Assignments

1. Grade graphs and conclusions.

2. Introduction to Reaction Time.

3. Begin Pre-Lab of Reaction Time.

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.

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.

Learning Target

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

Pre-Lab

Decide on a manipulated variable for this experiment and begin your pre-lab.

(Labeled Diagram)!

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.

Homework

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

Warm-Up

Explain five ways to make sure you get a good grade on your Official Investigational Design science lab.

Learning Targets

Be able to use excel to complete a data table and graph.

Begin typing the rest of the Reaction Time Lab.

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.

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

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.

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.

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.

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.
