1. DATA

2. Science is about making observations and collecting data.
Data is organized in tables.

3. Science is about making observations and collecting data.
Data is organized in tables. Organization is by the independent variable (usually the left column).

4. Science is about making observations and collecting data.
Data is organized in tables. Organization is by the independent variable (usually the left column). Independent is known, dependent is unknown (the reason for the research).

5. Science is about making observations and collecting data.
Data is organized in tables. Organization is by the independent variable (usually the left column). Independent is known, dependent is unknown (the reason for the research). Data is plotted on graphs (independent variable on the X-axis).

6. Science is about making observations and collecting data.
Data is organized in tables. Organization is by the independent variable (usually the left column). Independent is known, dependent is unknown (the reason for the research). Data is plotted on graphs (independent variable on the X-axis). Tables and graphs are analyzed to arrive at conclusions.

7. It is on the X-axis, so it is the
The graph represents data collected by a student about the relationship between the volume and the mass of three different samples (A, B, & C) of a material.
Which variable did the student know BEFORE the experiment began?
(1) The mass (g) of each sample.
(2) The volume (cm3) of each sample.
(3) The dependent variable.
(4) The values on the Y axis.
It is on the X-axis, so it is the
independent variable!

8. G R A P H S
Independent variable on the X axis (horizontal).

9. G R A P H S
Independent variable on the X axis (horizontal). EVERY LINE ON SCALE MUST BE EQUAL!

10. G R A P H S
Independent variable on the X axis (horizontal). EVERY LINE ON SCALE MUST BE EQUAL! Always surround points with a circle (or other…)

11. G R A P H S
Independent variable on the X axis (horizontal). EVERY LINE ON SCALE MUST BE EQUAL! Always surround points with a circle (or other…) Use a pencil and take your time!
