Invention to Clean Oceans

identify the problem

For this challenge, you will build a prototype. Marine or ocean pollution is pollution in the sea. It is a form of water pollution. Most ocean pollution comes from land. Fertilizer from lawns and farms, motor oil, and sewage are washed into local streams and rivers, where they may eventually flow into the ocean. Plastics and trash also end up in the ocean in similar ways. Approximately 80% of ocean pollution starts from land!

Scientists think that 8.8 million tons of plastic winds up in the ocean every year—that’s as if you stacked up five plastic grocery bags full of trash on top of each other on every foot of coastline in the world.Over 700 species of marine animals have been reported to have eaten or been entangled in plastic. Scientists think that the amount of plastic in the ocean might triple by 2050—and that would mean seriously bad news for the ocean and the creatures that live there.

ocean pollution facts

01. More plastic than fish! 8 million metric tons of plastic gets dumped into the ocean each year.
02. There’s so much junk at sea, the debris has formed giant garbage patches. There are five of them around the world, and the largest — the Great Pacific Garbage Patch — includes an estimated 1.8 trillion pieces of trash and covers an area twice the size of Texas.
03. 70 percent of ocean garbage sinks to the seafloor.
04. Plastic and trash isn’t the only type of pollution – overuse of fertilizers that end up in the ocean create hazardous conditions for wildlife.

design a solution

01. Generate an idea. What invention would help clean up the oceans? How would it work? What would it be made out of? Checkout’s lesson resources for this activity.  
02. Design and build a prototype. Build your invention! In most cases you will have to create a prototype – a smaller version of your invention that helps you test, share, explain your invention. Remember – It’s ok if it is not a working prototype.
03. Share your idea. Film a short (Max 2 min video) pitch of your invention. Include details like who is it for, what problem does it solve, etc. Have fun! Upload/share your video to twitter, facebook or Instagram. Don't forget to tag us!
