Science Fair Question?

Question

im recording temps of rooms and seeing if thermostats correctly record 4 my science fair project.

using bodyheat, fire, and lamp light. How do i keep the fire variable under control so that it dosent affect other room temperatures?!?!?

Answer 1

place a small water fountain between all three (about $5 at a discount store) this will provide a cooling wall between them and keep your readings more accurate. Good Luck!
