ctivity 1

1. Run the computer animation by typing:


2. Slow the animation by typing:


3. Observe the animation, identify the hurricane.


4. Answer the observation questions.

uestions

1a. Which direction is the hurricane moving? How do you know?

1b. Which direction are the clouds in the hurricane moving?

1c. Using a copy of chart, locate the

shape of the hurricane and identify the strength of the hurricane.

ctivity 2

1. Before beginning the activity, the teacher should
   set-up the computer system and display the picture
   “SCALE” from the Romeo disk by typing:


2. Tape a piece of acetate to the computer monitor.


3. Students need to copy the distance scale from the
   screen onto the acetate.


4. View the individual hurricane sequence by typing:


5. Mark the center of hurricane Romeo.


6. Trace the coastline onto the acetate.


7. Repeat pro c e d u res 4 & 5 for frames Romeo.2, ...Romeo.9.


8. Remove the acetate from the computer screen.


9. Connect the points marking the center of the hurr i c a n e.

ecord the Following Information on Your Data Sheet

2a. Using the scale, determine the distance between each point.

2b. Determine the total distance hurricane Romeo traveled.

2c. Determine the speed the center of the hurricane moved between each dot.

2d. Determine the average speed the hurricane moved.

The activity should employ a

scale of about 1 centimeter

equals 136 km. This pro p o rt i o n

was developed using a CRX

monitor and may be adjusted

for monitors of diff e rent size by

the following method:

Play Romeo 1 to display a still

frame of hurricane. Enhance

image to view pixels. Measure

f rom hurricane center to south-

e rn edge by counting the num-

ber of pixels. Multiply that num-

ber by 8 (there is an 8 km

resolution per pixel for the

image). Restore image to default

size on screen. Using a center of

the hurricane to the southern

edge. The metric distance can

then be placed in ratio to actual

d i s t a n c e. *

Example: On CRX monitor

t h e re were 17 pixels between

center and edge (re m e m b e r

frame is enlarged) 17 x 8 km -

136 km. Standard frame mea-

s u red 1 centimeter from center

to edge, resulting in a 1 cm =

136 km scale.

* The GOES image is distorted

by the curve of the Earth.

That has been ignored for

the purpose of this activity,

but should be considered

for higher level work.

“scale” was not included on disk at time of writing

so there was no response to that command.
