1. Be sure to have several Pointer
Boxes ( see “pictures”) ready, before the lab.
2. Check to make sure nothing
is broken.
3. Make enough copies of the Station Marker sheets and the Student Lab sheets for the class ( see “diagrams”).
4. Choose several locations
in your room to be your stations.
5. Place a Station Marker sheet at each station,
with North clearly indicated.
6. Place a Pointer Box on
each Station Marker before class starts.
7. Choose an object in your
room to act as your Cosmic ray source ( The clock on the wall is a good one. ).
8. Rotate the Pointer Box so that the folding cardboard
arrow points in the direction of the source.
9. Raise the wooden arrow so
that it points directly at the source.
10. With your Teacher Data ( see “diagrams”) sheet, record the elevation angle and direction for
that station using the protractors on the side of the box and on the Station
Marker sheet.
11. Proceed to another
station and record its elevation angle and direction on the Teacher Data sheet.
12. Do the same for all your
stations.
13. Once the students come to
class, divide them up into small groups ( two or three ) and hand each one a Student Data Sheet.
14. Explain the lab and
announce the first group’s elevation and direction and tell them to record it
on their Student Data Sheet.
15. Announce the second
group’s data and have them write it down on their Student Data sheet.
16. Once all of the data has
been recorded by the students for all the stations, have each group;
a. pick up a Pointer Box
b. place the corner of their Pointer
Box on the center of their Station sheet protractor
c. adjust the elevation angle
d. point the box in the indicated direction.
e. step back
17. Once all of the Pointer Boxes are set, have the entire
class look at where they are all pointing and determine the location of the Cosmic
Ray source.
18. If you prepare data for a
second source location, run the lab a second time and find the second location.
