This activity is a great hands-on way to introduce scientific method, and it makes students "think" with their senses! This activity is easily prepared, easy to do, and easy to clean up. You will need 6 paper lunch bags or small boxes, and some random items to put in the bags/boxes. I use different random items every time I do this activity, and its usually just stuff from around my classroom or from my storage cabinet. This activity can be done as individual work, in small groups, or as a class
