SALMON - STEM Challenge
BUILD A Fish Trap Challenge
Did you know that salmon are at the heart of the Nad’uten people’s culture? Salmon are especially important because it’s the primary source of their traditional diet for thousands of years … but - they don't just catch as many salmon as they can - they're careful to make sure there will always be enough salmon for the future. One of these sustainable fishing methods has been to use fish traps.
In this STEM Challenge, we are going to design and build our very own fish trap.
Suggested Materials:
Small downed branches (already found on the ground)
Twine or string
Recycled materials
Popsicle sticks
Glue-gun
Water bottle or another fish representation
Wooden skewers
Phase 1: Research and Design
Just like the Nad’uten people, many cultures around the world use fish traps to catch fish. You can learn about the different types and how they work by doing some research. After learning about them, design your own blueprint.
Phase 2: Materials
Decide what material you want to build your trap out of. Do you want to use natural materials like branches cut from a tree, or do you want to use artificial materials, like things found in the recycling bin?
Phase 3: Begin Construction
Following your blueprint, start building your trap.
Phase 4: Time to Test
To test the trap, use an object to resemble a fish - for ours, we'll use a bottle filled with water. If your trap is smaller, use a smaller object. Place the fish in the trap and make sure it can’t shake or slip out. If the fish slips out too easily, go back again to your design and modify the trap to make it more secure.
