Question

Hi, guys so I'm doing an experiment and need help finding out the types of variables. In my experiment, I am using a narrow straw, a wide straw, and some colored water to find out how different variables affect capillary action. I'm trying to find out what is the controlled variable, independent variable, and dependent variable.

Answer 1

The controlled variable is straws. Independent it the water and dependent is the capillary action.

Step-by-step explanation:

The Independent variable is the water because its not chaninging thorughout the experiment and has no conqueunces on the other varibales. The controlled is the straws because you are controlling the different diameters in which the straws are (narrow/wide). Then as you change your controlled variable your dependent varible will change- which is the affect on capillary action.

Hope this helps.

Answer 2

Controlled variable=coloured water

Dependant variable=amount of water

Independant variable=narrow and wide straw

Have a nice day
