100

definition of accuracy

how close a measurement is to a known/accepted value

100

Water displacement can be used to measure this

Volume

200

The technique you should use for smelling a chemical in chemistry

wafting

200

Definition of precision

How close measurements are to each other. Repeatability

200

1 g/mL

300

Meaning of this chemical symbol

Biohazard

300

The rule for how many digits to include in a measurement

Enough so that the last digit is an estimate (one digit point beyond the smallest hashmark)

300

Number of sig figs in the number: 2 snails

infinity

300

The type of variable that is plotted on the x-axis

independent

300

An object has a density of 1.25 g/mL. This will happen when it is placed in water

sink

400

The highest number you'd see on an NFPA diamond label

4

400

Name of the curved line formed by liquids in a graduated cylinder

meniscus

6

400

The type of variable that the scientist measures to understand the effect of the experiment

dependent

400

The formula for density

d=m/V

500

500

If a ruler has hashmarks at every 10th of a centimeter, the number of decimal places your measurement (in cm) needs to have

2 (to the hundredths place)

500

The number of liters in a hectoliter

100

500

The difference between a control group and a controlled variable

A control group does not receive the independent variable treatment and is used for comparison to the experimental group. A controlled variable is any variable that is kept the same throughout an experiment
