Research Process
Big Idea
Natural filtration of water.
Synthesizing and Classification Cu Nanoparticles
Engineering Design Process
Samples of copper carbonate with varying amounts of PVA.
The Hook: Lost in the Wild
Copper (Cu) nanoparticles are synthesized by pumping copper chloride, reducing agents (carbonate and iodide), and polyvinyl acid (PVA) into a common beaker for mixing.
Lost in the wild.
Need food and water to live.
Water must be clean to drink.
Resources only found in nature.
