|Science; Earth and Space Systems
- formulate questions about and identify needs and problems related to objects and events in the environment, and explore possible answers and solutions
- plan investigations for some of these answers and solutions, identifying variables that need to be held constant to ensure a fair test and identifying criteria for assessing solutions
- compile data gathered through investigation in order to record and present results, using tally charts, tables, labelled graphs and scatter plots
- communicate the procedures and results of investigations for specific purposes and to specific audiences, using media works, written notes and descriptions, charts, graphs, drawings, and oral presentations
Math; Data Management and Probability
- construct line graphs, bar graphs, and scatter plots both by hand and by using computer applications
- make inferences and convincing arguments based on the analysis of tables, charts, and graphs

Do you think there is a relationship between the diameter of a planet and the
Let's find out.
What is your hypothesis?
Do you think if the diameter of a planet is larger, then the mass will also be greater? _______
Gather the Data
Use the data found at;
to complete the following table.
|Planet||Diameter (km)||Mass (Earth=1)|
Graph the Data
1. Open a new AppleWorks word processing document.
2. From the Format menu, select Document. Change all margins to .5 in.
3. From the Window menu, select Show Tools.
4. Click on the Spreadsheet tool .
5. Move the mouse to the document and draw the outline for the spreadsheet (data table). Your table needs 3 columns and 10 rows. (You can resize the spreadsheet by clicking and dragging the handles after you have created it.)
6. To enter information into the cells, click on the cell, type the information and then press the Enter key.
7. Set up your table as follows and then enter the data.
To make the graph;
8. Highlight the data in columns B and C (click and drag from B1 to C10).
9. From the Options menu, select Make Chart.
10. Click on X-Y Scatter, then click on the Labels button.
11. In the Title box, type an appropriate title for the graph and then click in the box beside Legend to clear the check mark. Click OK.
12. Drag the graph to the edge of the page and then click and drag the
handles to resize the graph so it fills the available space.
Interpret the Graph (Conclusion)
What relationship between planet diameter and mass does the graph show? ___________________
Use a similar procedure to investigate one or more of these relationships;
mass of a planet and gravity
diameter and length of day
distance from Sun and time to orbit Sun
diameter and density
diameter and number of moons
