Science Presentation Title: Which will go faster Purpose:Controlled Variable(s): Photos/Sketches: Question:Manipulated Variable(s): Data: Prediction:Responding Variable: Conclusion: Materials:Procedure:New Question(s):
Purpose We decided to test this question because we wanted to know if a vehicle with more wheels would go faster or a vehicle with less wheels.
Question How will the standard vehicle’s speed compare to a 2 wheeled and 3 wheeled vehicle’s speed?
Prediction My group predicted that the 2 wheel vehicle would be the fastest!
Procedure 1.Design vehicle, build vehicle, 2.Set up runway, set up falling weight system (16 small washers=1 big washer.) 3.Test standard vehicle. Then 3 wheel vehicle, then test the 2 wheel vehicle. Test 3 times each.
Photos/Sketches These are the materials we used as we tested the three vehicle designs for speed.
Controlled Variables 1.Weight-1 large washer 2. No Load (blocks) 3.Surface-the desk 4.Runway-a distance of 1 meter 5. Falling weight system using 1 large washer as the force to pull the vehicle
Manipulated variable 1.The vehicle shape. 2.The number of wheels(4, 3, or 2).
Responding variable The speed at which the vehicle traveled 1 meter.
Materials 2 wheel vehicle. 3 wheel vehicle The standard vehicle (4 wheeled vehicle). The falling weight system 1 big washer=16 small washers. Data table Stop watch Meter stick Desktops
Photos/Sketches This is the falling weight system that we used to pull the vehicle forward.
conclusion To conclude, our hypothesis was correct because we thought that the 2 wheeled vehicle would go faster then the 3 wheeled vehicle and the standard vehicle. The 2 wheeled vehicle went 1.19 cm/sec, while the 3 wheeled vehicle went 1.43 cm/sec, and the standard vehicle went 1.96cm/sec. We think this happened because there was less friction between the 2 wheels compared to 3 and 4 wheels. We can conclude that the 2 wheeled vehicle went fastest because of our data.
New question(s)… Sammy: If we added blocks would the data change? Blake: How would the vehicles speed compare to the same vehicle but with 1 block load? Anna: What would happen if we took the front wheel of the three wheeled vehicle, using the falling weight system, will the vehicle still work? Anthony L: Will the vehicle go faster if it is going down a ramp or being pulled by the falling weight system?
