Reuse or Recycle? Although both are beneficial, fourth graders recently learned that reusing is better than recycling because it saves the energy that comes with having to dismantle and re-manufacture products. It also significantly reduces wasted and pollution because it reduces the need for raw materials, saving both forests and water supplies. To put their studies to practice, students were tasked with building something meaningful (either useful or beautiful artwork) out of a minimum of 75% reused materials. Items ranged from from empty paper towel rolls and aluminum cans to plastic silverware and water bottles. The results of their green engineering project were amazing...and creative!
