1. Graphing in Science
XKCD

2. Graphing is important in science because:
allows you to visualize data
allows for comparison of experimental results

3. Line graph Kinds of Graphs in Science…
It is common in science to use two main types of graphs
Line graph
These mostly graph numbers stuff.
They compare two variables. They can show how stuff changes over time.

4. Bar graph Kinds of Graphs in Science…
It is common in science to use two main types of graphs
Bar graph
They make comparisons between different variables very easy to see.

5. 1. Graphs have an X and Y axis
Graphing basics…
1. Graphs have an X and Y axis
The Y axis is the Vertical axis.. Just remember… a Y needs a leg to stand on
The X axis is the horizontal axis Y

6. Parts of a Graph that you MUST have to get full credit…
Title: This must reflect what the X and Y axis are all about. Other people should be able to figure out what is plotted without asking you. Titles of graphs are usually "Y versus X“.
Y Label
Units if needed
X Label
Units if needed

7. DRY MIX Graphing basics
Here’s a trick to remember how to set up a graph… just remember
DRY
MIX

8. The perfect MIX… a DRY but graph-able mix
Graphing basics
The perfect MIX… a DRY but graph-able mix
DRY MIX stands for…
DRY
ependent variable
esponding Item
- axis
MIX
anipulated item
ndependent variable
- axis

9. Lets practice determining independent and dependent variables
Graphing basics
Lets practice determining independent and dependent variables
Number of contaminates- volcanic lake
Amount of lead in the soil- landfill locations
Number of math problems - Homework assignment
IQ points- Shoe size
Planets – solar system

10. Graphing basics… Let’s practice
A student conducts an experiment and collects the following data…
Homework problems assigned Time in hours
10 problems 1
25 problems 2
5 problems 3
35 problems 4
15 problems 5
Let’s PRACTICE!!!!
How would we put this data into graph form?

11. DRY MIX Graphing basics… First… determine the variables:
Homework Problems per Day of the Week
Next… set up your graph
then… plot your data
DRY
Homework Problems
Time (hours)
MIX

12. Graphing basics… Let’s practice
A coach conducted research on the relationship between sprained ankles and the number of hours practicing in sports.
Sprained Ankles Hours practicing
1 5
2 10
3 12
4 20
5 24
How would we put data into graph form?

13. DRY MIX Graphing basics… First… determine the variables:
Number of sprained ankles and hours in practice
Next… set up your graph
then… plot your data
Number of sprained Ankles
DRY
Hours in practice
MIX

14. Make your own graph
