3. Important Dates to Write in your Agenda
Tuesday, 1/9: Midterm Retake *tomorrow*
Tuesday, 1/16: Submit Data Table, Graph, Results & Conclusion *multiple extra days!*
Thursday, 1/25: School Science Fair *1 extra day!*

4. Homework for Tonight: Study for the Midterm Retake
Any questions for me?
Work on your Science Fair Graph

5. Science Fair Graph Take your Science Notebooks out
Lesson Objective: Students will be able to identify the type of graph they need to use for their Science Fair project.
Students will be able to draw a bar graph

6. Science Fair Graph
All information that you collect and write about in your results section will also be represented in a graph. Your results, graphs and data tables will include the same information throughout, but the information will be displayed in different ways. When choosing a graph, be sure to use the most appropriate one.

7. Bar Graphs
Bar Graphs are the most common type of graph. They should be used to display data that shows a cause and effect relationship. A bar graph should include:
Numbers (scale) in even intervals (1’s, 2’s, 5’s, 10’s, 100’s, etc.)
Labels for the horizontal and vertical axes.
A title that reflects the information that is being graphed.

8. Line Graphs
Line graphs should be used to display continuous data. For example, showing changes in the dependent variable over time or distance. On a line graph, the horizontal (x) axis is always the independent variable and the vertical (y) axis is always the dependent variable. It should also have:
Numbers (scale) in even intervals (1’s, 2’s, 5’s, 10’s, 100’s, etc.)
Labels for the horizontal and vertical axes.
A title that reflects the information that is being graphed

9. Pie Graphs
Pie Graphs should be used only when the results are best shown as a percentage of a whole. They do not show changes over time. The data of a pie graph should include:
A circle that is divided into the necessary number of parts.
Sections (or slices) of the pie should be sized accurately according to the data.
Each section of the pie should be labeled or color-coded with a key.
A title that reflects the information being graphed.

10. Turn & Talk
Partner A: describe your Science Fair Experiment to your Partner B.
Partner B: suggest the type of graph that Partner A should use based on their experiment. Feel free to ask any questions for more details if needed.
Partner A: write down the type of graph you should use for your Science Fair experiment

11. There are two suggested ways you can create a graph:
Be extra careful when using a computer to create your graphs. The computer will create any type of graph you want, whether it is the correct graph to display your type of data or not. Also, many computer graphs leave off important titles and labels. You may use any on-line or computer graph program, such as Microsoft Word.

12. Instructions for creating a graph
1. Collect your data in one place (data table)
2. Label your graph and your axes. When presented with your graph, other people should be able to figure out what is plotted without asking you.
a. The independent variable will go on the x-axis (the one parallel to the bottom of the page), and the dependent variable will go on the y-axis (parallel to the left hand side of the page).
b. Titles of graphs are usually "Y versus X"
3. Determine the range of your data. In order to determine how big a graph to make, we need to determine how much the numbers vary.
4. Write the numbers on the graph. The numbers should be evenly and logically spaced. The axis should be marked off in increments like (1,2,3,4,5,6) or (2,4,6,8), NOT (1.3, 2.6, 4.8,..) or anything else weird.
5. Labels on the axes must have units. (such as centimeters, seconds)
6. Plot your data

13. Practice: Create a Graph
Follow the instructions on the back of your handout and use the example data table below to practice creating bar graph.

Ball Temperature
Trial 1
Trial 2
Trial 3
Average
Room Temperature 43 44 41
42.67
Hot 25 24 20 23
Cold 21 18 15

14. Your graph should look similar to this:
