In this experiment, the number of

.

Answer 1

I don’t have your Student Guide or data tables, so I can’t pick the exact items for you. To complete the sentences, identify (from your procedure/data) which quantity you deliberately changed and which quantity you counted/measured.

Use this template and fill in the two blanks:

- In this experiment, the number of _______ (the quantity you intentionally changed) was intentionally changed. This was the independent variable.
- The dependent variable measured was the number of _______ (the quantity you counted or recorded).

If it helps, here are a few concrete examples you can match to your lab:
- If you changed how many paperclips were added: “number of paperclips” (independent) and “number of links needed to break” (dependent).
- If you varied how many seeds were planted per pot: “number of seeds” (independent) and “number of seedlings that germinated” (dependent).
- If you changed the number of coils in a wire: “number of coils” (independent) and “number of volts/current produced” (dependent).
- If you changed the number of dye drops in water: “number of drops” (independent) and “number of seconds to change color” or “number of colored molecules detected” (dependent).

Tell me what you changed and what you measured, and I’ll fill in the exact wording for you.
