My son is participating in a home school science fair this Thursday. Originally he was going to do an experiment about ant pheromones, but the ants didn't want to participate. There were a lot of tears because right now he Loves ants. I quickly found a dog experiment to do, since he also Loves dogs.
His experiment was, "what color can dogs see best?" His hypothesis - "I think dogs will see red best because my dog notices me more when I wear red."
