Acid Mine Drainage Field-Lab Experience Round 1
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this field-based exercise, students were given a tour of an abandoned mine site and asked to utilize a set of field measurements to describe the spatial details of metal transport. This drew on previous experience with field measurements and prompted them to work together to solve an observed chemical evolution of a contaminated brook. The exercise is an excellent example for students to bring together acid-base chemistry, redox chemistry, and thermodynamic concepts together to describe a reasonably complex system. The field component was completed in a full day, but we will be expanding this next fall for a 2 day exercise (weekend). The exercise was coupled with subsequent labs to complete analysis of the water samples and accomplish speciation calculations using PHREEQCI.

Co-evolution of Life and Minerals

Based on the 2010 Scientific American paper by Hazen, and the more technical 2008 paper of Hazen et al, both of which explore the effect of the biosphere on the tremendous number of mineral species that occur on Earth compared to the lesser number we believe we are seeing on other planets. This tackles the idea of mineralogy/geochemistry evolving over time as do biological systems, rather than being a static system with no hysteresis or temporal aspect to it. Students work in small groups to decide which groups of minerals have been most affected by a variety of biological influences, and how. Then the class as a whole compares their conclusions group by group.

Introduction to Carbonate Equilibrium
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The activity asks students to make observations about what occurs when two effervescent antacid tablets are placed into a beaker of water. The Students work together in groups. There are three parts to the activity. In the first part, the tablets are dropped into tap water and student groups (2-4 students) must complete a series of question sheets (one per group) that guide them through thinking about the event. In the second part, a presentation on chemical equilibrium for the carbonate system is given. The starting point is the answers received in the first part. Basic chemical reactions for the carbonate system are presented including equilibrium expressions for each reaction and discussion about open and closed systems. At the end of class, a handout is given to the students. In the third part, three beakers (acidic, neutral and basic solutions, but not indicated) are placed together and two tablets are placed into each beaker. Students are split into two groups (8-12 students) and are asked to describe why the reactions are different. Discussion follows collection of student responses in each part. Once the chemical reactions and equilibrium expressions are presented, they are involved and referenced in all discussions.

Relationship between mineral weathering and groundwater composition
Conditional Remix & Share Permitted

Rating
0.0 stars

In this pair of activities, students start by using published data to predict what will happen to groundwater composition as a consequence of chemical weathering. The data are provided in a spreadsheet (Hinman_weathering). Students are given the histograms only; both are normalized to 100 %, while one includes silica and the other does not. Students must use resources to predict how groundwater composition will change as a consequence of the observed weathering, and support those predictions using balanced chemical-weathering equations. Afterwards, they conduct a laboratory experiment in which they subject crushed rock to four types of solutions (acid solution, organic-rich solution, rainwater, and alkaline solution). The pH of each solution is measured, and subsequently adjusted after 24 and 48 hours. Solutions are sampled after 14 days. They are analyzed by ICP, and the compositions reported to students for comparison with their predictions.

Weak Acid Equilibrium
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Students are asked to calculate the pH of a weak acid aqueous solution. The problems involve a series of generic acids with assigned equilibrium constants (Ka) and total concentrations (Ct). Initially, students are required to hand calculate all problems by algebraic manipulation of the mathematical relationships of the system. The solution is a cubic equation. Through a series of assumptions, the solution is simplified. The assumptions are based on the chemistry of the system given the Ka and Ct for the problem. The problems are then graphically solved. Ultimately, the students develop an Excel worksheet to solve the problems and a Bjerrum plot to display the speciation as a function of pH.
