3Workshop Objectives
- To promote an awareness of the need for
technological literacy - To provide a hands-on demonstration of
mathematics, engineering, and technology for
classroom use - To promote awareness of the connections between
mathematics, science, and technology standards - To provide information about resources available
to support mathematics, science, and technology
instruction
4What is Technological Literacy?
- Technological literacy is the ability to use,
manage, assess and understand technology. (STL,
2000, p. 242) - Change is a ubiquitous feature of contemporary
life, so learning with understanding is essential
to enable students to use what they learn to
solve the new kinds of problems they will
inevitably face in the future. (PS, 2000, p.
20-21) - Students work with scientific investigations can
be complemented by activities in which the
purpose is to meet a human need, solve a human
problem, or develop a product(NSES, 1996, pg.
161)
5Key Ideas
- Technology is the modification of the natural
world in order to satisfy perceived human needs
and wants (ITEA, STL, p. 242). - Technology is essential in teaching and learning
mathematics it influences the mathematics that
is taught and enhances students learning (PS, p.
11). - Any presentation of science without developing an
understanding of technology would portray an
inaccurate picture of science (National Research
Council, National Science Education Standards, p.
190).
6Technically Speaking Report
- As a society, we are not even fully aware of or
conversant with the technologies we use every
day. In short, we are not technologically
literate.

14Rotational Equilibrium- Step One
- Prepare the materials
- Cut 36-inch balsa into three 31 cm (310 mm)
pieces.
15Rotational Equilibrium- Step One
- Mark each piece at the center, 0 cm and 30 cm.
- Tie a slip knot and make a loop in one end of the
thread. - Lasso a piece of balsa. Snug the loop at the
center point.
16Rotational Equilibrium- Step One
- Hold the piece up to see if the balsa stick
balances. If not, balance the piece with small
pieces of tape. - Repeat the balance test for each piece of balsa.
17Rotational Equilibrium- Step One
- Make the weights
- Secure two pennies to one side of an index card
using cellophane tape. - Fold the index card in half with the pennies on
the inside. - Close the index card with tape.
18Rotational Equilibrium- Step One
- Make a loop in one end of the thread using a slip
knot. Cut the thread about 4 to 6 inches (10 to
15 cm) long so there is a loop on one end. - Attach the straight end of the thread to a weight
with a small piece of tape - Repeat for all four weights
19Rotational Equilibrium- Step One
- Attach a weight to each end of a balsa stick and
snug the loops at the 0 cm and the 30 cm marks. - This piece is the bottom beam of the mobile.
20Rotational Equilibrium- Step One
- Attach a single weight to one end of a balsa
stick and snug the loop at the 0 cm mark. - This piece is the middle beam of the mobile.
- Make another just like it for the top beam.
21Rotational Equilibrium- Step One
- Assemble the mobile.
- Attach the string at the center of the bottom
beam to the free end of the middle beam. - Attach the string at the center of the middle
beam to the free end of the top beam.
22Rotational Equilibrium- Step Two
- Predict the balance points for each of the beams
by summing torques (or moments) about the
balance point of each beam. - This sounds difficult, but is actually very
simple!!
23Rotational Equilibrium- Step Two
24Rotational Equilibrium- Step Two
25Rotational Equilibrium- Step Two
- For the bottom beam
- W X W Y, Therefore, X Y
- Also,
- X Y 300 mm. So, by substitution,
- X X 300 mm, or 2 X 300 mm.
- Therefore X 150 mm and Y 150 mm
26Rotational Equilibrium- Step Two
27Rotational Equilibrium- Step Two
- For the middle beam
- 2W X W Y. Therefore, 2X Y.
- Also,
- X Y 300 mm. So, by substitution,
- X 2X 300 mm, or 3 X 300 mm.
- Therefore X 100 mm and Y 200 mm
28Rotational Equilibrium- Step Two
29Rotational Equilibrium- Step Two
- For the top beam
- 3W X W Y. Therefore, 3X Y.
- Also,
- X Y 300 mm. So, by substitution,
- X 3X 300 mm, or 4 X 300 mm.
- Therefore X 75 mm and Y 225 mm
30Rotational Equilibrium- Step Three
- Mark the predicted balance points on each beam.
- Move the support threads to the predicted balance
points.
31Rotational Equilibrium- Step Three
- Raise the mobile, one beam at a time.
- Adjust the positions of the support threads as
needed to achieve actual balance. - Record your results
32Rotational Equilibrium- Step Four
- Analyze your results
- Did the mobile balance at the predicted points?
- Why or why not?
33Rotational Equilibrium- Step Five
- The method we used for solving the system of
equations is called substitution. - The lesson plan also solves the problem
graphically and by the method of determinants.
