Trash day is always a popular day! For this activity, collect trash from home and bring it in for an investigative activity. The goal of the class is to determine the identity of the "neighbor" (you yourself or a neighbor that agrees to provide trash). We examine each trash item, explain what we know about that item, and then make an inference about the person based on the trash. At the end of the activity, students determine age, gender, race, occupation, hobbies, and a fun fact all based on the trash. Then, they make their case about their conclusion. The final reveal is always fun!
