine the specific strength of various alloys and then report their data to the rest of the class. Using this class data, students write data-based recommendations to NASA regarding the best alloy to use in the construction of the engine and engine turbines for the Space Launch System that will eventually be used to transport astronauts to Mars.

Global temperatures continue to be affected by the combustion of fossil fuels …
Global temperatures continue to be affected by the combustion of fossil fuels and the subsequent release of carbon dioxide. This 3-week unit is designed to give 9th grade physical science or environmental science student an introduction to climate change, how humans are influencing it, and what efforts we can make to help limit or prevent it. Topics necessary for this unit include electricity, circuits, greenhouse gases, alternative energies, embodied energy, payback period, and life cycle assessments. This unit functions as a culminating project incorporating all of the topics listed above and challenges students to conduct research, engineer their own alternative energy solutions and prove their efficiency through calculation. Individually or in pairs students must pick an alternative energy, spend a day or more researching it, a day drawing a blueprint for it and creating a materials list, two or three days building model “power plants” to light 3 LEDs, and two to three days writing summary research papers. The quantitative analysis of their models (included in their research papers) and student’s ability to prove their models environmental superiority over fossil fuels will be weighted heavily.
