Hi, I'm Bianca Baker. 00:00:00
And I'm Kayleigh. 00:00:02
Hello, good morning. I'm Jared, a fifth grader here at King's Cross Education Action Zone. 00:00:03
How's the video conference going? 00:00:09
Hi Bianca and Kayleigh, I'm Kirsty. The video conference is very interesting. 00:00:11
This is our second design meeting and Mr. Logan from NASA Langley Research Centre is helping us with the challenge. 00:00:17
Right now we are reviewing our test results. Why don't you two join us? 00:00:24
Looking at the test data, it looks like we've made some great improvements. 00:00:29
Does anybody have any problems that I can help you with? 00:00:33
Mr. Logan, this is Kirsty. The wheels in our car just seem to spin and the car doesn't go very far. 00:00:36
This is where the redesign process can really help improve your model. 00:00:43
Think about redesigning your car so that the wheels get better traction. 00:00:46
You might try testing different materials for your wheels. 00:00:49
You have to balance the amount of friction you get with the weight you add to your car. 00:00:52
Sounds like it's time for redesign. 00:00:56
Exactly. Let me know what you come up with. 00:00:59
Until next week, be sure to keep track of all your data and your trial notes. 00:01:01
What if we added balloons to the wheels? Would it add too much weight? 00:01:05
I don't think so. Actually, I think rubber bands might just work. 00:01:09
Sounds like a cool project, but what exactly is a mousetrap car? 00:01:13
It is a challenge to build a car using a mousetrap as the only form of propulsion. 00:01:17
Our designs will be judged on the distance the car travels. 00:01:23
How did you begin? 00:01:27
We began by following the design process. 00:01:28
Our teachers gave us a mousetrap car kit, like this one, and some other materials to work with. 00:01:31
We looked over materials and brainstormed ideas. 00:01:37
That's right. We decided we needed to do some research on energy, work, force and simple machines. 00:01:40
Once we felt that our designs was going to work, we started building the model. 00:01:47
But we had a problem when our axles wouldn't turn. 00:01:52
We had trouble with our axles, too. 00:01:55
After more research, we learned that the axle needed sanding. 00:01:57
This helped reduce the amount of friction so that it could spin more easily. 00:02:03
What are you doing now? 00:02:08
We have been testing our cars to see how far they would go. 00:02:09
The first trial didn't go very well. The car only went one meter. 00:02:13
Our second and third trials weren't much better. 00:02:18
We did have a few trials that went over two meters. 00:02:21
After ten trials, we averaged 1.4 meters. 00:02:24
We are hoping that the rubber bands will help. 00:02:28
Testing is really important in the design process. 00:02:31
Yes, it is. By conducting tests, we can see the problem before race day. 00:02:34
Of course. The trials that were over two meters were done at home on carpet. 00:02:40
That's it. The carpet added friction. 00:02:46
In that case, the rubber bands should create enough friction to increase the distance. 00:02:48
Please excuse us, but we have to get to work right away. 00:02:53
Thanks for all the information and good luck in your competition. 00:02:57
Be sure to post your results on the Sci-Files Kids Club website. 00:03:00
We want to know how it turns out. 00:03:04
We will. Bye from London. 00:03:05
Bye. 00:03:07
