Which Claw Will You Make?
These examples get you started, then you can experiment and evolve your own unique design!
After you make your claw, try a Challenge!
Accordion Example
Chopsticks Example
Pincer Example
Ocean Cleanup Challenge
Design your claw to clean up the ocean!
Plastic trash is harming ocean wildlife and washing up on beaches around the world. Use your claw to complete all three stations of the challenge (you can change your design between stations).
Learn more about seaborne trash at fws.gov/refuges/features/OceansOfTrash.html
Constraints:
(rules and limits for your design)
- You must use a claw powered by hydraulic cylinders.
- You may only use claw supplies listed on Page 1
- You have _____ minutes to complete each station of the challenge
- You have _____ minutes to change designs between each station
One claw can’t do it all (at least not well), so change your claw design for each part! The engineering design process is never done – there is no perfect design.
Station 1: Garbage Patch
Huge amounts of trash are floating in the ocean. Load trash into the container
as fast as possible.
Criteria:
+5 points for every piece of “trash”
+1 point for every extra second left on the clock
You can use anything almost for “trash.” Candy, office supplies, toys, recyclables, etc.
Station 2: Load the Barge
Containers of trash must be shipped to land for processing. Stack containers
on the barge as fast as possible.
Criteria:
+5 points for each “container” on the “barge”
+1 point for every extra second left on the clock
Station 3: Beach Cleanup
Pieces of trash are washing up onto beaches. Design a claw to separate the
trash from the sand without disturbing any of the wildlife.
Rice or sugar can be used as sand. Candy, fishing lures, etc. can be used for trash/wildlife.
Criteria:
+5 points for every piece of “trash”
–10 points for every piece of wildlife
+1 point for every extra second lefton the clock
