PHYSICS SYLLABUS by CYNTHIA D'SOUZA 
This lesson was created as a part of
the SMART website and is
hosted by the Illinois
Institute of Technology
This is a one year course taking you from Mechanics
through Waves,
Electricity and Magnetism to Modern Physics. The course
emphasises
learning through experimentation with students following the
Modeling Method
developed by Arizona
State University under a grant from the National Science Foundation.

- In the Modeling Method, students design an experiment and
then use the computer interface to gather and analyze the data from the
experiment. Data such as distance, force, velocity, time and much more
all in real-time can be taken through the use of sensors that take the
measurements. Students then construct an accurate mathematical
model of the phenomena. They present their findings in groups of
three using white-boards. The teacher guides student inquiry
with "Socratic'' questioning and remarks with an eye to
improving the quality of student discourse by insisting on
accurate use of scientific terms, on clarity and cogency. This is
accomplished by questioning and critiquing from students and teacher.
This method shows students precisely how to conduct scientific
inquiry systematically.
- Content of the entire first semester course (mechanics) is
reorganized around five basic models to increase its structural
coherence:
LESSON 1
Roller coaster ride

I. . Set mass, gravity and friction at 50% and
leave them
unchanged until otherwise informed. Adjust height of hill 1to be twice
that of
hill 2 . Make height of loop 80% of hill 2.
II. Tap the green button to activate the run. Make sure
the car runs the entire
course, otherwise fine- tune height settings. Once car is
running, tapping
the pause button allows you to read speed values. To answer the
questions, pause
the car at the points mentioned in the table.
SPEED OF CAR AT:
| |
HILL 1 |
HILL 2 |
LOOP |
| TOP OF |
|
|
|
| BOTTOM OF |
|
|
|
- Make a conclusion about the speeds from Row 2 of table
- Why is the speed reading greater at top of hill2 than hill1?
- Where does the car have maximum kinetic energy( KE), potential
energy (PE)?
- Write a paragraph using the words, speed, KE, PE,
Conservation of energy, to describe the car's run from start to
finish.
- The variables we have the power to vary( even though we
kept them fixed) are called the independent variables. List
them.
III. Reduce friction to 25%.Explain what changes, if
anything.
IV. Increase friction to 75%. Freeze the car at top of
hill 2.
Compare the speed there with that of the corresponding previous trial
(Table).
Explain.
V. What is the result of increasing the value of
gravity?
Progressively increase it to 75%, 100% and note what happens each time.
VI. With gravity set at 75%, what changes can you make
(if any)
to the values of friction, speed, mass to make the car run the entire
course? Explain.
