As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions. Many sports and games, such as baseball and ping-pong, illustrate the ideas of momentum and collisions. Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.

As a class, students use a low-cost air quality monitor (a rentable “Pod”) to measure the emissions from different vehicles. By applying the knowledge about combustion chemistry that they gain during the pre-activity reading (or lecture presentation, alternatively), students predict how the emissions from various vehicles will differ in terms of pollutants (CO2, VOCs and NO2), and explain why. After data collection, students examine the time series plots as a class—a chance to interpret the results and compare them to their predictions. Short online videos and a current event article help to highlight the real-world necessity of understanding and improving vehicle emissions. Numerous student handouts are provided. The activity content may be presented independently of its unit and without using an air quality monitor by analyzing provided sample data.

AE 868 is an elective for the Solar Energy Option within the online Intercollege Master of Professional Studies degree program in Renewable Energy and Sustainability Systems (iMPS-RESS). It examines the theories and design practices of solar electric systems in the context of utility and commercial-scale applications. As AE 868 is intended for graduate students and professionals with interests in the procurement and delivery of commercial photovoltaic (PV) systems, an important goal of the course is to equip solar professionals with skills to follow the impact of hardware trends in industry on feasibility, design, and commissioning of such systems. This goal is reinforced with authentic assessments in the form of a sample of real problems that solar professionals solve in their line of work with examples of resources they access for this purpose and several case studies on design and construction of PV systems. Students will learn how to design solar electric systems as well as the processes required for permitting, construction, and commissioning of solar electric systems.

In this activity, students use climate data to develop a simple graph of how climate has changed over time and then present the result in a blog, emphasizing effective science communication.
This activity explores how the topic of climate change is represented in …
This activity explores how the topic of climate change is represented in various forms of writing, from scholarly articles to opinion pieces and works of fiction. While the content does not emphasize climate science itself, it instead allows students to focus on how the science is being portrayed.

Students groups create scientific research posters to professionally present the results of their AQ-IQ research projects, which serves as a conclusion to the unit. (This activity is also suitable to be conducted independently from its unit—for students to make posters for any type of project they have completed.) First, students critically examine example posters to gain an understanding of what they contain and how they can be made most effective for viewers. Then they are prompted to analyze and interpret their data, including what statistics and plots to use in their posters. Finally, groups are given a guide that aids them in making their posters by suggesting all the key components one would find in any research paper or presentation. This activity is suitable for presenting final project posters to classmates or to a wider audience in a symposium or expo environment. In addition to the poster-making guide, three worksheets, six example posters, a rubric and a post-unit survey are provided.

In this activity, students collect data and analyze the cost of using energy in their homes and investigate one method of reducing energy use. This activity provides educators and students with the means to connect 'energy use consequences' and 'climate change causes.' Through examining home energy use and calculating both pollution caused by the generation of electricity and potential savings, students can internalize these issues and share information with their families.

This lab activity is designed to allow students to experience what an increase in mechanical advantage means. Students determine the mechanical advantage of three pulley set-ups. Students also measure the work input and output, then calculate the efficiency. Finally, students determine the relationship between the mechanical advantage and the efficiency of the pulleys.
