Fred is testing what type of sneeze spreads the most bacteria. He will put a visible liquid in his mouth to see how it spreads and then sneeze. He will then compare how much bacteria was spread. What is the IV?

The type of sneeze

Experiment 3

Mike is testing if when you add more water to a water-salt mixture, the longer time it will take for the salt to crystallize. He will have a control 1 liter of water and 5 teaspoons of salt. He will also have a test of 1 1/2 liters of water and 5 teaspoons of salt. He will check every day and record the results. What is the IV?
