Susan and Fred performed an experiment to investigate the rates at which various colored cotton T-shirts absorb energy from the Sun.
They used a white shirt, a black shirt, a green shirt, and a red shirt. They placed the shirts outside in direct sunlight. The students used a thermometer to measure the temperatures of each shirt every 15 minutes. The students recorded the data.
Where should the students put a duplicate set of the shirts to use as a control group?
outside and away from direct sunlight
outside and encased in an airtight container
inside a climate-controlled science classroom
in direct sunlight next to the shirts being tested
A student is planning a science fair experiment. Why should the student write a detailed procedure?
It will ensure that the hypothesis will be proven correct.
It will help the student change multiple variables at once.
It will help someone else repeat the experiment and collect similar data.
It will help someone else to change parts of the experiment to test a new hypothesis.
