For each group of
3 Student Activity Sheets for Learning Experience 4 (Please see PDF
A box filled with: a cube (eg die), a thin rectangular prism
(eg domino), a thick rectangular prism (eg wooden block), a small wood
cylinder, a large wood cylinder, a small plastic cylinder, a large plastic
cylinder, a washer, a marble, a ping pong ball, a cone, a pyramid, a right
scalene triangular prism, a right isosceles triangular prism, an isosceles
triangular prism, a plastic cube, a spool, and a pecan.
A mini-lesson on diameter, radius, and circumference of a
circle may assist students in completing this learning experience. Several
questions on the Student Activity Sheet (Please see PDF
) provide a
checklist for students to mark which scale on the math ruler they are to use.
Choose the measurement scales students are to use prior to them completing
Students will use the math ruler in a particular scale to
find the accurate measurements of the diameter, radius, and circumference of the spheres provided.
will use the math ruler to find the diameter, radius, and circumference of the
spheres and use the formulas to find the surface area of the spheres.
Students are to use the math ruler to find the diameter, radius,
and circumference of the marble and ping-pong ball. Students then use the formula 2?r2
to find the surface area for each sphere. Using the formula 4/3?r3
students find the volume of the spheres. Students then focus on the ping pong
ball. To find the volume of the air inside the ball, we must first subtract the
thickness of the plastic from the ball’s diameter. Plastic = .5 mm thickness
We multiply .5 by 2 because we must account for both sides
of the ball. If using the centimeter scale, the Diameter = 3.5 – 1 mm = 3.4 Radius
= 3.4 + 2 = 1.7 (use this in volume formula) All data is to be recorded in the
tables provided on the Student Activity Sheet for Learning Experience 4 in the
Intermediate Level Measurement Student Activity Book.(Please see PDF
To find the volume of the plastic, students would subtract
the volume of the ball from the volume of the air.
Ideally, to measure these objects, the Vernier Calipers
would provide the most accurate measurement. However, students will not
discover this until Learning Experience 7 when Vernier Calipers are used
in-depth. The measurements completed in this learning experience will be redone
with the Vernier Calipers.
