Before R.J. speaks with Dr. Sagnier, I think it's time for you to strengthen your muscles 00:00:00
and increase your muscle stamina. 00:00:08
The students at Oxon Hill Middle School will preview this program's hands-on activity, 00:00:10
entitled Good Stress. 00:00:15
Hi. 00:00:17
NASA Connect asked us to show you this program's hands-on activity. 00:00:18
In this activity, you will be exploring the effects of stress on the muscles in your hands. 00:00:22
And you will gain experience collecting, analyzing, and visually representing data. 00:00:28
You can download a copy of the Educator's Guide from the NASA Connect website. 00:00:35
Before you begin the activity, it's a good idea to review how to make and interpret three 00:00:39
types of plots. 00:00:45
Scatter plots, box and whisker plots, and stem and leaf plots. 00:00:47
Do you remember what a scatter plot is? 00:00:53
A scatter plot is a graph that displays two variables as ordered pairs. 00:00:57
You can use a scatter plot to determine how one variable relates to another. 00:01:02
A box and whisker plot is a graph that summarizes a data set along a number line. 00:01:07
There is a box in the middle and whiskers at either side. 00:01:14
The least value of the data set determines the left whisker. 00:01:19
The greatest value of the data set determines the right whisker. 00:01:24
You form the box using quartiles. 00:01:29
Quartiles divide the data into four equal parts. 00:01:33
Box and whisker plots are useful with very large data sets or for making comparisons 00:01:37
between data sets. 00:01:42
A stem and leaf plot is a graph that uses the digits of each number to show the shape 00:01:44
of the data. 00:01:50
Each data value is broken into a stem, digit or digits on the left, and a leaf, digit or 00:01:51
digits on the right. 00:02:00
A key is needed to explain what your stems and leaves represent. 00:02:02
A stem and leaf plot can quickly show the distribution of a data set and retains each 00:02:07
data value. 00:02:13
Your teacher can show you example problems using different plots. 00:02:14
Now, are you ready to put your math skills to the test? 00:02:18
Good. 00:02:21
Now back to the activity. 00:02:22
Working in groups of two, predict the number of times you will be able to click a clothes 00:02:23
pin between your thumb and index finger in your non-dominant hand for a one minute period. 00:02:29
Record your prediction. 00:02:36
Hold the clothes pin in your non-dominant hand between your thumb and index finger. 00:02:39
While your partner is watching the timer, count the number of times you are able to 00:02:44
click the clothes pin in a one minute period. 00:02:48
Record the result. 00:02:51
Rest for one minute, then predict again and repeat clicking the clothes pin in a one minute 00:02:53
period. 00:02:59
You need to complete three trials. 00:03:00
Be sure to hold the clothes pin the same way during every time trial. 00:03:03
Now, switch roles with your partner and have him or her conduct the exact same experiment 00:03:07
and record the results. 00:03:13
Each group will need to repeat the experiment every other day for two weeks. 00:03:16
Record your predictions and results. 00:03:22
This is the conditioning period. 00:03:24
The stress induced by the clothes pin on the muscles of the hand will cause the muscles 00:03:26
to become stronger and gain stamina. 00:03:32
Make sure you record all your data in a clear and organized way. 00:03:35
This will help you to answer all the discussion questions and to produce visual representations 00:03:40
of the data. 00:03:45
And don't forget to check out the web activity for this program. 00:03:46
It can be downloaded from the NASA Connect website. 00:03:49
