Fair Test

  1. 1. Fair Test Cyrus Eludo
  2. 2. What is a Fair test?
  3. 3. “(…)You conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same.” -ScienceBuddies.org
  4. 4. Which one is faster going down a slope? • Car 1 (Green) • Good condition car body • (tires, engine, etc.) • Negligible friction on the ramp • Gently released from the starting line • Car 2 (Red) • Good condition car body (tires, engine, etc.) • Negligible friction on the ramp • Slightly pushed for a jump start Is that a fair test? NO!
  5. 5. We put seeds of the same kind in three pots with fertilizer and rich soil
  6. 6. But, we run out of soil so we put the seeds without fertilizer in three pots filled with sand.
  7. 7. We put all six pots in the same location and water each one with the same amount of water every other day
  8. 8. Now that’s fair! Thank you!
