Which Rocket Flies Higher?

An 8th grade science fair project can be very stressful for it needs a lot of research and experimentation. However, there are also types of projects which are the winning types yet not that hard to conduct. An example of this is the Rocket Can and the analysis on which makes it fly higher.

PROBLEM

Which flies higher,  a can rocket fueled with vinegar or a rocket fueled with baking soda?

HYPOTHESIS

A rocket made of vinegar may fly higher but it still depend on the results.

MATERIALS

  • Baking soda
  • Vinegar
  • Meter stick
  • Empty balloon
  • Soda can
  • Chopsticks
  • Thin cardboard
  • Top of a plastic soda bottle

PROCEDURE

  1. The can is needed and will serve as the base.
  2. The cardboard should be cut out into a pair of wings.
  3. Paste or glue the chopsticks to the “wings” for support.
  4. Leave some of the chopstick sticking out on the end of the wing.
  5. Poke holes on both sides of the soda can, and put the chopsticks into the holes.
  6. Paste or glue the wings on.
  7. Cut of the bottom of the soda can and place the empty balloon inside.
  8. Pull the nose of the balloon out the top hole of the can.
  9. Next, glue the top of the soda bottle on the cut out side of the can.
  10. For the rocket to launch, you first need to pour in the desired amount of baking soda into the balloon.
  11. Then, quickly pour in the vinegar and close the nozzle of the balloon. Shake up your rocket and let it fly.
  12. Next, do the same with the vinegar.
  13. Record your observations.

RESULTS / ANALYSIS OF DATA

Based on the results, you will be able to see which rocket flies higher.

CONCLUSION

On this kind of project, you will be able to compare which flies higher, a rocket can with baking soda or a rocket can with vinegar. Creativity is really a big help in producing a winning 8th grade science project.
