13. Descriptive Investigation
Observing animal behaviors is a common example of descriptive investigations

14. Mystery Object pg. 7
You are explorers from another galaxy. You have landed in a remote area of this planet. As soon as you leave your space ship, you find a number of these objects scattered on the ground. You have never seen anything like them and are not sure what they are. Your mission is to study the object as carefully as you can, making notes and asking questions on your observation sheet. Then, write a detailed description to beam back to your high commander. Be careful not to cut or damage the object in any way. You should use as many of your senses as possible and any instrument available to you that will not damage the object. Each member of your crew should come up with his or her own notes and description, but you may compare and discuss if you like. If questions about the object come up, write them down. You have 10 minutes to complete your description

Jane Goodall began studying Chimpanzee’s in the 1960’s. Jane moved to Africa and began making close observations of Chimpanzees in the wild and in captivity. Because of her investigations we now know that chimpanzees are meat eaters, use tools, and hunt Capuchin monkeys for food.
