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

3
Whats important when using a ruler?

• Measure from the ZERO, not the edge of the ruler.

4
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) ? ? ? ?

5
Volume StationGraduated Cylinder
6
What is this? What is it for? What shape
is it? Describe the markings.

• graduated cylinder
• measuring volume (in mL)
• cylindrical
• lines go up gradually from bottom to top

7
How do you use it?
Whats different about these graduations?
???

• Read at BOTTOM of meniscus (curve).
• (You must move your head.)

9
Whats important before measuring by displacement?

• Most objects should not be placed in a graduated
  cylinder.
• Help me! Im stuck!

Mass StationTriple Beam Balance
11
What is this? What is it for?

• triple beam balance
• measuring mass (in grams)

12
How do you use it?--like Goldilocks

• Put all 3 riders at zero.
• Put object on the pan.
• PAPAStart with Papa rider. Move Papa too far to
  right, then move it one back.
• MAMADo the same for the Mama rider.
• BABYSlide the Baby rider until it is just right.
• Add the 3 measurements (Papa, Mama, Baby)
  together to get the mass in grams.
