Lab#1 - How is a controlled experiment formed?
Have you ever wondered whether light
or dark clothing would be more comfortable on a hot, sunny day? Scientists conduct scientific experiments to
solve problems like this. They use a
process called the scientific method.
Problem

absorption?
Hypothesis
I hypothesize that… I believe that…. I think that… I predict that…
