Lego pieces that were of varying lengths, that had a defined number of holes in the side of them, rounded ends, and were NOT able to be joined to each other unless other Lego pieces were used are called _____________________. They can be used to form the framework of many of the structures you made for your Lego Balloon Vehicles.

• Bushings

• Pegs

• Axles

• Wheels

• Beams

Your balloon has _____________________________ energy when it is RELEASED- this is the same energy your Lego Balloon Vehicle has as it MOVES down the hallway?

• kinetic

• potential

In our experiment to test the distance of various Lego Balloon Vehicles that we designed, the hallway that we raced each vehicle in would be considered a ___________________________________________ because the size of the hallway was exactly the same for each designer's test of their vehicle's performance

_______________________________________ are round and usually include a rim inside and a tire on the outside. They usually are connected to an axle and spin around the axle.

Because the measurements each designer's LENGTH of their Lego Balloon Vehicle were much different, this served as a _____________________________ in our experiment.

You would see an increase in the _______________________ energy of your Lego Balloon Vehicle AFTER you released your balloon if you insured that your wheels turned freely and had superior coasting ability.

The MASS of each designer’s Lego Balloon Vehicle served as a _____________________ in our experiment, because these measurements were much different for each designer.

What is the best explanation for the role that wheel size played in the performance of the Lego Balloon Vehicles in class?

• Wheel size did not matter at all- it did not help or hurt the performance of the distance each balloon vehicle traveled.

• Generally a large diameter, low mass, thin wheel should have been the best because each turn of the axles was the same for ALL cars- axles were all the same- so if they were relatively lightm bigger wheels would roll farther for each turn of the axles.

• Smaller wheels were the best- the smaller the wheels, the father the car went every time.

• Larger wheels were the best- the bigger the wheels, the father the vehicle traveled every time.

A n example of a _________________________ in our Lego Balloon Vehicles experiment, was that ALL Lego Balloon Vehicles must move ONLY through power of balloon- no pushing or use of other force.
