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

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.
