Question

Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Use the drop-down menus to complete the statements.



This experiment was divided into two parts. For the first part of the experiment, the
was intentionally manipulated. This was the independent variable. The dependent variable measured was the
.

For the second part of the experiment, the
was intentionally manipulated. This was the independent variable. The dependent variable measured was the
.

Answer 1

I don’t have the Student Guide or your data, so I can’t fill those blanks for you directly. Tell me which variables you actually changed in each part of the lab (or paste the drop‑down choices), and I’ll fill the sentences exactly.

If you want to decide it yourself, here’s how to choose and some common examples.

How to identify the variables
- Independent variable = what you intentionally change between trials (the factor you manipulate).
- Dependent variable = what you measure in response to that change (the outcome or data you collect).

Example templates you can copy into the worksheet (replace bracketed text with your actual variable):

Part 1:
- “For the first part of the experiment, the [independent variable: e.g., temperature / enzyme concentration / light intensity] was intentionally manipulated. This was the independent variable. The dependent variable measured was the [dependent variable: e.g., reaction rate / absorbance / percent germination / growth].”

Part 2:
- “For the second part of the experiment, the [independent variable: e.g., pH / substrate concentration / volume of reactant] was intentionally manipulated. This was the independent variable. The dependent variable measured was the [dependent variable: e.g., reaction rate / time to completion / mass change].”

Common specific examples
- Enzyme activity lab
- Part 1: independent = enzyme concentration; dependent = rate of reaction (product formed per minute or change in absorbance).
- Part 2: independent = pH; dependent = rate of reaction.
- Plant growth lab
- Part 1: independent = light intensity; dependent = plant height (growth).
- Part 2: independent = fertilizer concentration; dependent = plant mass or height.
- Chemical reaction rate lab
- Part 1: independent = temperature; dependent = time to completion or reaction rate.
- Part 2: independent = concentration of reactant; dependent = reaction rate.

If you paste the drop‑down options or tell me what you manipulated in each part, I’ll fill the exact sentences for you.
