Title: Learn to Measure in Metric
Problem: What is the basic unit for mass?
What is the basic unit for liquid volume?
What is the basic unit for distance or length?
Hypothesis: Answer the above questions, use complete sentences.
Procedure:
Part 1 Measuring length and Area
1. Measure the length of the room in meters, to the nearest tenth of a unit. Record in
table. Include units!!
2. Measure the width of the room in meters, to the nearest tenth of a unit. Record in
table. Include units!!
3. Use a calculator to calculate the area of the room. Area = Length x width.
Answer units are squared. Record in table
4. Convert your length and width measurements of the room into cm, record in table
and then recalculate the area. Record in table.
5. Measure the length, width and then calculate the area of the top of a desk. To the
nearest tenth.
Record Data Here
Object
Length
Width
Area
Room
Room in cm
Desktop
6. Find the height of the room. We will use this number later. Record here Include
units!!
Room height
Part 2 Finding Mass
1. Measure the mass of the container at a lab station. Record in table using correct
units.
2. Fill the container with water.
3. Find mass of the container and the water. Record your data.
4. Calculate the mass of just the water. Record data in table.
5. Convert each of your measurements to mg and record.
Part 2 Record data here
Object
Mass
Mass in mg
Container 1
Container and
water
Just water
6. FILL IN THE BLANK.
The basic unit for mass is a ________________.
Part 3 Liquid Volume
1. Devise a method to find the exact volume of water that could fit into the
container. You may use any of the tools at your table. Explain your method here.
Give step by step directions:
2. Carry out your plan and record in table using correct units.
Volume
Water in
container
3. FILL IN THE BLANKS.
The tool used to measure liquid volume is called a______________
________________.
We always read the graduated cylinder at eye level at the lowest part of the
___________________(fancy word for curved surface).
The BASIC unit for liquid volume is the __________________, however, most
of our experiments call for much less water than that so we will most likely be
using____________________ as our units.
Part 4 Finding Volume of a SOLID
1. Define Volume (you should have this in your notes somewhere):
Object
Container
Length
Width
Height
Volume
2. Using a ruler, measure the length, width and height of your container and record
in table below. Use and record the units you used to measure it in the table below.
3. Use the equation for the volume of a solid to calculate the volume of the
container. Hint: V=L x W x H
USE AND RECORD CORRECT UNITS above!!....Check with instructor!
Part 5 Understanding Capacity
1. Use the Internet, Google the definition of the capacity of a container.
Define Capacity (include the example sentence given in Google):
2. Explain how you can find the capacity of your container and how it may be
different from the volume of the container you calculated above.
Check your answer with instructor.
3. Calculate and record the capacity of the container in the table below.
Object
Container
Length
Width
Height
Capacity
4. Using data from Part 1, how could you find the volume/capacity of the
classroom?
5. Calculate the approximate volume of the classroom. Show your work, record and
circle answer here (Include Units!!!!):
6. FILL IN THE BLANK:
The units for solid volume/capacity will ALWAYS be_________________.
Part 6 Solid Volume and Liquid Volume
1. Look back at Part 3 and record the volume of the water in the container in the
table below. Include Units!!
2. Look back at Part 5 and record the capacity of the container you calculated in the
table below.
Part 3 Volume of water
Part 5 Capacity of container
3. Do you think these two numbers are related? Explain what you think and why.
4. From this information, what is probably true about the units in mL for liquids
and cm3 for solids.
Conclusions:
Explain how you measured everything you recorded. Explain the use of the proper tools
and units.
Record any errors you encountered.
Explain something new you learned from this lab.
