Question

scenario 2: the acidity of different types of pop was investigated by putting identical nails into separate glasses containing the different types of pop and one nail into a glass containing water. the nails were removed at regular intervals and the amount of corrosion was observed and recorded before placing the nails back in each glass. iv: dv: cons:

Explanation:

In an experiment, the independent variable (IV) is what is changed, the dependent variable (DV) is what is measured as a result of the change, and the constants (Cons) are what are kept the same. Here, the type of pop is changed, the amount of corrosion is measured, and the nails (identical) and time - intervals of checking are kept the same.

Answer:

IV: Type of pop
DV: Amount of corrosion
Cons: Identical nails, time - intervals of checking
