One,

Problem: Which Hot wheel car will be the fastest to make it
to the bottom of each ramp, Why? Which tracks will all cars move down
the fastest and which one will they move down the slowest, Why?
Hypothesis: ________________________________________________.
Materials: Hot Wheels cars of various masses, 5 different Homemade
tracks, Stop watches, Meter sticks , Triple-Beam Balance
Procedures:
- Everybody has a job in this one. Look for your first job on the
Job Posting List.
- If you were given the job of "Vehicle Inspector" you and group will
be charge of a car. You must first measure the mass of the car and
then write a detailed description of the car.
- If you were given the job of "Track Surveyor" you will measure the
dimensions of the Track you were assigned and then write a detailed
description of the track.
- Wait for your teacher's instructions.
- After these tasked are completed you will share your findings with
the class.
- After all the data has been shared, you will as groups formulate
a hypothesis to the two-fold problem.
- We will then test the amount of time it takes each car to travel
down the distance of each track at a 45� angle (Run an Experiment).
