Part I: Making measurements using the metric system

CONVERSIONS. Do the following conversions:

253 liters = ___________ milliliters     60 daL = __________ L
0.05 grams = __________ kilograms15 mg =  __________ g
53 milliliters = _________ microliters43 kg = ___________ g
253 milliliters = ________ cubic centimeters4 hm = ___________ m
175 centimeters= _______meters5 g = _____________ mg
  1. Convert the room temperature from °F to °C        70°F = ______________ °C
  1. Convert the body temperature from °C to °F        37.5°C = ____________ °F

You can check your answers with a conversion calculator. Just remember you will not be allowed to use one on the exam!


Measuring Volumes

  1. To practice reading volumes, use this Interactive Activity: Graduated Cylinder Challenge

Tip: For each measurement, take the time to count the number of minor graduations between the major graduations and make sure that you know the value of a graduation (ie: 1ml, 0.5 ml, 0.2ml, etc). Take a screenshot of your completion certificate and paste it here.

Measuring length

Use a ruler or a meter stick to answer the following question. Pay attention to the units!

If you don’t have a ruler, use this online ruler. For your height, don’t miss an opportunity to do a conversion! First, convert your height in inches. Then convert in cm by multiplying by 2.54 (There are 2.54 centimeters in 1 inch). Finally, convert in meters.

  1. What is the width of a notebook sheet? ______________________________ cm
  2. What is the length of your thumbnail? _______________________________ cm
  3. What is the length of a fork? _______________________________________ cm
  4. What is the height of this letter: E ? _________________________________ mm
  5. What is your height? _____________________________________________ m

PART II: Graphing

Remember these basic rules when graphing:

A graph consists of two lines: one vertical and one horizontal. These lines are drawn at right angles to each other and intersect at a point called the origin. The horizontal line is called the x-axis, or independent variable. The vertical line is called the y-axis, or dependent variable.

The independent variable is the value that the experimenter changes in order to perform an experiment. The dependent variable depends on the outcome of the independent variable. For example, if you were collecting data on an experiment that involved plants growth rate in 4 hours and 8 hours sunlight, the time of sunlight is the independent variable, and the plants growth rate is the dependent variable.

When constructing a graph, a test variable is placed on the x-axis.  This is the variable that we have some degree of control over in an experiment such as time, volume, temperature, etc.  The y-axis will contain the resulting values of an experiment, such as height, weight, quantity of product, etc.  After numbering each axis, they are labeled with a description of the variable being tested and the unit and the graph itself is given an appropriately descriptive label.  Do not forget your labeling!!

Construct your own graph using the data set below. Use the graph paper at the end of this report. Be sure your graph follows all the rules.

Hours Spent StudyingExam Grade

Once your graph is complete, answer the following questions based on it:

  1. Which variable is dependent? Why? (Which variable did you control> did you select the time that student spent studying or the exam grade?)




  • Do you believe the line of best fit represents this data accurately? Why or why not?



  • Is the relationship direct or inverse? Why?



  • If a student studied for 2 hours, about what would their exam grade be?
