"Sack Secrets" - We did this activity last week in class as an activity to start our unit on "What is Matter". (Unfortunately, I wasn't there when we did it this year). What I do is go around my house and gather up about 15 small items that will fit into a brown paper lunch sack. I try to find a variety of things so that the students can use 4/5 of their senses to describe different properties of the matter that is in the bag. They write down different properties of the matter in the bag and then make a "hypothesis" of what they think is in their bag based on the different properties that they have listed on their data sheet. When every group has made an educated guess, I open the bags to reveal what is inside. The anticipation level is high as they find out what is actually in each mystery bag.
