Science Variables- Mentos and Soda

In one experiment, we compared the reaction of putting a Mento into 500 mL of Coke and Diet Coke. What was the independent variable in this example?

• The type of soda

• The fizzing and reaction

• The number of Mentos, the amount of soda, the type of bottle

• The type of Mentos

In one experiment, we compared the reaction of putting 3 Mentos into 2 Liter bottle of Mountain Dew and a 2 Liter bottle of Dr. Pepper. What was the independent variable in this example?

• The type of soda

• The fizzing and reaction

• The number of Mentos, the amount of soda, the type of bottle

• The type of Mentos

In one experiment, we compared the reaction of putting one Mento into 500 mL of Coke and one Mento into a 500 mL bottle of Diet Coke. Identify the dependent variable(s) in this example?

• The type of soda

• The fizzing and reaction and how much soda was left in the bottle

• The number of Mentos, the amount of soda, the type of bottle

• The type of Mentos
