Activity Option 2.1 - Batteries as an Example of Consumer Demand and Mineral Supply
- Identify the mineral resources used in rechargeable batteries.
- Describe overall trends illustrated in mineral production and mineral value (price) graphs; identify changes in trends and/or anomalous features in the graphs; and explain trends, changes over time, and anomalies in terms of mine production, demand, recycling, changes in technology, regulation, and/or population growth.
- Apply geoscientific habits of mind to interpret the complex relationships among consumers, producers, regulating agencies, and the environment in a global context by means of concept maps.
- Examine their own consumer behavior and judge the impacts of this behavior on sustainability.
Context for Use
Description and Teaching Materials
This activity requires students complete a homework assignment in preparation for class in addition to reviewing the Unit 2 Concept Map. The class begins with an overview/discussion, but most time is spent on a group activity. The instructor should save time at the end to summarize as a class.
- Go through the Unit 2 Concept Map (define "resource," "reserve") and give an example.
- Introduce the following activity and how it will be run.
This exercise works well as a small-group activity. Instructors can either collect the completed worksheets at the end of class or have students grade their own work as they move along. Expect students to spend 20 minutes on Part 1 and 20 minutes on Part 2. Part 1 includes questions about global demand, which should help link this unit of the module with Unit 1. Part 2 requires that students consult the Unit 2 Concept Map to make predictions about price and supply and then test their predictions against data.
Hand out all but the last two pages (until Part 2B) initially; allow students to check their predictions (Part 2B) only after Part 2A is complete.

Lithium and cobalt, the primary ingredients in the dominant rechargeable batteries, can be used to provide examples of mining types and concerns, including an introduction to acid mine drainage and cut-off grade (and hence segue into Unit 3) using the following materials:

Teaching Notes and Tips
- Make sure students have a copy of the Unit 2 Concept Map that they will use to complete Part 2A.
- Part 2 has two portions in which the students first make predictions (Part 2A) and then test those predictions (Part 2B). Only when students have made all their predictions should they request and be given Part 2B.
- If students are struggling with Part 2A, then the instructor should lead the class through the first couple of bullet points.
- Data for Part 2 can be found in an Excel spreadsheet linked below. Instructors can easily research more recent data and create updated graphs for this exercise.
- Students do not need to complete this entire activity in one sitting; therefore, this unit can easily be split between two class periods.
Assessments and Learning Outcomes
The learning outcomes are addressed by the activity questions as listed below:
- Identify the mineral resources used in rechargeable batteries and understand the properties that make the mineral resources useful: Homework 2, 6, and 7; Activity Questions 1, 4, and 5.
- Describe overall trends illustrated in mineral production and mineral value (price) graphs; identify changes in trends and/or anomalous features in the graphs; and explain trends, changes over time, and anomalies in terms of mine production, demand, recycling, changes in technology, regulation, and/or population growth: Activity Questions 1, 2, 3, 6, 9, and 10.
- Apply geoscientific habits of mind to interpret the complex relationships among consumers, producers, regulating agencies, and the environment in a global context by means of concept maps: Activity Question 9
- Examine their own consumer behavior and judge the impacts of this behavior on sustainability: Homework Questions 1, 3, 4, 5; Activity Questions 2, 3, and 8.
An instructor could grade the activity if the students complete it individually or in groups.Possible Exam Questions
