Lesson 2/Graphing Summative Review

x axis

horizontal axis; Manipulated Independent variable graphed here

Manipulated variable

also called independent variable; changed one at a time by scientists; graphed on the x axis; comes from a list of controlled variables

Title

Includes both manipulated and responding variables; often stated as a question; at the top of a graph

Responding variable

Graphed on the y axis; also called the dependent variable; measured and recorded as data by scientists

Labels

tell what is being graphed on the x and y axes. Examples-time, distance, temperature

line graph

often used to show changes over time

scale

range of data that has to fit on each axes

Y axis

vertical axis; Dependent Responding variable graphed here

DRY MIX

acronym to help remember where to graph Dependent Responding variable (on the Y axis) and the Manipulated Independent variable (on X axis )

Controlled Variables

not graphed; variables that are kept the same to create a fair test

Type of variable that goes on the X-axis

Manipulated Variable

Type of variable that goes on the Y-axis

Responding Variable

Manipulated variable on the 2.1 graph

Time

Responding variable on the 2.1 graph

Temperature

The heating pattern of soil.

It heats up quickly to a higher temperature

The heating pattern of water.

It heats up slowly.

Units

Found in (parentheses), this specifies what measurement system is being used, such as minutes or degrees Celsius

Interval

The value that you "count" by when numbering each axis. It must be consistent along the entire axis.

Data Table

Used to organize results for interpretation and/or graphing

X-Axis Units for 2.1 Graph

(Minutes)

Y-Axis Units for 2.1 Graph

(Degrees Celsius)

The cooling pattern for soil

Loses its heat (cools) quickly

The cooling pattern of water

Cools slowly (hold its heat longer)

Reasons water heats up slower

Lighter in color (reflects more energy), more mass/density

Reasons soil heats up faster

Darker in color (absorbs more energy), less mass/density

Claim

Single sentence answer to the prompt/question

Evidence

Data/statistics/information (often from class activities) that supports the claim and makes it convincing

Reasoning

Explains why the evidence supports the claim (often ties to a scientific principle)
