Where does this matter?
Identifying variables helps turn a broad curiosity into a testable classroom question.
What should you keep in mind?
Plant growth also depends on water, seed quality, and temperature; hold them steady in a real test.

YOUR TASK
Which measurement responds when the test condition changes?
READ THE BENCH CARD
Separate the assigned factor from the measured response
Read the scenario, then identify what the investigator sets and what the investigator measures. Plant growth also depends on water, seed quality, and temperature; hold them steady in a real test.

INVESTIGATION CARD A-04Students place bean plants at three lamp distances and measure their height after 14 days.
WHAT TO TAKE AWAY
The independent variable is deliberately changed; the dependent variable is measured as the response.
WHERE THIS IS USED
Identifying variables helps turn a broad curiosity into a testable classroom question.
MODEL LIMIT Plant growth also depends on water, seed quality, and temperature; hold them steady in a real test. The activities on this page do not store classroom measurements.
