graduated cylinder
used for precise measurement
what are graduated cylinders made out of
polyporpylene or polymethylpentene
are flasks and beakers more accurate than graduated cylinders
no graduated cylinders are more accurate
what does polypropylene help with
shatter resistant, resistant to chemicals, CANNOT be heated
polymethylpentene
known for clarity
where should measurements be made on a graduated cylinder
at eye level
erlenmeyer flask//beaker
used to mix, transport and react// CANNOT be used for MEASUREMENT
pipette
used to accurately measure small amounts of liquid
balance
measures mass and force
electronic balance
most accurate for measuring mass and force
plate
where the item to be weighed is placed
what are beams
little weights
hypotheses
educated guess, provide starting point for experiment
assumptions
taken to be fact without proof for the purpose of performing a given experiment
scientific model
mathematical statement to describe a physical behavior
scientific law
produce accurate and repeatable results
theory
more recently developed, it can be disproven
