Procedure (be sure to include units in your answer). You may not use all the objects in your box, but use each one ONLY ONCE!

1. Find an object whose length can be easily measured in centimeters. Measure the

object and record its length.

description of object:________________________________________________

length:________________________

2. Observe the distance from one side of the classroom to the other. Make a guess as

to how many meters you think that distance is. Now measure that distance and

record its length. ONE GROUP AT A TIME!!

length in meters:_________________ length in centimeters:____________

3. Find an object that can be easily measured in millimeters. Measure the object.

description of object:__________________________________________________

length in millimeters:_________________________

4. Find an object that fits easily on the pan of the balance scale. Find the mass of the

object in grams.

description of object:___________________________________________________

mass:________________________

5. Measure the volume of a regularly shaped object. L X W X H

description of object:___________________________________________________

Name ____________________________________________Date _______________Period ____________

volume:_____________________

6. Use the balance scale to find the mass of ball #1. Record that mass in grams. Now find the mass of ball #2. Record that mass in grams.

ball #1 type:____________________ guess: ________________

actual mass #1:_____________________

ball #2 type:____________________ guess: ________________

actual mass #2:_____________________

7. Now take a piece of string and use it to measure the circumference of ball #1 at its widest point. You can do this by wrapping the string exactly once around the ball, then measuring the length of the string. Record your measurement below. Repeat the procedure for ball #2.

circumference of ball #1:___________________________

circumference of ball #2:___________________________

Questions

1. Which of the measurements that you made were most familiar to you?

2. Which of the measurements that you made were least familiar to you?

3. Which of the measurements did you find easiest to make?

4. Which of the measurements did you find most difficult? Why?

5. Look at the measurements that you recorded in question 6 and 7. In what way

are these two balls similar? In what ways are they different?

6. Why do you think, as a scientist, it is important that we have an accurate system

of measurement when doing science?
