Question

Kesha is in charge of dying boiled eggs with her cousins, C.J and Carvin. She read on the directions that you add 2 tablespoons of vinegar to the jar, then add dye tablet, and stir carefully. She decided to add 2 tablespoons of vinegar to one jar, 4 tablespoons of vinegar to the second jar, and 1 tablespoon of vinegar to the third jar.
1. What is the independent variable?
2. What is the dependant variable?
3. What is the Controlled/Constant Variable?

Answer 1

Answer:

Independent: The amount of vinegar

Dependent: The dye result on the egg

Controlled: The type of eggs, the size of jars, the dye tablet, how much she stirs, etc.

Explanation:

The independent variable is what is being changed, which in this case, is the amount of vinegar being added to each jar. The dependent variable is what is being measured or observed. Kesha is looking for what happens to the egg when she adds more vinegar with the dye. Lastly, there could be a couple of controlled variables. Like, the dye tablet, the size and brand of the eggs, the types of jars, how long she stirs each egg, and so on. The controlled are just variables kept constant so that any result observed is because of one singular change, the independent variable.
