Thanks, Sten. 00:00:00
We'll get back to you a little later in the program. 00:00:03
But first, students from Brewster Middle School 00:00:06
at Camp Lejeune, North Carolina, 00:00:08
will preview this program's hands-on activity. 00:00:10
Hi, NASA Connect has asked us 00:00:14
to show you this program's hands-on activity. 00:00:17
In this activity, you will use graphing, measurement, 00:00:20
and ratios to construct a scaled model of the solar system 00:00:23
and relate each planet to the sun. 00:00:27
And you will explore the scales needed 00:00:30
to represent the size of the planets 00:00:33
and the distances to the sun. 00:00:35
You can download a copy of the educator guide containing 00:00:38
directions and a materials list from the NASA Connect website. 00:00:40
Working in groups, students will complete the activity 00:00:44
by using the scale model chart and the planet templates. 00:00:47
Each group will be assigned a planet. 00:00:52
Cut out your assigned planet using the planet template. 00:00:54
The scale for this activity is one toilet paper 00:00:58
sheet equals 30,102,900 kilometers. 00:01:01
Using the scale, students complete column four 00:01:06
on the scale model chart. 00:01:09
Remember the math concepts you learned earlier in the program? 00:01:11
This is your chance to put your math skills to the test. 00:01:14
Next, you will complete column five on the scale model chart. 00:01:17
The scale needed to complete this column 00:01:21
is one AU, or astronomical unit, equals five toilet paper 00:01:23
sheets. 00:01:28
Groups should check each other's work 00:01:29
to make sure all values are correct. 00:01:31
After completing the scale model chart, 00:01:33
each group should roll out the number of toilet paper 00:01:36
sheets needed for its assigned planet. 00:01:38
Now it's time to head to the staging area. 00:01:41
This could be in a gym, hallway, or even outside. 00:01:43
Place the sun in a central position. 00:01:47
Students, attach your pre-measured toilet paper strip 00:01:50
to the sun and let it extend outward in various directions. 00:01:53
Don't forget to tape your assigned planet 00:01:57
on the end of the strip. 00:01:59
You will need about 23 meters, or 75 feet, in one direction. 00:02:01
Based on your solar system model, 00:02:06
you will be asked to answer several critical thinking 00:02:08
questions. 00:02:10
Graphing is a great way to visually represent data. 00:02:11
Each group will construct and analyze 00:02:15
two graphs using an appropriate type of graph 00:02:17
and scale of your choice. 00:02:21
Be careful with the type of graph you choose. 00:02:22
Don't forget to check out the web activity for this program. 00:02:25
You can download it from the NASA Connect website. 00:02:28
Great job, Brewster Middle School. 00:02:34
OK, now that you guys have a preview of this program's 00:02:37
hands-on activity, now it's time to pause the program 00:02:39
and see if you can construct a scale model of the solar 00:02:43
system. 00:02:46
