Using the Scientific Method in your Science Fair Project Mandy Padgett Heritage Christian School

Let’s Learn about the Scientific Method!!  Question Hypothesis Prediction Testing Results

Question • The question you ask must have a concrete answer that can be found by conducting an experiment. Why do highway trucks pour sand on icy roads in the winter? Return

Hypothesis • A testable explanation that answers your question. I know that salt is used to melt ice and I think that sand is used for the same reason. Return

Prediction • If your hypothesis is true, what will happen when you perform your experiment? If my hypothesis is true, an ice cube with sand on it will melt faster than a bare ice cube. Return

Testing • List the materials you use and the steps for the experiment. • Show the data you collect. Materials: Sand, ice cube, and a watch Steps: I sprinkled sand on one ice cube and left the other bare. I timed how long it took for each ice cube to melt. Data: Each cube took one hour to melt. Return

Results • What happened when you performed your experiment? My hypothesis was wrong because the sanded ice didn’t melt faster. They must use sand for a different reason. Return
