Is runoff water from a parking lot or business area trickling into the water and adding unclean elements and materials to the water? A Spot-the-difference activity is a puzzle that can help you become an experienced observer just like these STEM professionals. In this kind of puzzle, you are given two photographs or illustrations. At first glance, they might appear very similar, with the drawing and outline looking identical. With closer inspection, you will see that [...]
