Question

Sheila conducts an investigation to see how the amount of salt dissolved in water affects the density of the water. Which statement best describes the correct plan for her procedure?

Answer 1

The answer is the type of salt and the amount of water are controls, and the the amount of salt and the density are variables.

Step-by-step explanation:

Answer 2

A list of statements is not proved, but Sheila is definitely conducting an experiment. An experiment consists of someone coming up with a hypothesis and then testing to see if the hypothesis is true. Likely, she will take cups of water with varying levels of salt. Then, she will float the same object in the water, and measure its buoyancy to determine the density.
