Measurement

1. Measuring Tiny Objects

Background: The larger the number of particles measured, the more accurately one can determine the measurements of a single particle.

Purpose: to determine the thickness of a tissue

Materials: A box tissues, metric ruler, calculator

Procedure:

1. With the ruler, measure the thickness of a single tissue.

Thickness of tissue = ___________ cm

2. With the ruler, measure the thickness of 50 tissues.

Thickness of 50 tissues = ___________ cm

3. Calculate the average thickness of one sheet of paper.

Equation: thickness of one sheet = thickness of many tissues/ (divided by)

number of tissues

Thickness of one sheet = _________

4. Which measurement did you feel most confident with thickness of one tissue,

or the thickness of 50 tissues? ______________________

4. Write a few sentences on what you learned about measuring small objects. How can you compare it to measuring large objects?

2.This handout is designed for an Age group of, 14 and up.

The children should observe a result that when measuring small objects, such as the thickness of a piece of paper, it is much easier and accurate when you measure more and calculate to find the single answer.

Broken rulers, errors with calculator, or not being able to read a ruler are all things that could possibly go wrong. I can deal with all these things simply because a ruler can be fixed, you can get a new calculator, and you should know how to read a ruler.
