Investigation is happening all over the world. Some planets are getting investigated right now, but also important people from a while back like Dred Scott have been investigated. Investigation is important to help understand the past and discover a new future. Dred Scott was a slave who fought for his freedom and Rosa Parks was a woman who did not give up her seat on a bus when segregation was legal. Mars is a big mystery right now but when the mystery is solved it could become history in the future. Jupiter is a gas planet but it has some mysteries itself like the great red spot. These are just a couple of the big investigation stories of the past and the present. Investigating leads us to new discoveries and a better understanding of the world.
