Chemistry Standard 12c: Identify possible reasons for inconsistent results, such as sources of error or uncontrolled conditions.
When scientists perform an experiment, not everything can go right. There's always something that can go wrong. It could be the experimenter at fault, the equipment, or maybe just some other unevitable natural flaws.
Human Error:
- measuring the wrong amount of substance (beaker, scale)
- reading the wrong result (thermometer, scale)
- scale not zeroed
- incorrect temperature setting
- miscalculations
- wrong instrument use
- not cleaning up in between eqiupment use
Equipment Error:
- broken scale
- unequal spacing (beakers, thermometers)
- holes that let unwanted gases in
Other Errors:
- weather
- no constant
