    For Good Measure

Materials: ;meterstick ;ruler ;balls

     ;calculator ;balance

    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.

    your guess: __________________

    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!!

    your guess:_____________________

    length in meters:_________________ length in centimeters:____________

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

    your guess: _____________________

    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.

    your guess: _____________________

    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?
