Across
  1. 3. used to protect/shield eyes
  2. 4. used to hold + observe small objects
  3. 6. variables with labales; categorial
  4. 10. used to measure temperature
  5. 13. little spread over data
  6. 14. error caused by inaccurate equipment or problems with method or observation technique; fixed by changing method
  7. 18. something other than IV that can affect outcome; fixed by keeping it the same
  8. 19. IV changed and everything else the same
  9. 20. near true value
  10. 21. repeatability and reproducibility
  11. 23. result different from expected
  12. 25. used to measure volume
Down
  1. 1. uses gas to produce heating
  2. 2. variable you measure
  3. 5. error caused by uncontrollable factors; reduced by repeating and averaging
  4. 7. variable you change
  5. 8. used for heating and holding liquid chemicals
  6. 9. redo method, similar results
  7. 11. used to pour + measure liquids
  8. 12. used to hold test tubes when hot
  9. 15. variables with numerical value
  10. 16. others do method, similar results
  11. 17. how tiny a measurement is
  12. 22. needs conclusion + fair test
  13. 24. used to pour liquids into small opening
