Math Standard:
Measurement
Apply appropriate techniques, tools and formulas to determine measurements:
- Solve problems involving scale
factors, using ratio and proportion.
Math Standard: Representation
Create and use representations to organize,
record, and communicate mathematical ideas.
Select, apply, and translate among mathematical
representations to solve problems.
Use representations to model and interpret physical, social, and mathematical
phenomena.

How will
Marci determine the size of craters on the Moon?
Marci can look up the diameter of the Moon (in
kilometers), she can measure the diameter of the Moon in the pictures, and
she can measure the diameter of a crater in our pictures. Marci can then
use this information to set up a ratio to determine the actual size of the
crater in kilometers.

- What physical parameter are you trying
to determine? (in Marci’s case, the size of craters on the Moon)
- What measurements are you making in order
to determine this parameter? (in Marci’s case, the size of craters in a
picture of the Moon)
- After you have made your measurements,
what must you do with these data in order to determine that physical parameter?
(in Marci’s case, she must make the ratio shown above and solve for Crater
Size on the Moon)
- How many significant figures should you
use when you:
a. Write down your measurements?
b. Calculate your results?
- What does the number of significant figures
you use say about the uncertainty in your measurement?
- What will be the best way to present your
data so that people will understand your measurement? Is a graph helpful?
Do you need to show a table?
