1. Bell Work 8/23 Please have out your science scenario that you were to have created for class today. If you do NOT have it, you will not get credit for today’s bell work. Also have out the Simpson’s WS that was homework last night.

2. GRAPH NOTES!!

3. Bar Graph A bar graph is best used for comparing data quickly and easily, such as the grade distribution of students enrolled in science class or the growth of plants in different pots.

4. Line Graph A line graph is best used for looking at changes over time, such as the number of bathing suits sold each month during the year or the change in your sister’s height throughout the year.

5. Steps to set-up Bar/Line Graphs First, set up your graphs with an x-axis and a y-axis. The x-axis is horizontal, and the y-axis is vertical. The x-axis represents the independent variable. The y-axis represents the dependent variable. Choose a scale for each of the axes. Select evenly spaced intervals that include all of your data. X-AXIS Y-AXIS

6. Steps cont. Plot your data on the graph. give your graph a title. A title tells the reader what he or she is studying.

7. Pie Chart A pie graph is best used for showing percentages, such as the percentage of the student body who picked certain entrees for lunch or the percentage of your allowance that will go toward purchasing various things.

8. Practice Graph Determine which type of graph should be used to create the graph using the data below. Test-tube #pH 16.7 27.1 37.4 47.1 57.0

9. For each table (a) identify the independent and dependent variable, (b) determine the type of graph to use, and (c) provide a title. Amount of daily sunlight exposure (min) Average height of plants (cm) 5014.8 6014.9 9515.2 7515.1 11016.5 13517.3 10016.1 3011.0

10. Create your own graph Create a data table of information that another person has to create a graph for. This will be your bellwork tomorrow using each others data tables to create their graphs.
