Analyze Study a topic closely, break a topic down

into smaller parts.

Bar Graph The pictorial display of a set of data

using bars to indicate the value, amount or size of the dependent variable for each level of the independent variable tested. Usually the taller the bar, the greater the value of the dependent variable.

Beaker Tool used to measure volume

Conclusion A summary of what is learned from an

experiment. The last section of a report of an experiment,

it states the purpose, major findings, hypothesis, and recommendations for further study.

Constant All of the factors or conditions that must

be kept the same in an experiment.

Control Group

The group treated normal to which the experimental group is compared.Factors that are fixed in an experiment.

Data

Recorded information from experiments

Data Table A chart to organize and display the data

collected in an experiment.

Degrees Celsius The SI unit of measurement for

temperature.

⁰C

Dependent Variable

The dependent variable is what you measure or observe to obtain your results.

Is found on the y-axis of a graph and in the left column of a data collection table.

Evidence

Data found using a scientific process.

Experiment A test of a hypothesis. It determines if

purposely changing the independent variable does indeed change the dependent variable.

Experimental Group

The group exposed to all conditions of the experiment. The group being tested.

Experimental Procedure Detailed, step-by-step directions for

conducting a science experiment which allow duplication.

Graduated Cylinder A narrow container used to measure the

volume of liquids

Gram (g) The SI unit of measurement for mass.

g

Hypothesis

A testable explanation for an observation or scientific problem . Written as an IF, THEN statement.

Independent Variable The one factor or condition that is

changed by the experimenter Found on the x-axis of a graph. Is recorded in the left column of a data

table.

Interpret To determine the patterns and trends

from scientific data or information.

Intervals The equal size values represented by

the equal spaces marked along the axis of a graph.

Line Graph A pictorial display of data that can be

drawn when the data for both variables are continuous data. The line in a line graph shows the relationship between the independent and dependent variables.

Liter (L) The SI unit of measurement for volume.

LmL

Mass A measure of the amount of matter in an

object.

g

Mean (Average) One of the measures of central

tendency (average); the sum of numbers in a set of data divided by the number of pieces of data.

Measurable Able to be measured

Meter (m) The SI base unit for length and distance.

m

km

cm

Meter stick The tool used to measure distance or

length.

m

km

cm

Model A pattern, plan, representation, or

description designed to show the structure or workings of an object, system or concept.

Observation The use of the sense to describe the

natural world.

Qualitative Data/Observations Observations involving quality or kind,

recorded characteristic that cannot be expressed in numbers.

Color

Shape

Quantitative Data/Observations Observations that involve a number in

the form of an amount or measurement.

1 2 3 4 5 6 7 8 9 10

Repeated Trials Repeating measurements several times.

The more measurements made the more reliable the results.

SI System of Measurement The International System of Units is the

modern form of the metric system and is generally a system of units of measurement devised around seven base units and the convenience of the number ten. It is the world's most widely used system of measurement, both in everyday commerce and in science.

Spring Scale Tool used to measure force or weight

Stopwatch Tool used to measure time.

Testable Question A question that is answered through a

scientific investigation.

???

Thermometer Tool used to measure temperature.

Triple Beam Balance Tool used to measure mass.

Untestable A question that cannot be answered

through a scientific investigation.

Validity The extent to which a test measures

what it claims to measure.

Variable

Factor that can change in an experiment

Volume The amount of space occupied by an

object

LmL

Weight The force of gravity exerted on an

object’s mass.

x-Axis The line along the bottom of a graph on

which the scale for the independent variable is placed.

y - Axis The vertical line drawn on the left side of

a graph on which the scale for the dependent variable is placed.
