3. Water is the solvent of life, meaning that many substances can easily dissolve in it. HYPOTHESIS: Increasing the temperature of a salt water solution will result in a greater amount of
salt being dissolved in the solution,
Independent variable:
Dependent variable:

Only need question #3

Hey there!

In an experiment, we have independent and dependent variables. Without them, there wouldn't be an experiment!

The independent variable is the variable that is being changed. For example, in this experiment, the temperature  of the salt solution is our independent variable is changing (increasing in this case)

The dependent variable is what changes when the independent variable changes. The change of the dependent variable is always caused by the change in the independent variable. In this experiment, the amount of salt dissolved in water is the dependent variable, because it is changing as the independent variable is changing.

Let me know if this helps :)
