Indentifiyng species is the answer
Did a bit of research, found a cool one.
Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or foot when hearing, seeing, or kicking something? Which side do people use the most? In this science project, you will get to find out!
