Myth


The myth I chose is Exploding Jawbreakers, which is testing that if you put a jawbreaker in the microwave, it will exlpode.

QUESTIONS

1) How does a microwave work?
Microwaves use various combinations of electric circuits and mechanical devices to produce and control an output of microwave energy for heating and cooking.
2) What kind of energy does a microwave give off?
The microwave gives of radiation energy.
3) What happens to sugar (sucrose) when it is heated?
The carbon atoms react with oxygen to form carbon dioxide (CO2) and water (H2O). When sucrose is heated quickly it combusts completely, If sucrose is heated gradually in air, it goes through a complex process from melting to decomposition.
4)The particles or molecules in a gas are separated with not regular shape, the liquids are close together with no regular arrangement, that solids tightly packed, usually in a regular arrangement. Gas particles vibrate and move freely at high speeds, liquid particles vibrate, move about and slide past each other, solid particles vibrate, (jiggle) but generally do not move from place to place. gas assume shape and volume of the container its in, liquids assume part of the container's shape, of which it occupies, solids contain their shape no matter what container they are in, and must be able to fit in the container. The kinetic energy in a gas is the greatest of the states of matter. Because of this increased kinetic energy, gas atoms and molecules tend to bounce off of one another, more so as the kinetic energy is increased. The kinetic energy in a liquid is greater than that of a solid, but less than that of a gas. A liquids atoms/molecules are "slippery"; that is, they slide over one another, allowing the liquid to flow. In the solid phases of matter|phase of matter, atoms have a fixed space|spatial ordering; because all matter has some kinetic energy, the atoms in even the most rigid solid movement|move slightly, but this movement is "invisible".
5)The container holds in the pressure, lets it build up and ten bursts out or cumbusts. It's related to a jawbreaker because the sugar melts inside the jawbreaker, then melts the coating that holds the sugar in from the inside, and lets out the pressure that was building up inside it violently.



Small Scale Test

Question

Which jaw breaker will have a more "explosion" effect, the whole jaw breaker or the cut in half one?
Procedures

1. Materials

  • School Microwave
  • 6 jaw breakers (small size)
  • Camera
  • Small saw
  • a roll of paper towels
  • science journal
  • writing utensil
  • a cleaning spray to clean up the mess
  • weighing scale

2. Hypothesis and Variables

  • Hypothesis: our hypothesis in that the jaw breaker will have more of an "explosion" effect than the cut in half one because the whole one has the outside complete wich will hold more pressure than the on cut in half.
  • Independent Variable: time in the microwave.
  • Dependent Variable: wether the whole jaw breaker or the cut in half jaw breaker explodes.
  • Constant Variable: the jaw breaker, the microwave, the radiation level
  • Controlled Variable: the jaw breaker that when in the microwave whole and the one that when in the microwave cut in half.

3. Steps

  • Step 1. Get materials.
  • Step 2. Take Jaw Breaker out of package.
  • Step 3. Saw 3 Jaw Breakers in the middle.
  • Step 4. Set one whole jaw breaker in the microwave.
  • Step 5. Set the microwave time for 5 minutes.
  • Step 6. Press Start on the microwave.
  • Step 7. Take out the Jaw Breaker when its done.
  • Step 8. weigh the jaw breaker.
  • Step 9. Record results.
  • Step 10. Repeat steps 4-9 for the other 2 whole jaw breakers.
  • Step 11. Repeat steps 4-10 except this time use the jaw breakers that your sawed in half.
4. Conclusion
  • Claim: The claim was that the Whole jaw breaker as opposed to the cut-in-half jaw breaker would have more of an “explosion”, because it has a complete outside which will hold more pressure than the cut-in-half one. The whole jaw breaker did have more of an explosion effect; it fizzed with white fizz, while to cut-in-half one just burned.

  • Evidence: There was white fizz from the whole jaw breaker, there pop sounds coming from it, and there were crackling sound when I took out the whole jaw breaker. The cut-in-half jaw breaker had a fizzing sound when I took it out, it melted in the microwave without fizzing, and it was very runny. The cut-in-half jaw breaker also .1g after it was melted so some of it probably turned into gas, before the cut-in-half jawbreaker was heated and melted, it weighed .4g. Before the whole jawbreaker was heated and melted or before the “explosion” happened, it weighed 1.1g and now it weighs .9g which is what the jawbreaker weighed after the “ explosion”.


  • Explanation: The reason why this may have happened is because during the caramelizasion process it may have evaporated some of the jawbreaker. When a jawbreaker caramelizes, it turns into a new substance. The sugar or the jawbreaker undergoes a decomposision reaction in whish a single compound undergoes a a reaction which makes two or more products. The jawbreaker was an oxidation-rudection reaction. The sugar wich is C12H22O11 sugar + heat ® 12 C + 11 H2O then undergoes the process and looses carbon which makes it lighter. It is represented in the equation 2 NaHCO3 + heat ® Na2CO3 + CO2 + H2O. The caramel is brown because of the carbon that is there.


Large Scale Test

Question
Will the whole jaw breaker loose weight and or have an explosion effect?
Procedures
1. Materials

  • School Microwave
  • 3 jaw breakers (large size)
  • Camera
  • a roll of paper towels
  • science journal
  • writing utensil
  • a cleaning spray to clean up the mess
  • weighting scale

2. Hypothesis and variables

  • Hypothesis: My Hypothesis is that the large jaw breaker will not explode but will loose weight because the large jaw breaker will loose all the carbon which adds to the weight of the jaw breaker.
  • Independent Variable: time in the microwave.
  • Dependent variable: whether the large jaw breaker will loose weight and or explode.
  • Constant variable: the jaw breaker, the microwave, the radiation level.
  • Controlled variable: The large jaw breaker.

3. Steps

  • Step 1. Get materials.
  • Step 2. weigh the microwave plate
  • Step 4. Take Jaw Breaker out of package.
  • Step 5. Set one whole jaw breaker in the microwave.
  • Step 6. Set the microwave time for 5 minutes.
  • Step 7. Press Start on the microwave.
  • Step 8. Take out the Jaw Breaker when its done.
  • Step 9. weight the jaw breaker.
  • Step 10. Record results.
  • Step 11. Repeat steps 3-10 for the other 2 whole jaw breakers.

4. Conclusion

  • Claim: The claim was that the Large Jaw Breaker would not explode but would weigh less than when it started off, and it did weigh less and there was no "explosion". That was the claim because there was no scientific back round of any sorts about any of the Jaw Breaker ingredients having any flammable reaction with the radiation and heat that the microwave gives off when its on and running.

  • Evidence:

  • Explanation:



Was the myth plausible, busted or confirmed?

There is no evidence that the jaw breaker exploded because, there was no explosion and since the statement was that it would explode of microwaved, to conclude this, the myth was BUSTED.
