Vocab Unit 1 Part1

an instrument used to measure changes in atmospheric pressure

• Barometer

• chromotography

• buret

• fume hood

a flat bottomed, cylindrical container made of glass or plastic that is used to hold, pour, or heat (glass)

• beaker

• crucible with lid

• erlenmeyer flask

• evaporating dish

A way of separating and identifying mixtures of solutes in a solution; the method depends on the affinity of the different solutes in the mixture for the medium through which the solution moves

• chromatography

• graduated cylinder

• dependent variable

• buret

an insulated wire formed into a triangle to support a crucible during heating substances to high temperatures

• clay triangle

• buret

• beaker

• crucible with lid

a container made of metal or a refractory material used for heating substances to high temperatures

• crucible with lid

• evaporating dish

• beaker

• fume hood

the factor in a controlled experiment that is not changed

• dependent variable

• independent variable

• hypothesis

• model

a series of steps that guides engineering teams as they solve problems; it emphasizes open-ended problem solving and encourages one to learn from failure; steps include researching the problem , developing possible solutions, and constructing a prototype to be tested

• engineering design process

• dependent variable

• buret

• model

glassware with a flat bottom, conical body, and a cylindrical neck typically used in titrations

• erlenmeyer flask

• buret

• beaker

• crucible with lid

a small glass dish that is used to evaporate a substance; it is also used as a cover for a beaker

• evaporating dish

• crucible with lid

• Erlenmeyer Flask

• beaker

a cleansing solution or a station connected to water line that is used to rinse your eyes after exposure to chemicals or other irritants

• eye wash/eye bath

• fume hood

• chromatography

• buret
