You know, students in Baton Rouge, Louisiana, are also charged up about today's classroom activity. 00:00:00
Hi! We're from the Strumer Middle Medicine School in Baton Rouge, Louisiana. 00:00:07
NASA Connect asks us to help you understand how to do the student activity for this program. 00:00:12
Earlier, we learned that the NASA ProSense experiment uses long, conducting wires called tethers. 00:00:18
The tethers make electricity that can be used to move satellites. 00:00:24
Now, we're going to simulate the research they do at NASA by constructing and using the Make-It-Go Electrodynamic Demonstration Unit, or EDU for short. 00:00:28
First, let's make the EDU. 00:00:39
The materials you need, magnets, batteries, wire, and very small light bulbs called light-emitting diodes, are inexpensive and easy to find. 00:00:41
Remember, safety is our number one concern at NASA, so be sure to listen carefully and follow the safety guidelines. 00:00:50
Now that the EDU is made, you'll need to make an electrical current level controller for the EDU. 00:00:57
The current controller is made using only regular paper and a set of five resistors. 00:01:03
Be sure that all your wires are connected correctly. 00:01:08
This will create what is called a closed circuit that allows the electricity to flow freely through the EDU. 00:01:11
Now you're ready to observe and predict what happens to the light from the LED when you change the amount of electricity flowing through the circuit of your EDU. 00:01:17
If the wires are not connected properly, an open circuit exists and the flow of electricity through the EDU is broken. 00:01:25
As a class, discuss whether there's a pattern to describe what happens to the brightness of the light when the electricity level increases. 00:01:32
The EDU is a model of the actual propulsion system tested in the process mission. 00:01:40
You'll use the EDU to observe and understand that if a wire has electricity flowing through it, the wire can actually move if it is placed near a magnet. 00:01:46
You'll measure, record, and graph the relationship between the electric current and wire coil movement. 00:01:56
Then, you'll analyze the results just like NASA researchers do. 00:02:03
Next, construct the coil as directed in the lesson guide. 00:02:07
Add the wire coil along with the magnet to the EDU. 00:02:11
Observe what happens to the wire coil's motion when the magnet is present. 00:02:15
Looking at your previous set of test results, what do you think will happen to the wire coil when the current level increases? 00:02:20
Change the current levels and measure and record the distance that the wire coil moves at each level. 00:02:27
Each time you test a new current level, compare the results with your classmates. 00:02:34
Average the test results at each current level. 00:02:39
After you've completed testing, your teacher will get you started on graphing your data, then help you understand how to analyze your results. 00:02:42
Great work, class! But how can we display the data that we've collected on a graph? 00:02:50
Think about the information we're comparing. 00:02:55
Now that we have our graph labeled, one person from each group should come up and graph the average distance the coil moved at each current level. 00:02:58
This looks great! What type of graph is this? 00:03:08
A bar graph? A line graph? A scatter plot? 00:03:11
What was the maximum distance our wire coil moved? 00:03:15
What current level produced the greatest movement? Why do you think this is so? 00:03:19
Class, can you guess which electricity level the circuit is set on based on how far the wire coil is moving? 00:03:23
If I run some more tests, I know that I can find out. 00:03:32
Yeah! Let's make it go again! 00:03:35
