How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.

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.

By far most field trips in structural geology and regional tectonics do NOT take place in large urban centers with a trip focus on mitigation of hazards. What is described here is an example of the instructional and learning opportunities associated with active tectonic examination of large population centers.

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell membrane. Concentration gradient, sizes, shapes and polarity of molecules determine the method of movement through cell membranes. This activity is associated with the Test your Mettle phase of the legacy cycle.

In the minerals and products activity, students match physical products with actual mineral samples, using observable properties as well as the minerals' chemical formulas and some products' ingredient lists.

This short activity (10--15 minutes) for Unit 1 introduces students to the general relationship between economic development and resource use, and, particularly with the follow-up homework, the relationship among growing populations, increasing economic development, and natural resource extraction. The activity is intended to be completed by individuals or small groups but could also be used for a guided class discussion. This activity serves as a transition to Unit 2.

During Activity 2.2, students download, organize, and analyze geoscience data sets of sea level trends, terrestrial ice sheet trends, and intensity of tropical cyclones as well as forecast models of atmospheric CO2 and temperature trends and sea level rise. Students utilize the methods of geoscience such as systems thinking and using multiple lines of evidence to determine possible relationships and feedbacks among the data sets. Students use this data to construct their argument from evidence for a position paper in Activity 2.3.

In Activity 2.3, students make an argument from evidence to address the problem: "To what extent should we build or rebuild coastal communities?" Students work as a team to complete a graphic organizer. This task helps them organize an evidence-based position paper. Each student writes his or her own position paper.

This activity is intended to fill the first part of a class period on mining and mining impacts. It is a hands-on activity in which students, in small groups, "mine" the blueberries or chocolate chips out of a muffin. This activity helps to review the reading materials and facilitate discussion about mining and mining methods, waste, beneficiation, landscape destruction, reclamation methods, and more.
