  1. No Starter Please get a ruler and a piece of graph paper from the front 

  2. The Graphing World Part of your concrete details!!

  3. Cover Page ALWAYS FIRST in the brads • Unit Number ____________ • Unit Name ____________ • Big Idea (find on the bulletin board) • Real World Connection (Please think of WHY you learned this) • 2 sentence minimum • Ex: Careers these concepts would be useful • Ex: How can you use these concepts outside of the science classroom?

  4. Definition A coordinate graph shows the relationship between two variables.

  5. X-Axis X-axis The x-axis in a coordinate graph is the horizontal line. This is the independent variable. This means that the x-axis information does not rely on the y-axis information.

  6. Y-Axis Y-axis The y-axis in a coordinate graph is the vertical line. It is the dependant variable. This means that the y-axis information relies on the x-axis information.

  7. Equal Intervals This interval is equal to the one above it. Each Interval needs to be equal in order for you to plot. That is because if you have one that is one inch apart and one that is one centimeter apart it will look odd and it will be inaccurate. That’s what graph paper is for.

  8. Labeling # of jumping jacks Time (sec) Each axis needs a label in order for you to know what you are graphing.

  9. Titling Title: Jumping Jack Experiment Each graph needs a title to know what your graph is about.

  10. How to plot data Plotted Point When you start plotting, find the first number on the x-axis. Then find the second number on the y-axis. Where they meet is where you put a point. You have now plotted. It’s important to always plot on graph paper.

  11. Graph Example Jumping Jacks Experiment # of J.J. Time(sec)

  12. Step 1-Read Coordinates (example (5, 3)) • Step 2-The first number should go on the X-axis, for example number 5 is your x-coordinate so you would move to your right 5 spaces. • Step 3-The second number should go on the Y-axis, for example number 3 is your y-coordinate so you would move up 3 spaces. • Step 4-After that, don’t forget where your points are. Once you have done step 2 and 3 you will follow the line your numbers are on and plot a point where they meet. How To Plot

  13. Labeling To fully complete a coordinate graph, you need to make sure you have labeled everything. This means a title, the x- and y-axis labels and units, data, and a summary (statement about what the graph is showing) Title: The Number of Books People Read in a Year Summary: This graph shows the number of books people read increase through the years. 3 2 Y-axis: Number of books 1 0 1 2 3 4 X-axis: Number of years

  14. Remember To Check For: • T Title • L Labels • U Units • D Data • S Summary

  15. In the bar graph above Apples are shown as 10, Pears are shown as 12, and Kiwi are shown as 3.

  16. How many A’s? How many F’s? How many I’s?

  17. How many Bob’s? How many Allie’s? How many Ann’s?

  18. Now it’s your turn to graph. • Graph the data shown in the table (Interpreting Graphics section) for #9 on p.19 in your textbook. • Use a ruler and pencil to neatly create your graph. • Remember TLUDS. • Answer the question in #9 and use that as the summary of your graph.
