Types of Natural Resources

Students learn best when they move from abstract definitions to concrete decisions about real resources. Sorting, analyzing cases, and discussing trade-offs turn the topic of natural resources into something they can visualize and debate, which builds lasting understanding.

Sorting Activity: Renewable or Non-Renewable?

Provide groups with a card set of 20 resources including obvious cases (coal, solar) and ambiguous ones (wood, groundwater, lithium). Groups classify each card and must write one sentence justifying each decision. After sorting, the class discusses the ambiguous cases and refines the criteria for classification, discovering that replenishment rate relative to use rate is the key variable.

Differentiate between renewable and non-renewable natural resources.

Facilitation Tip

For the sorting activity, give each pair a set of resource cards and two colored trays labeled ‘Renewable’ and ‘Non-renewable’ to create a hands-on sorting station.

What to look for

Provide students with a list of 10 natural resources (e.g., coal, sunlight, timber, natural gas, salmon, diamonds, wind, fertile soil, groundwater, oil). Ask them to sort these into three columns: Renewable, Non-renewable, and Conditionally Renewable. Then, ask them to select one resource from each category and write one sentence explaining their classification.

Activity 02

• Case Study Analysis
• 40 min · Small Groups

Case Study Analysis: Energy Mix by State

Groups each receive a different US state's energy profile (Texas, California, West Virginia, Iowa, Hawaii) and analyze the proportion of renewable vs. non-renewable sources, the natural resources available in that region, and the trade-offs of the current mix. Groups present findings and the class builds a national picture of resource geography.

Analyze the importance of various natural resources for human society.

Facilitation Tip

During the case study analysis, assign each group a different state so they can compare regional energy mixes and resource dependencies.

What to look for

Pose the question: 'Imagine our town relies heavily on a specific non-renewable resource, like coal for electricity. What are two potential long-term problems we might face if we continue using it without a plan for alternatives, and what are two steps we could take now to prepare for the future?'

Activity 03

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: What Counts as Sustainable?

Students read a short scenario describing a fishing community that harvests at the maximum sustainable yield each year. Individually they decide whether this use is sustainable and write a justification. Pairs compare reasoning, then the class uses the example to refine the definition of sustainable resource management beyond simply using renewables.

Justify the need for sustainable management of Earth's resources.

Facilitation Tip

In the Think-Pair-Share, provide a short reading excerpt about a fishery collapse before the discussion to ground the conversation in a real example.

What to look for

Students write a short paragraph (3-4 sentences) explaining why managing freshwater resources sustainably is important, even though water is considered renewable. They should include at least one specific challenge related to freshwater availability.

A few notes on teaching this unit

Teach this topic by first addressing the binary trap many students fall into. Use examples like fish stocks and clean water to show that ‘renewable’ does not mean ‘unlimited.’ Avoid starting with lectures on definitions; instead, let students discover the nuances through structured activities. Research shows that when students confront edge cases early, their understanding of core concepts strengthens.

Students will confidently classify resources into renewable, non-renewable, and conditionally renewable categories and explain why some renewables still require careful management. They will also connect local energy choices to global resource realities.

Watch Out for These Misconceptions

• During Sorting Activity: Renewable or Non-Renewable?, watch for students who automatically place freshwater, topsoil, and fish in the renewable column without considering depletion.

  During the sorting activity, have students examine the edge-case cards more closely and ask them to justify their placement using evidence from the resource cards or prior knowledge.

• During Case Study Analysis: Energy Mix by State, watch for students who assume switching entirely to renewable energy eliminates all resource concerns.

  During the case study discussion, point out the mineral requirements for wind turbines and solar panels and ask students to revisit their initial assumptions about sustainability.
