Hypothesis: If a modified sling shot made of a shoot and rubber bands,then a car is placed in between the rubber band’s arch and the rubber bands are released then the car will go forward.
Procedures: (after car and shoot are made)
- Pull back the rubber bands and hold
- Place car in the middle of the arch made by the rubber bands
- Insert the rubber bands into the notch in the back in the car while holding car in place
- Release the rubber bands by releasing the car.
Results
After 10 test:
8 went straight and traveled over 5 tiles( 160 cm)
1 spun out of control and when about 100cm
1has the rubber bands catch on the wheels and did a 360 in the air
Conclusion
The experiment was successful. After testing the sling shot idea turned out to be the best design so I added to the design to make it work was proficiently as possible. Although a few tests did not show the results needed for full credit, this design is the most promising. The idea of a sling shot design is defiantly what the final design will be bases on.
