Thanks, Dr. Stevens. 00:00:00

I really had no idea how much the clouds impacted our weather. 00:00:04

Well, now it's time to see how much you've learned, and it's time for you to size up 00:00:07

the clouds. 00:00:11

Students from the School of International Studies at Meadowbrook in Norfolk, Virginia, 00:00:13

will preview part one of this program's hands-on activity. 00:00:17

NASA Connect asked us to show you this program's hands-on activity. 00:00:22

In this activity, you will set up three simulated clouds representing three different cloud 00:00:27

types. 00:00:32

You will use different methods to estimate precipitation content in each cloud type. 00:00:33

The precipitation from each cloud will be released, and you will compare your estimates 00:00:39

with what is actually occurring on the ground. 00:00:44

In addition to learning about weather forecasting, we will also be using math skills like estimation, 00:00:48

percentages, averages, and ratios. 00:00:53

You can download a copy of the Educator Guide containing directions and a list of materials 00:00:56

from the NASA Connect website. 00:01:01

Teachers should cut a three-quarter inch diameter hole in the center of the bottom of three 00:01:03

different foam cups. 00:01:09

Cover the hole with a Post-it note. 00:01:11

Place about one ounce of M&Ms in a plastic bag. 00:01:13

Twist the bag tightly and tie the excess bag in a knot. 00:01:17

Cut off the excess to make a compact bundle. 00:01:21

Make a second bag following the same procedure. 00:01:24

Select any cup. 00:01:27

Pour in about half full of M&Ms. 00:01:28

Then add a bundle of M&Ms and fill more loose M&Ms into the cup until it is three-quarters 00:01:31

full. 00:01:38

The loose M&Ms will represent the amount of precipitation in each cloud. 00:01:39

Fill the second cup to about one-third full of M&Ms. 00:01:44

Fill the third cup to about one-fourth full of M&Ms. 00:01:48

Add a bundle of M&Ms and then continue filling with loose M&Ms until the cup is one-half 00:01:52

full. 00:01:58

Secure the lids on the cups by taping the joint with masking tape or transparent tape. 00:01:59

Invert the cups and label each cup cloud type X, Y, and Z. 00:02:05

Below this, write the actual capacity of the cups chosen. 00:02:10

Line up the cups on a table. 00:02:15

Students will estimate how many ounces of precipitation each cloud type contains. 00:02:16

Write the estimate onto the data sheet. 00:02:22

Next, remove the post-it note and shine a flashlight into the hole. 00:02:25

Make a new estimate of how many ounces of precipitation each cloud type contains and 00:02:29

record it on your data sheet. 00:02:35

Do this for each cloud type. 00:02:37

Choose a person to weigh each cloud type cup on a scale. 00:02:39

Record the weight ounces. 00:02:44

Remember, weight ounces do not equal volume ounces. 00:02:46

Once you have collected all of the data, you will revise your precipitation estimate. 00:02:50

Based on your data, answer these questions. 00:02:55

How does the data compare with your estimates? 00:02:58

What factors might cause differences? 00:03:01

If you had another cloud type of a different size, would the data collected make for a 00:03:03

more accurate precipitation forecast? 00:03:09

Discuss these findings with your class. 00:03:12
