All right, guys, it's now time for a cue card review. 00:00:00
What is buoyancy-induced convection? 00:00:06
What is the relationship between density and volume? 00:00:09
What is the trend in the density versus temperature graph? 00:00:12
Okay, did you get all that? Let's go visit Dan Giroux in his web domain. 00:00:15
Hi, and welcome to my domain. 00:00:20
NASA Connect has created a really cool web activity to help you understand apparent weight 00:00:28
and to see how astronauts in outer space feel weightless. 00:00:33
We also have a second activity to help you make an important elevator design decision. 00:00:37
First, be sure you have the Squeak plug-in. 00:00:41
It can be downloaded at www.squeakland.org for easy installation. 00:00:44
Once you have the Squeak plug-in installed, 00:00:49
you can access the activity at the NASA Connect website under Dan's domain. 00:00:51
This activity is designed for use by students, teachers, and parents in the school or home setting. 00:00:56
Now, you're ready to start the activity. 00:01:01
On this site, Norbert and Zahid are waiting in an elevator for you to investigate what happens 00:01:05
when you accelerate the elevator. 00:01:10
If you're the hands-on type and want to try it out on your own first, 00:01:12
read the brief directions along the left side of the screen 00:01:16
and start by trying to make Norbert and Zahid weightless. 00:01:19
Then you should read the book on the right side of the screen 00:01:22
for important definitions, brief interactivities, 00:01:25
explorations you should do, and challenges you should consider. 00:01:28
If you want more directions before you start, 00:01:32
begin by reading the book starting with the first page 00:01:34
and click the little right arrow at the top center to go on. 00:01:38
To help you get a head start, velocity is the distance traveled divided by the time it takes. 00:01:41
If the elevator moves Norbert and Zahid downward, 00:01:46
we will say their velocity is a positive number. 00:01:49
To accelerate is to change the velocity. 00:01:52
If you increase the velocity in the downward direction, 00:01:54
we will say the acceleration is a positive number. 00:01:57
Then, if you increase the velocity in an upward direction, 00:02:00
the acceleration will be a negative number. 00:02:04
Positive and negative numbers are essential to describe motion. 00:02:06
Have fun, and explore! 00:02:09
