Question

In Part I, the independent variable, the one that is intentionally manipulated, is
.

In Part II, the independent variable changes to
.

The dependent variable, the one you measure the response in, is the same for Parts I and II. For both parts of the lab, the dependent variable is

Answer 1

I don’t have the lab sheet, so I can’t fill the exact answers. Tell me which lab or paste the procedure/Part I and Part II descriptions, and I’ll fill them in.

If you want to identify them yourself, here’s how:

- The independent variable is what you intentionally change between trials in that part of the lab.
- The dependent variable is what you measure as a response (it depends on the independent variable).
- Controlled variables are everything you keep the same.

Common examples:
- Pendulum lab: Part I independent variable = mass of the bob; Part II independent variable = length of the string; dependent variable = period (time for one oscillation).
- Hooke’s law spring: Part I independent variable = applied mass (force); Part II independent variable = spring material or spring constant (or number of coils); dependent variable = spring extension.
- Enzyme reaction: Part I independent variable = substrate concentration; Part II independent variable = temperature (or pH); dependent variable = reaction rate (e.g., product formed per minute).
- Ohm’s law: Part I independent variable = voltage; Part II independent variable = resistance; dependent variable = current.

Give me the lab details and I’ll write the exact sentences to fill the blanks.
