Learning to Measure
Matter comes in all shapes, sizes and weights. Lets learn some methods to measure some common objects by following this activity.
Objective: To explore the length of different objects in everyday life.
Materials Needed:
Materials Needed:
 ruler (to measure small items)
 tape measure (to measure larger items)
 pencil and paper
LENGTH: Length is the distance from end to end.
Length also means the longer distance across. Take for example a cardboard box. There are three measurements of the box: length, width, and height. The longer side is the length of the box. The width is the smaller distance across. The height is the vertical (updown) distance.

Using a Ruler
Find a ruler around the house. Notice on one side of the ruler, the numbers are closer together, that side of the ruler measures length in centimeters. Notice on the other side of the ruler, the numbers are farther apart, that side of the ruler measures lengths in inches.

Look at the picture below. The fork is next to the inches side of the ruler. The “pokey” side of the fork is at one end of the ruler (the “0” mark) and the other end (the handle end) is where you read the measurement. Can you figure out the length of the fork?
If your answer is 8 inches, that is correct!
YOUR TURN
Using your ruler, measure the length of a fork from your kitchen. What is the length in inches and what is the length in centimeters?
Find something around the house that you can measure with your ruler. What is its length in inches and what is its length in centimeters?
CHALLENGE: What if your object is longer than your ruler? How will you figure out is length? (without using a tape measure.)
*Challenge  please write your answer and observations in your journal

USING A TAPE MEASURE
A tape measure has a little rightangled "hook" at the start ... you can use this to hold on to one edge while you pull the tape measure to the other edge. Make sure you measure straight across (or straight up and down).
Assignment 1
Note the result in your Journal. Also write down how you did the measurements.
Assignment 2
Fill in this table. For each object, first take a guess on its length. Write down your guess in the “Guess” column. Then measure the object using either your ruler or measuring tape. Don't forget to write the units (in. for inches or cm. for centimeters). Find three more objects to guess and measure.
