Station #1
1. Measure the length of the
yellow ribbon with metric Ruler
A then with metric ruler B.
Repeat for the pink ribbon.
2. Record data on lab sheet and
answer questions.
Station #2
Sort all of the cards in the stack
under whether they have
1,2,3,4, or 5 significant figures.
Have your teacher check your
work and sign off your paper.
While you are waiting for her,
work on your post lab questions!
Station #3
Measure the volume of liquid in the
two graduated cylinders. Make sure
to have the correct precision (the
correct number of places after the
decimal). Remember you can only
estimate ONE DIGIT past what is on
the measuring equipment. NOTE:
PLEASE DO NOT POUR OUT OR ADD
ANY WATER TO THESE! I NEED TO
KEEP THIS VOLUME CONSISTANT FOR
ALL MY CLASSES!
Station #4
1.
Do the card sort with the white cards. Put the cards
with the metric (SI) units under the word “Metric,”
and the units we use in America under “Standard.”
Have your teacher check your work and initial your
paper.
2.
Use the blue cards of metric prefixes and arrange
them from largest to smallest.
3.
Match the yellow cards to each blue card so that you
can learn the value of each prefix. You may use your
notes if you get stuck.
4.
Check your answers for the blue and yellow card sort
by turning over each match and seeing if it has the
same letter on the back.
Station #5
Sink or Float?
Put each object in the beaker of
water to see if it sinks or floats.
Answer the questions on your
lab sheet.
Station #6
Kelvin and Celsius are the two units
for temperature in the metric system.
Measure the temperature of the
water in degrees Celsius. Write it on
your lab sheet, then convert it to
Kelvin.
Make sure that the switch on the
electronic thermometer is not on
Fahrenheit!
