for Locating a Spot on a Flat Rectangle or Square: |
|
Mark
a spot on a piece of paper.
 How
would you describe where the spot is located?- What
words would you use to help someone pinpoint where the spot
is located? (up, down, right, left, above, below, north, south,
east, west, top, bottom, hemisphere, etc.)
- How
would you draw a grid system on the page to help you describe
the spot's location?
- What
measurement tools would you use to find the middle of the page?
- What
measurement tools would you use to draw horizontal and vertical
lines that were evenly spaced on the page?
- How
would you measure and draw lines that were equal distances apart?
- How
would you label each horizontal and vertical line to help you
describe where the spot is on the page?
- Which
line is your "equator" dividing the page into two
equal parts? (Helpful Hint: Draw this line with a different
color marker.)
- How
far apart are the lines of your grid?
- How
many horizontal and vertical lines did you draw on the page?
- How
would you describe or label each point where the horizontal
and vertical lines intersect?
-
How did this activity help you learn more about our global grid
system? latitude and longitude lines?
- How
can you use north, south, east, and west to describe where the
spot is located?

| Questions
for Locating a Spot on a Spherical Object |
|
Mark
a spot on a sphere (orange, grapefruit, styrofoam ball, etc).
- What
words would you use to describe where the spot is located?
- How
would a grid system work on a spherical object?
- If
you were going to draw a grid system on an orange, where would
you start?
- Where
is the top of the sphere? Where is the bottom?
- What
measurement tools could you use to find the middle of the orange?
- How
would you measure to find out where to draw a line that would
divide the orange into two equal parts?
- After
drawing a line around the middle of the orange, how would you
describe the two parts?
- Which
of these words would you use to describe the two parts of the
orange: top, bottom, upper, lower, above, below, north of, south
of, hemispheres?
- How
will you decide where to draw horizontal lines so that they are
equal distances apart?
- After
drawing horizontal and vertical grid lines on the orange, what
did you notice? How are the latitude lines different from the
longitude lines?
- Which
horizontal line divides the sphere into two equal parts?
- How
would you describe each part?
- Which
vertical line divides the sphere into two equal parts?
-
How would you describe each part?
- How
can looking at the latitude and longitude lines on a globe help
you draw a grid system on an orange?
- What
challenges did you encounter when you were drawing horizontal
and vertical grid lines on the sphere?
