Teaching Earth's Systems
with Spin & Find
Original portfolio sample: a teacher facilitation guide for my interactive game "Spin & Find." Created to demonstrate curriculum-design capability. Not affiliated with or produced for any employer or institution. Standards frameworks are named; every specific code is left as a marked placeholder to be confirmed against the current published standards before classroom use.
1 · Module Overview
Grade-band justification. Grades 5–8 sit at the sweet spot: students have the vocabulary to name continents and oceans, and are ready to move from locating places to reasoning about the Earth systems those places reveal, freshwater storage, plate tectonics, climate extremes.
By the end, students can locate all seven continents and five oceans, and use each region's real feature as evidence to explain how Earth's systems store water, move continents, and produce climate extremes.
2 · Learning Objectives
Locate & identify all 7 continents and 5 oceans on a globe.
Describe one defining physical feature of each region using the game's fact set.
Relate the Great Lakes and Amazon facts to how Earth stores and moves fresh water.
Explain & connect the Mid-Atlantic Ridge fact to plate tectonics.
Objectives ladder from lower-order (locate / identify / describe) to higher-order Bloom verbs (relate / explain / connect).
3 · Standards Alignment
| Objective | Framework | How it aligns | Code |
|---|---|---|---|
| Obj. 1–2 · Locate & describe | National Geography Standards | Uses mental maps and spatial reasoning to organize information about places and physical features. | Nat'l Geo Std. 2 |
| Obj. 3 · Freshwater systems | NGSS SEP: Analyzing & Interpreting Data; hydrosphere | Students use real place-facts as data to reason about where Earth's fresh water is stored and how it moves. | MS-ESS2-4 |
| Obj. 4 · Plate tectonics | NGSS SEP: Obtaining, Evaluating & Communicating Info; geosphere | The Mid-Atlantic Ridge spreading fact becomes evidence for a moving, changing geosphere. | MS-ESS2-3 |
| Cross-cutting · Communicating findings | Common Core: literacy in science | The capture sheet and CER task require citing evidence in writing to support a scientific claim. | WHST.6-8.1 |
4 · How the Game Supports the Learning Science
The game re-surfaces places right as students are about to forget them, and recalling a fact strengthens it more than re-reading.
Tell students: "Getting it slightly wrong and correcting it is how learning sticks, don't avoid the hard ones."
Explore builds the map; Find It and Name It test the same knowledge two different ways, so students can't fake mastery by repeating one task.
Tell students: "Start in Explore. Switch modes often: if you can only do it one way, you don't know it yet."
Every miss shows the correct location and the direction and distance from the guess, teaching a corrected map, not just marking a fail.
Tell students: "Read the feedback on a wrong answer, that's the part that teaches you."
5 · Lesson Flow
inquiry hook
Open with a question that turns place-naming into science: "Where is Earth's fresh water actually stored?" Students guess, then meet three clues, Antarctica holds ~70% of Earth's fresh water as ice up to ~4.8 km thick; the Great Lakes hold ~21% of the surface fresh water in five connected basins; the Amazon carries about a fifth of all river water reaching the oceans. The hook reframes the globe as an Earth-systems dataset.
practice
Students play Explore mode first (5–8 min) to build the mental map, then move to Find It and Name It for retrieval practice. Individual for the first pass, then pairs so students explain their reasoning aloud. The teacher monitors the Mastery Map to see which regions the class is missing and pulls the group back together to address common gaps.
Close by grouping regions under Earth-system themes rather than by name, a discussion or sorting task:
Antarctica, Great Lakes, Amazon, Indian Ocean monsoon
Atlantic (Mid-Atlantic Ridge), Asia (Everest / Dead Sea), Pacific (Challenger Deep)
Antarctica (−89.2 °C), Africa (Sahara), Southern Ocean sea ice
6 · Student-Facing Materials
What do the world's places tell us about how Earth's systems work, and how they're still changing?
As you play, record 2–3 place facts that surprised you, then answer:
"The Atlantic widens about 2.5 cm per year. What does that tell you about the ocean floor, and about the continents on either side of it?"
Scaffolded reasoning: connect a rate of change to a mechanism (seafloor spreading / moving plates), not just recall a number.
"Asia holds both Earth's highest land point (Everest, 8,849 m) and one of its lowest (the Dead Sea shore, −430 m). What Earth processes could produce such extremes so close together? Propose an explanation and note what evidence would test it."
7 · Assessment
"Name one continent or ocean and the Earth system its main feature belongs to (water, tectonics, or climate), and say why." Directly checks Objectives 3–4.
"Which continent's or ocean's feature best shows Earth's systems changing over time? Make a claim, support it with evidence from the game's facts, and explain your reasoning."
8 · Differentiation & Accessibility
Provide the fact set as a picture-and-phrase reference card; pre-fill the capture sheet's first row as a model. Use Explore mode longer before graded modes.
Assign the Asia-extremes extension and Streak mode; ask them to add a region to one Earth-system group and defend it.
The game is fully usable keyboard-only and by screen-reader users, live audio announcements read out prompts, results, and the same direction-and-distance feedback sighted players see, and a reduced-motion option stops the globe from spinning. Pair a screen-reader user with a partner for the map-sorting discussion, not for gameplay, they can play independently.
9 · Facilitator Tips & Misconceptions
Clarify: it was officially recognized as the fifth ocean in 2021, ringing Antarctica. A good example that science classifications get updated.
Use the Atlantic's ~2.5 cm/year widening as concrete evidence that plates, and the continents on them, are moving right now, just slowly.
The synthesis grouping shows features cross the land/water line, the Mid-Atlantic Ridge is under an ocean but is a tectonic story shared with the continents.
Reframe it as Earth's largest freshwater reservoir, ~70% of the planet's fresh water, locked as ice.
