Baking soda and vinegar experiment report

  1. 1. Name: Charlotte Class: 5R Date: March 26th 2012Energy transformation: Baking Soda and Vinegar ExperimentWord bank: gravity, experiment, successful, failed, improve, modify, forms of energy, chemicalenergy, kinetic energy, potential energy, gravitational energy, sound energy, thermal energy, lightenergy, elastic energy, chemical reaction, vinegar, baking soda, rocket, carbon dioxide, rocketchamber, gas, thrust, launching pad, forcePURPOSE:To see the energy transformations in the experiment with a rocketpowered by vinegar and baking soda.HYPOTHESIS:I think that the rocket will work on the second or third try and shoot off thelaunching pad quite high. MATERIALS: List materials used in this experiment: Rocket Launching Pad Vinegar Baking SodaPROCEDURE: 1. Scoop (using a small spoon) approximately 4 grams of baking soda into the launching pad. 1
  2. 2. 2. Pour vinegar into the rocket chamber up to the little triangle (about 40-50mL). 3. Put the pad and the rocket together. Do not screw them together too tightly or too loose. 4. Shake the rocket gently a few times. 5. Place the rocket down where it is ok to shoot up into the air and quickly run away so you do not get hit by the rocket. 6. Watch the rocket blast off into the sky. 7. Record what happened.OBSERVATIONS: What did you see during the experiment? Trial 1 Trial 2 Trial 3 Too tight Too loose Not too tight, not Not enough Was shaken too too loose vinegar or baking hard Flew up high soda 2
  3. 3. Draw and label a diagram of the experiment. 3
  4. 4. CONCLUSION: Explain the experiment using vocabulary provided in theword bank.In this experiment, we were successful and my hypothesis was correct, asthe rocket was able to fly off from the launching pad (unfortunately it failedour first and second try).I found out that if you screw the rocket to the launch pad too tight, it is hardfor the rocket to launch; if you screw them together too loose, it will comeapart very quickly.Each and every time, we had to modify our way of doing the experiment,so when we made a mistake, we could improve our chance of succeeding.When the vinegar is mixed with the baking soda in the rocket chamberthere is a chemical reaction that produces carbon dioxide. The chamber istoo small to contain it all so it has to escape through the hole in the bottomof the rocket. The force of the gas pushing against the pad as it escapesprovides the thrust which launches the rocket from the pad. So chemicalenergy has been converted into kinetic energy. The rocket does not haveenough force to escape the earth’s gravity. After it reached about 15metres in the air it turned started to fall. As it fell it got faster due togravitational energy. 4
  5. 5. Draw a flow chart to show Energy Transformation in this experiment.Use the vocabulary from the word bank. Kinetic Energy Kinetic (Shake the (Scooping the rocket) powder and vinegar) Kinetic Energy (The Chemical (The rocket shoots up vinegar and baking into the air) soda make a chemical reaction) Sound Energy (The Gravitaional Energy noise "pop" that it pulls the rocket makes down 5
