1. Divide into groups of 4. Place your ocean (paper plate) into the center of the table. Your teacher will stock with 4
different species fish (colored marshmallows).
2. Each fisherperson gets a napkin, two straws, a piece of tape. Create a net by attaching a 6-7 cm length of tape
between two straws. You will the tape to pick up fish (marshmallows).
3. Use a paper towel for your boat.
4. You will fish for 4 species of fish.
a. _______________ are worth \$3
b. _______________ are worth \$5
c. _______________ are worth \$5
d. _______________ are worth \$10
5. To gather fish, use the tape to pick them up out of the ocean and place in your boat. NO FINGERS in the ocean,
but you can use fingers to take fish off the tape in your boat.
6. You will fish for 30 seconds as your teacher tells you to start and stop.
7. At the end of each season, you will fill out the tally sheet (data).
Rules of the game:
●
●
●
●
●
●
You all belong to the same village, but will fish as an individual. You are competing with the other people in your
village (group).
You will fish in your ocean for 4 seasons/years.
Each fishing season lasts 30 seconds.
You must earn at least \$5 each season to stay in business or survive.
At the end of each season, the fish left in the ocean will reproduce. Two fish of the same species will create two
more fish. (Fish mate in pairs). Your teacher will come and re-stock with babies between each season.
The person with the most \$ at the end of the game earns extra credit.

1. Describe the state of your ocean after the first round and the third round:
have a unified strategy for your ocean? Explain.
3. What rules did you make OR what rules should you have made as a group to be able to continue fishing year
after year? Be specific.
4. Did the village’s total income increase or decrease over time? Why?
5. Mathematically, what is the best strategy for making the most money over many years?
6. What kind of rules would you make if you were a policymaker at the Fish and Wildlife Service in the US in charge
of making sure the fishing industry didn’t run out of crabs, fish, lobster etc.? (Think about numbers, sizes,
females, etc.)
7. How would you enforce your rules?
8. Think about it: What other shared resources besides ocean fish would face the same issues as in this game?
Write a Claim about how shared resources can be depleted and how to sustainably manage them.

Discuss your local lake, ocean, or river fishing regulations. For Castaic Lake go to:

What happens when people violate fishing regulations?
9. What did this young fishermen do wrong?

11. What was the limit per day?

13. How much was his fine?
Oceans are considered “commons”—resources that we own together as citizens of the world or in a certain nation,
state, or community. The “Tragedy of the Commons” was an essay written by Garrett Hardin explaining how human
nature leads to overexploitation without rules and regulations. His study focused on open grazing land.
11. Which “commons” were first discussed as being overused over a hundred years ago in Great Britain?
12. At minute 2:30: What happens when an individual puts their well-being over the common good? What are the
results?
13. How has overuse of antibiotics by the meat industry affected all of us?
14. How have humans solved some of these problems?
What are some other examples of commons listed in this video?
15.

Summarize the concept of Tragedy of the Commons and the solution in 2-3 complex sentences.

What are some parts of nature that we all share?
What are some parts of the community that we all share?
Students write and then share. Don’t correct them if they’re wrong and share out private resources such as food, gas,
homes etc.
You can go back and discuss incorrect answers at the end when they realize that a commons is about shared, public
resources.

8. Divide into groups of 4. Place your ocean (paper plate) into the center of the table. Your teacher will stock with 4
different species fish (colored marshmallows).
Stock each plate with 4-6 of each color of mini-marshmallow.
9. Each fisherperson gets a napkin, two straws, a piece of tape. Create a net by attaching a 6-7 cm length of tape
between two straws. You will the tape to pick up fish (marshmallows).
10. Use a paper towel for your boat.
11. You will fish for 4 species of fish. Have the kids fill in the colors-depends on which colors you have in the minimarshmallow bag.
12.
a. _______________ are worth \$3
b. _______________ are worth \$5
c. _______________ are worth \$5
d. _______________ are worth \$10
13. To gather fish, use the tape to pick them up out of the ocean and place in your boat. NO FINGERS in the ocean,

15. At the end of each season, you will fill out the tally sheet (data).

The person with the most \$ at the end of the game earns extra credit.
After each round, go around and re-stock 2 fish for every 2-fish left of each color. Two different species (colors) can’t
mate and make babies.
At the end of the 1st round, many groups may have depleted their oceans, because they weren’t listening to the rules
very well. So, you may choose to let them “throwback” some fish from their boats for this round. This allows them to
negotiate with each other and strategize. This also allows them to continue with the game and figure out the concept.
I explain to kids on the 4th round that they can just “go for it” and fish for all the marshmallows even though in real life
they would need to sustain their ocean indefinitely.

11. Describe the state of your ocean after the first round and the third round:
have a unified strategy for your ocean? Explain.
13. What rules did you make OR what rules should you have made as a group to be able to continue fishing year

15. Mathematically, what is the best strategy for making the most money over many years?
16. What kind of rules would you make if you were a policymaker at the Fish and Wildlife Service in the US in charge
of making sure the fishing industry didn’t run out of crabs, fish, lobster etc.? (Think about numbers, sizes,
females, etc.)
Students should come up with answers such as limits or quotas, only catching females, size limits etc. Ask kids if
they’ve ever watched “Deadliest Catch” and reference their quotas, size limits and only males. Ask kids what
the limits are at the local lakes-you may have 1-2 kids who fish locally.
StrategicScience
17. How would you enforce your rules?
18. Think about it: What other shared resources besides ocean fish would face the same issues as in this game?
Write a Claim about how shared resources can be depleted and how to sustainably manage them.
This is the time in a learning cycle that you check for understanding. Go around to each group and quickly read the
statements. Clear misconceptions.
Students may struggle with this task at first, but will get used to it later. Be careful not to give away too much
information. The more that they can struggle with and then reason out themselves, the better they retain and
understand the information.

Evaluate
Summarize the concept of Tragedy of the Commons and the solution in 2-3 complex sentences.
Students should practice the skill of succinctly writing down a concept with detail.
Ask students to read aloud their statements. Clear up any misconceptions. Ask them to look at the beginning of the
lab—the Engage section. Have them correct their answers.
Remember, a “commons’ is something that is shared. Parks, Libraries, Air quality, public lakes, Public forests (national
forests), water supply (sort of). There are private sources of water and public sources of water. The West coast has
water rights, but if a city owns certain water rights, they manage it for the common good so it’s a commons. A private
well is not a commons.
Kids also need to know to write National Forests instead of just “forests” as a lot of logging is done on private land.
