For the following experiment, write a possible hypothesis, and then identify the independent variable, dependent variable, and controlled variables. Susan wants to find the fastest route to drive to youth group. She can take the freeway, arterials, or residential roads on her way to youth group.

We discussed the importance of having only one independent variable, but trying to test more than one independent variable is an error many people make. In the following experiment, identify the errors that the experimenter made and summarize a valid way to test his research question: What cooking spray best keeps food from sticking to a pan? In the morning, Dan uses grapeseed oil to cook eggs for breakfast; for lunch, he uses vegetable oil spray to coat a muffin tray and cooks cornbread to eat with his chili; for dinner, he uses olive oil to pan cook a hamburger patty.

Design a simple experiment that you could conduct at home. What is your hypothesis? What are the independent, dependent, and…

1st question:
possible hypothesis: What is the fastest route to drive through to reach the youth group?
Independent variable: This would be the speed of the car she will be driving.
Dependent variable: The length of time it would take Susan to arrive in her destination using each route.
Controlled variable: The speed of the car she will be driving. This should remain constant in every route she takes.

2nd question:
What cooking spray best keeps food from sticking to a pan?

Dan used different independent variables and dependent variables. There is nothing to compare in each experiment because there is no controlled variable.

breakfast: grape seed oil in a pan to cook eggs.
lunch: vegetable oil spray in a muffin tray to cook cornbread
dinner: olive oil in a pan to cook a hamburger patty.

The cooking oil used are not all in spray form. The pan is only used in two occasions. Different type of food were cooked.

Dan should used cooking oils in spray form. He should also use only one pan and only one type of food to determine whether said food will stick to the pan using a certain cooking oil spray.
