Throughout the reflection, make sure you have a copy of the Student Guide and your data tables.



In this experiment, the
was intentionally manipulated. This was the independent variable.

The dependent variable measured was the
.

Answer 1

I don’t have your Student Guide or data tables, so I can’t fill the blanks specifically. Tell me what you changed and what you measured (or paste the table headings) and I’ll fill them in.

How to identify them:
- The independent variable (IV) is the factor you intentionally changed or controlled.
- The dependent variable (DV) is what you measured as the outcome or response.

Quick checks:
- In your data table the IV is usually the leftmost column; on a graph it’s the x-axis.
- The DV is usually the right-hand column in the table and the y-axis on a graph.

Sentence templates you can use:
- “In this experiment, the independent variable was the [what you changed].”
- “The dependent variable measured was the [what you measured].”

Examples:
- If you varied light intensity and measured plant height: “IV = light intensity; DV = plant height.”
- If you changed reactant concentration and measured time to color change: “IV = concentration; DV = reaction time.”
- If you changed the mass of a cart and measured its acceleration: “IV = mass of the cart; DV = acceleration.”

Give me the experiment details or your table headings and I’ll fill in the exact wording.
