How Can you Study Objects That Are Not Visible?
Make and record observations about the contents of two sealed bags. Use your senses of touch, smell, and hearing to help you make your observations.
Predicting Based on your observations, make a prediction about what objects could be in each bag. Decide whether there is a single object or more than one object in each bag.
Your teacher will list on the chalkboard all of the predictions from the class.
Inferring What evidence did you use to predict what objects were in the bags and how many objects were in the bags?
Evaluating and Revising Record one of the predictions listed that fits your observations as well as or better than your own prediction.
Designing Experiments Propose an experiment that would test the prediction.
