Why are living things different from one another? This unit on genetics starts out with students noticing and wondering about photos of two cattle, one of whom has significantly more muscle than the other. Students figure out how muscles typically develop as a result of environmental factors such as exercise and diet. Then, they work with cattle pedigrees, including data about chromosomes and proteins, to figure out genetic factors that influence the heavily muscled phenotype and explore selective breeding in cattle.
This unit is part of the OpenSciEd core instructional materials for middle school.

The coral reefs of the South Pacific island nation of Vanuatu are the backbone of the island's environmental and economic health. Today they face destruction from a silent predator that can rapidly decimate an entire reef. In this video, students learn about how a starfish is destroying the coral reefs of Vanuatu and how the islanders are adapting.

In this video, an entrepreneur is finding new ways to manage the invasive Asian carp problem in the Mississippi and Ohio rivers. Once introduced to help mitigate an algae problem, the carp became invasive. This video highlights how the local community has adapted to the issue, including how they have gained ideas about how to utilize the carp from other cultures to help mitigate the issue.

This exercise should be used after you think students know what AFM diagrams are and how they work. This is sort of a quiz -- to see if they can properly interpret the diagrams. There is no point moving on to real projects that involve AFM diagrams if the students don't understand the basics.

The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life. Starting with the discovery and history of ATP, this lesson will walk the students through 8 segments (outlined below) interspersed by 7 in-class challenge questions and activities, to the final step of ATP production by the ATP synthase, an amazing molecular machine. A basic understanding of the components and subcellular organization (e.g. organelles, membranes, etc.) and chemical foundation (e.g. biomolecules, chemical equilibrium, biochemical energetics, etc.) of a eukaryotic cell is a desired prerequisite, but it is not a must. Through interactive in-class activities, this lesson is designed to spark the students’ interest in biochemistry and human biology as a whole, but could serve as an introductory lesson to teaching advanced concepts of metabolism and bioenergetics in high school depending on the local science curriculum. No supplies or materials are needed.

For students interested in studying biomechanical engineering, especially in the field of surgery, this lesson serves as an anatomy and physiology primer of the abdominopelvic cavity. Students are introduced to the abdominopelvic cavity—a region of the body that is the focus of laparoscopic surgery—as well as the benefits and drawbacks of laparoscopic surgery. Understanding the abdominopelvic environment and laparoscopic surgery is critical for biomechanical engineers who design laparoscopic surgical tools.

In this activity, students work with paleoclimate proxy data (d18O, CH4, CO2)from the Byrd and GISP2 ice cores to investigate millennial-scale climate changes during the Last Glacial/Deglacial time periods. Students must prepare a publication quality plot of the data and answer several questions about the similarities and differences between the time-series (north-south phasing, amplitude, symmetry) and use this information to assess the bipolar see-saw mechanism for abrupt climate changes. Students are encouraged to read two journal articles for more information and to synthesize their results with other information from lectures and earlier readings.

This is a computer-based activity in which students retrieve data from websites maintained by the US Geological Survey (USGS) and the National Weather Service (NWS), and then use that data to test different hypotheses regarding streamflow and precipitation. Students import data from web sites into a spreadsheet program where they can construct scatter plots and perform simple statistical tests. The activity has two components, the first focusing on relations between streamflow and drainage basin characteristics (drainage area, slope, precipitation), the second focusing on trends in annual precipitation at two locations in the USA: Burlington, VT, and Boulder, CO. As part of the second component, students conduct a statistical test to determine if the long-term trends in precipitation are significant.

Intended Audience: This activity was used for an introductory Geochemistry class, which contained students from sophomore level to master's students. We took the trip in mid-October, about as late as possible in Vermont, after they had gained some previous field experience and lab work in addition to an in introduction to these principles in class.

Using the article "Stop Raising Awareness Already" by Cristiano and Neimand and a six-step template, students create a plan to show how they apply the knowledge learned throughout the term to make a broader impact. The students are asked to very narrowly choose a single action they want a group of stakeholders to take and develop a multiple-step plan to accomplish the action. The students are required to select and justify a targeted stakeholder, develop an action, identify a messenger that can influence their targeted stakeholder to take the action, develop a sticky message relating the "ask" to the goal of the campaign, and document their key assumptions imbedded in their action plan.

This assignment is a 10-hour, out-of-class project where each student designs and carries out an action plan to enhance sustainability. Students select from a large suite of alternative actions, most of which can be quantified for reductions in CO2 and energy consumption, as well as in dollar savings.
