Parent presentation on Water

Cameron's dad (Cameron is in Mrs. Sathyaraj's class) came in to school to tell all of the 4th graders about a couple of ways companies are working to help provide clean drinking water to people around the world.
One example was made by P&G. It was actually made by mistake when they were trying to make  effective laundry soap in cold water. Small water purification packets can collect the dirt and particles in water and make them sink to the bottom of a 1 liter bucket in just 10 minutes.
The other example was a project his coworker started as a contest entry. She made a business plan connecting UV water filtration methods, with solar rechargeable batteries, to be connected with coca-cola's distribution so clean water became a wearable device.
