### Using the Scientific Method in My Science Fair Project

Miss Jamie

OC Elementary School

Let’s Learn about the scientific method

1. Question

2. Hypothesis

3. Prediction

4. Testing

5. 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: ice cubes, sand, watch

Steps: I sprinkled sand on one ice cube and left the other bare. I timed how long it took for each cube to melt.

Data: Each ice 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.
