  1. Assignments • 1. Grade graphs and conclusions. • 2. Introduction to Reaction Time. • 3. Begin Pre-Lab of Reaction Time.

  2. Reaction Time Lab Assignment #10 • Instructions • 1. Take your hand and create a “C” shape using your thumb and index finger. • 2. Have your partner hold the ruler 1 inch above this hand with the 1 cm end at the bottom and the 30 cm end at the top. • 3. When you are ready, drop the ruler without telling the catcher. • 4. The “catcher” will try to catch the ruler as quickly as possible between their thumb and index finger. DO NOT USE YOUR WHOLE HAND TO CATCH THE RULER. • 5. Look at the number directly on top of the index finger. Record this number as your reaction time.

  3. Data Chart • Construct a data chart for your group. • USE A RULER!!! :) • USE A RULER!!! :) • Make sure each person has 8 trials and an average.

  4. Warm-Up • Think about the Reaction Time Lab from yesterday. • 1. Explain (in sentences) some ways (2-3) we could manipulate this experiment. • 2. Explain what makes a good conclusion.

  5. Learning Target • Use the Official Investigational Design to write a pre-lab, gather data for Reaction Time, and work on the post-lab.

  6. Pre-Lab • Decide on a manipulated variable for this experiment and begin your pre-lab. • USE YOUR YELLOW SHEET TO HELP YOU! • Order is Important! • Question • Hypothesis • Variables • Materials • Procedure with Investigational Set-Up (Labeled Diagram)!

  7. Gather your Research • Make sure to construct a neat table for your data! • USE A RULER! :) • USE A RULER! :) • Once done collecting data, begin writing the rest of the lab. • This is a rough draft. We will type the final drafts.

  8. Try to finish all this in class… • Pre-Lab • Question • Hypothesis • Variables • Materials • Procedure with a Labeled Diagram! • Data Table • Graph • Results • Conclusions

  9. Homework • Finish any parts to the lab you did not finish during class.

  10. Warm-Up • Explain five ways to make sure you get a good grade on your Official Investigational Design science lab.

  11. Learning Targets • Be able to use excel to complete a data table and graph. • Begin typing the rest of the Reaction Time Lab.

  12. Tips for the Computer • 1. Save EARLY! Save OFTEN! • 2. Be patient. Let the computer complete a task before asking for more. • 3. Technical difficulties are part of this project. If you run into a problem fix it and move on. This is not an excuse. • 4. BOLD or underline each section title of the lab.

  13. What you need to complete: • Title • Question • Hypothesis • Variables • Materials • Procedure • Investigational Set-Up (Labeled Diagram) • We will complete the Data Table and Graph together using Excel. • Results • Conclusions

  14. Excel Instructions #1 • Making a data table in Excel: • 1. Open up a new page in Excel. • 2. Create a data table like the one on your lab format sheet. • 3. Enter your trial data in the correct places. • 4. Do not include units in the boxes.

  15. Excel Instructions #2 • Finding an Average: • 1. Highlight your entire table of data. • 2. Find the funny looking “E” in the tool bar at the top. Click on this and a menu will pop down including the word “Average.” Click on this and your average will be calculated for you.

  16. Excel Instructions #3 • Adding borders to your table: • 1. Find the cells icon on the “Home” page of Excel. • 2. Choose format from the pop down menu. • 3. Click on “Format cells” at the bottom of the next menu. • 4. In the format cells choose “Border.” • 5. Click on “Outline” and “Inside” and then click OK. • 6. Your table should now be outlined.

  17. Making a Graph • 1. Highlight your entire table again. • 2. Click on the “Insert” tab at the top of the page. • 3. Find the “Chart” button and choose “Column” and then choose one of the options. • 4. Now you should have a graph. • 5. To label your graph, click on the “Layout” tab and look for “Chart Titles” and “Axis Titles” to complete your labels.
