gram

• a unit used to measure volume

• a unit used to measure mass

• an experiment that is designed to minimize the effects of variables other than the independent variable

• a response to a change (effect)

meter

• a unit used to measure volume

• a unit used to measure length

• a unit used to measure mass

• a response to a change (effect)

dependent variable

• a response to a change (effect)

• a series of steps followed to solve problems

• anything in an experiment that changes in some way

• the scientific study of non-living matter

control

• a measure of the amount of matter in an object

• the ratio of mass to volume

• an experiment that is designed to minimize the effects of variables other than the independent variable

scientific methods

• a series of steps followed to solve problems

• anything in an experiment that changes in some way

• a measure of how hot or cold something is

• a pattern, plan or description designed to show the structure or workings of something

hypothesis

• A summary of many experimental results and observations; tells how things work

• a unit used to measure distance or length

• the explanation that is based on scientific research or observations and can be tested

• Facts, figures, and other evidence gathered through observations.

liter

• a unit used to measure distance or length

• a unit used to measure mass

• a unit used to measure volume

• the amount of matter in an object

independent variable

• The amount of space an object takes up

• A summary of many experimental results and observations; tells how things work

• Information obtained through the senses.

• the scientist changes this (cause)

variable

• anything thast changes in some way or can be changed

• A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.

• well-tested explanation that unifies a broad range of observations

• Information obtained through the senses.

density

• the ratio of mass to volume

• the amount of matter in an object

• a summary of many experiments or observations; tells how things work

• the explanation that ties together many hypothesis and observations
