Mario studied how far room temperature water would spurt out of a plastic milk carton when 3mm holes were punched at different heights from the bottom of the container. Identify the DEPENDENT variable
-3mm holes
-Distant water traveled out of carton
-Different heights of the holes in the container

The following statement is a hypothesis formed about marsh grass: 
If the amount of nitrogen marsh grass receives is increased, then the height of the grass will increase, because nitrogen is an essential nutrient needed for marsh grass to grow.
What is the independent variable of the statement above? 

• Height of grass
• Amount of nitrogen
• Essential nutrient
• Amount of growth
