GOAL 1:Using the instructions provided, design and build an air car that will travel 30 feet and pass through a designated target area.
9
Materials list Electric motor Propeller 9V battery clip One wire lead with two alligator clips
10
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.
11
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.
12
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. CO 2 car) – Any parts from any type of toy car or model car
13
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
14

15
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.
16
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.
17
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.
18
Goal #2: Students will submit either a poster or a PowerPoint as part of their Independent Study.
19
PowerPoint or Poster Labeled digital photograph(s) of car Sequence of energy conversions (flow chart)
20
Potential Gravitational The ball starts at the top of the hill. Kinetic Mechanical The ball begins rolling down the first hill. Potential Gravitational The ball gains gravitational energy as it rolls up the smaller hill. Kinetic Mechanical The ball begins rolling down the second hill. Kinetic Sound The ball emits sound as it moves. Kinetic Heat There is friction between the ball and the surface. Kinetic Sound The ball emits sound as it moves. Kinetic Heat There is friction between the ball and the surface.
21
