SCIENCE HELP! experiment question .. experiment down?
When Jenny was outside she looked around at the big rocks (rocks small), grass, and concrete of the parking lot paved and asked "What area / material is absorbing more energy from the sun So they went to discover grabbed response:?. Fahrenheit thermometer stopwatch a sheet of paper decided it would be recording temperature each object after allowing to stand 2 minutes in the sun. she was going to record two temperatures for each object (At 2 to 4 minutes). The experiment could take 12 minutes and collected six temperatures. Now my question is: What is the manipulated variable of the experiment and why? NEED MORE ANSWERS PLEASE!
Part of description that includes "and". Jenny is taking the temperature to 2 minutes and 4, this is the only manipulated variable, all others are constant. The sun can go out and change the temperature, but that is not manipulated.
