Answer:
Independent Variable: amount of water
Dependent Variables: bounce, viscosity, and stretchiness
Control: Standard Slime
Constants: type of container and stirring rod
Explanation:
First, let's define some of these terms:
- Independent Variable: the variable that is manipulated or changed in the experiment
- Dependent Variable: the variable that is measured based on changes to the Independent Variable
- Control: the standards to which the experimental group is compared
- Constants: variables that remain the same
Here, we see that we are "varying the amount of water each time". This means we're changing its amount, so the independent variable is amount of water.
The scenario also says that we "measure the bounce, viscosity, and stretchiness" of the slime, so the dependent variables are bounce, viscosity, and stretchiness.
We also "mix up one batch of Standard Slime for comparison", so we know Standard Slime is our control.
Finally, we "use the same type of container and stirring rod", so those are the constants.
