1
00:00:00,000 --> 00:00:08,680
The NASA Explorer School students from Martinsville Middle School in Martinsville, Virginia, will

2
00:00:08,680 --> 00:00:11,240
preview this program's hands-on activity.

3
00:00:11,240 --> 00:00:12,240
Hi.

4
00:00:12,240 --> 00:00:18,840
NASA Connect asked us to show you this program's hands-on activity.

5
00:00:18,840 --> 00:00:23,160
In this activity, students will do an inquiry investigation on the relationship between

6
00:00:23,160 --> 00:00:27,720
the height from which a marble on a ramp is released and the distance a milk carton at

7
00:00:27,720 --> 00:00:32,980
the end of the ramp is moved along the floor after the ball collides with the carton.

8
00:00:32,980 --> 00:00:36,800
You can download a copy of the Educator's Guide from the NASA Connect website for directions

9
00:00:36,800 --> 00:00:39,200
and a list of materials.

10
00:00:39,200 --> 00:00:45,400
Before you start the activity, your teacher will ask you to answer and discuss several

11
00:00:45,400 --> 00:00:50,400
critical thinking questions based on the experimental setup.

12
00:00:50,400 --> 00:00:57,200
Set up the ramp by using tape to mark one end 0.7 meters high and place an empty milk

13
00:00:57,200 --> 00:01:01,840
carton at the other end of the ramp so that it will catch the marble after it rolls down

14
00:01:01,840 --> 00:01:02,840
the ramp.

15
00:01:02,840 --> 00:01:07,680
You will roll a marble from five different measured heights.

16
00:01:07,680 --> 00:01:12,600
Line up a meter stick on the floor along the distance that the milk carton will travel

17
00:01:12,600 --> 00:01:16,280
after being hit by the marble.

18
00:01:16,280 --> 00:01:21,760
Starting at the first height marked on the ramp, release the marble down the ramp.

19
00:01:21,760 --> 00:01:27,360
On the data collection chart under Trial 1, record the linear distance that the milk

20
00:01:27,360 --> 00:01:31,400
carton travels after the marble hit it.

21
00:01:31,400 --> 00:01:35,120
You will conduct four more trials.

22
00:01:35,120 --> 00:01:38,040
Record the distance the milk carton travels.

23
00:01:38,040 --> 00:01:44,240
Calculate and record the average distance the milk carton traveled.

24
00:01:44,240 --> 00:01:50,400
Continue the experiment by increasing the height from which you drop the marble by 0.1

25
00:01:50,400 --> 00:01:52,400
meter each time.

26
00:01:52,400 --> 00:01:58,040
Students will analyze their data by calculating the potential energy that the marble has at

27
00:01:58,040 --> 00:02:04,160
each height and the kinetic energy that the marble has at the end of each roll.

28
00:02:04,160 --> 00:02:08,320
Now is your chance to put your algebra skills to the test.

29
00:02:08,320 --> 00:02:16,440
Keep in mind that for this activity, you will need to ignore energy lost because of friction.

30
00:02:16,440 --> 00:02:22,400
Based on the data you collect, you will graphically show the relationship between the height from

31
00:02:22,400 --> 00:02:28,240
which the marble is dropped and the distance the carton is moved.

32
00:02:28,240 --> 00:02:33,080
From the graph, select another designated height and predict how far the milk carton

33
00:02:33,080 --> 00:02:35,800
will move if the marble is released.

34
00:02:35,800 --> 00:02:38,600
Go ahead and test your prediction.

35
00:02:38,600 --> 00:02:39,600
Were you correct?

36
00:02:39,600 --> 00:02:44,000
