CONCLUSION QUESTIONS 1) What is the full name of the unit abbreviated “cm?” Centimeter 2) What is the full name of the unit abbreviated “dm?” decimeter 3) Which unit is larger? By how much? A decimeter is larger. by 10 cm.

Mrs. H's comments--One decimeter is equal to 10 cm. So how many times bigger is a decimeter than a centimeter? 1X? 2X? 100X? Your answer is OK if we're talking about one decimeter. What about in general?

4) In this virtual lab, you can’t enter decimal points or numbers smaller than 1. Do you think you could have measured more accurately than this lab allows? Why or why not? No because decimal points are smaller then a real number which makes your answer less accurate.

Mrs. H's comments--think about this: accuracy is a measurement of how close you are to the actual size of the line. The more accurate your measurement, the closer it is to the real length of the line. The more numbers after the decimal, the greater the accuracy of the measurement. So, do you think that you could have measured better if you could zoom in on the ruler? That is what this question is really asking, in a way.
