Carbon Footprint – Most people don’t think about the carbon footprint that they leave on the environment when they buy a product. But students at Samsel Upper Elementary School in Sayreville are not only paying attention, they are working on ways to reduce their carbon footprint. The children are looking at ways that products, food, energy consumption, and transportation impact our environment. They also have a Waste Free Lunch competition in which different grades are pitted against each other to determine who can make the least amount of waste at lunch.
