Variables and evidence — study worksheet

Name: ____________________ Date: ______________

This printable organizer accompanies the hub lesson. It is a guided study sheet, not a scored test or an official ASVAB question set.

1. Read the core idea

An independent variable is the factor intentionally changed; a dependent variable is the measured response. Keep other relevant conditions alike so they do not explain the difference. Repeated observations help distinguish a consistent pattern from an unusual result. Read graph labels and units before comparing values. A conclusion should match the evidence collected, rather than claim more than the experiment tested.

2. Trace the worked example

To compare plant growth under two light levels, use similar plants, soil, watering, and duration. Measure growth in the same units.

Write the steps or relationships that explain the result:

3. Use the method

Name the changed factor, measured response, and two controlled conditions. Then state a conclusion that the data could support.

Summarize the method in your own words, with a diagram or labeled units where useful:

4. Record a mistake to avoid

A correlation can suggest a relationship without establishing its cause.

Describe how you will recognize and correct this mistake:

5. Review after practice

Use the mixed practice check linked in the hub. Record the skill you need to revisit and your next study step.
