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