NASA Connect segment involving students in an activity that investigates the cycles of solar flares. The video incorporates problem solving strategies while students compute percentages of M-class flares and graph data.
Thanks, Michelle. Say, how would you like to plot out the cycles of solar flares? Students
00:00:00
at Hardy Middle School in Washington, D.C. will show you how. Check out my nose.
00:00:09
Hi, we're from Hardy Middle School. Here in Georgetown, Washington, D.C.
00:00:14
NASA Connect has asked us to show you this hands-on activity.
00:00:21
It's called X-Ray Candles. Solar flares on your birthday. Here are the main objectives.
00:00:25
You'll discover the solar cycle through an investigation of solar X-ray flares. You'll
00:00:31
record the total number of flares in your birth month over an 11-year period. You'll
00:00:36
compute the percentage of M-class flares that occur. You'll graph your findings to help
00:00:41
you identify the long-term pattern of flare activity on the sun. And you'll incorporate
00:00:45
problem-solving strategies in a real-life application. The list of materials you'll
00:00:50
need for this activity can be downloaded from the NASA Connect website. The class
00:00:54
will be divided into groups according to their birth month. Teachers will provide each group
00:00:59
with solar flare data for the corresponding birth month, and each student with a calculator,
00:01:03
graph paper, and student data charts.
00:01:08
Good morning, class. Today, your job is to plot and analyze solar flare data from a satellite
00:01:10
and determine the solar cycle of the sun.
00:01:17
First, add the total number of flares that occurred in your birth month for each year.
00:01:21
Record that number in the last column of each row of the solar flare datasheet.
00:01:25
Second, add all the numbers in the last column of the solar flare datasheets to determine
00:01:30
the total number of flares in your birth month for each year.
00:01:34
Record that number for each year in the box at the bottom of each page of the solar flare
00:01:38
datasheet.
00:01:43
Next, add the total number of M-class flares in your birth month for each year.
00:01:43
Record the total number of M-class flares for each year in the box at the bottom middle
00:01:48
of each page of the solar flare datasheet.
00:01:52
What did you get for your birth month?
00:01:55
Fourteen.
00:01:58
Groups will need to collaborate with each other to get information on the total number
00:01:59
of flares and M-class flares for all months in each year.
00:02:03
Record the data on the student data chart.
00:02:06
Record the total number of flares and M-class flares for each year on the student chart.
00:02:09
In this data, compute the percentage of M-class flares for each year by using the equation
00:02:14
M-class flares divided by total number of flares multiplied by 100.
00:02:19
Students will then plot the percentage of M-class flares versus year.
00:02:25
Okay, why is it important for researchers and scientists to know when solar maximums
00:02:30
and solar minimums will occur?
00:02:36
Connor.
00:02:38
So they know when solar storms will hit the earth.
00:02:40
Anybody else?
00:02:43
Allison.
00:02:44
So they can warn us if the electricity will go out in our homes.
00:02:45
Special thanks to the AIAA National Capital Section and the AIAA mentors from the University
00:02:49
of Maryland who helped us with this show.
00:02:55
Thank you.
00:02:59
We had a great experience.
00:03:00
And we encourage teachers to visit our website to learn more about the AIAA mentorship program
00:03:01
in your area.
