Experiment 1
Using the Scientific Method: What are the mystery powders?

Purpose/Hypothesis

In this experiment, you will begin with three mystery powders and ask yourself, "What are these powders?" Then you will gather information from a chart that shows how three kinds of powder react when mixed with water, iodine, and vinegar. Next, you will hypothesize the identity of each mystery powder. Then you will test how each powder reacts with water, iodine, and vinegar. You will compare your results with the chart and draw a conclusion about the identity of each powder. Then you will know whether your hypothesis was correct.
