Mark wanted to find out if salt water evaporates faster than pure, fresh water.  He formulated a hypothesis and then placed 100 mL of fresh water in a beaker.  He placed 100 mL of salt water in another beaker.  He placed both beakers on the same hot plate. Mark then watched the beakers and timed how long it took the water to evaporate.  He then analyzed or studied and recorded the results. Which type of scientific investigation did Mark use?

• Comparative Investigation

• Observational Investigation

• Experimental Investigation

• Hypothesis Investigation
