ATTENTION!!

• It is strongly recommended each student obtain project information from the available handout and NOT by word-of-mouth.

WRONGINFO

GOAL 1:Using the instructions provided, design and build an air car that will travel 30 feet and pass through a designated target area.

Materials list

• Electric motor• Propeller• 9V battery clip• One wire lead with two alligator clips

Materials list

• Four wheels 1 3/8” diameter with 3/32” tread width• Two 9” lengths of 1/8” diameter

dowel rod.• Four straws 9/64” diameter X 5”

length.

Construction requirements

• The car presented for the final design must include the electric motor, propeller, wheels and dowel rod provided in class.

• The motor may be connected to a battery however you choose to do so.

• Any type of tape or glue may be used in the construction of the car.

• The following items may NOT be used in the construction of the air car:– Legos, K’NEX or parts from any other construction

sets.– Any parts from a car “kit” (e.g. CO2 car)– Any parts from any type of toy car or model car

Demonstrating Your Car• Five attempts to demonstrate your

car.• Attempts 1- 3 are FREE.• Attempt 4 costs 5% of grade –20 points

• Attempt 5 costs 10% of grade–40 points

IMPORTANT NOTICE

• If on the scheduled day the project is due a student is absent due to a field trip, in-school performance, out of school trip, etc. then the student must demonstrate the car for a final grade the day before.

IMPORTANT NOTICE

• If a student is on a preplanned absence (i.e. vacation, surgery) the day the project is due then the car must be demonstrated the last day the student is in school before the absence begins.

IMPORTANT NOTICE

• If an unplanned absence (i.e. illness) occurs on presentation day, the project will be presented on the students’ first day back from the absence. Students may need to make alternate transportation arrangements for presentation before or after school.

Goal #2: Students will submit either a poster or a PowerPoint as part of their Independent Study.

PowerPoint or Poster

• Labeled digital photograph(s) of car

• Sequence of energy conversions (flow chart)

PotentialGravitationalThe ball starts at the top of

the hill.

   

KineticMechanical

The ball begins rolling down the first hill.

  

PotentialGravitationalThe ball gains gravitational energy as it rolls up the smaller hill.

   

 

 

KineticMechanical

The ball begins rolling down

the second hill.  

 

 

KineticSound

The ball emits sound as it

moves.

KineticHeat

There is friction

between the ball and the

surface.
