Tool and Technique Stations
• Instructions: Read the task card at each station carefully,
and then do the activity.
• Reminder: Use our group procedures. You must work
with your group; you will move through the stations
together. Only one group may be at a station at a time.
You may do the stations in any order.
• You do not have time to socialize with your group. Work
seriously and responsibly through the stations. If you
reach a point at which you cannot get to another station
because they are all in use, you will need to wait quietly
and watch until that station becomes available.
Length Station
• and calculation of volume
What’s important when using a ruler?
• Measure from the ZERO, not the edge of the ruler.
How can you find the volume of a box?
• Use a ruler to measure length,
width, height.     
• Multiply l x w x h.
• How can you find volume of
some irregularly-shaped
solids?
• by displacement of liquid
– (the difference)    
Volume Station—Graduated Cylinder
What is this?
What shape is it?
What is it for?
Describe the markings.
•graduated cylinder
•measuring volume (in mL)
• cylindrical
•lines go up gradually from
bottom to top
How do you use it?
• Read at BOTTOM of
meniscus (curve).
• (You must move your
head.)
What’s different about
these graduations?

• Multiply l x w x h.
• How can you find volume of

solids?
• by displacement of liquid
– (the difference)    
What’s important before measuring by
displacement?
• Most objects should not
be placed in a graduated
cylinder.
– Help me! I’m stuck!
Mass Station—Triple Beam Balance
What is this? What is it for?
• triple beam balance
• measuring mass (in grams)
How do you use it?
--like Goldilocks
• Put all 3 riders at zero.
• Put object on the pan.
• PAPA—Start with Papa rider. Move Papa too far
to right, then move it one back.
• MAMA—Do the same for the Mama rider.
• BABY—Slide the Baby rider until it is just right.
• Add the 3 measurements (Papa, Mama, Baby)
together to get the mass in grams.
