Today in class Dr. Smirnova showed us a mystery bag filled with a bunch of stuff. She had us pass it around the class and we all had 5 seconds to touch and shake the bag to figure out what was in it. When I felt the bag I automatically thought that there was dog toy and a rattle because when I felt it, it made a squeaking noisy, and when I shook it, it rattled. I think that mystery bag activity is a great and fun way for students to create a hypothesis about what they think is in the bag. Students can use several different methods to figure out what is in the bag such as shaking the bag, feeling the bag, squeezing the bag or even smelling the bag. Aside from a dog toy and a rattle there were many other items that students could have guessed such as rocks, children's toys, balls, and so on and so forth. This activity was a lot of fun, and I can't wait to include it into my future classroom.
