 * Aim**: To see if 'pukie crunchies' will really make Ms. Lee thinner.
 * Apparatus:** Test tube, 15ml of water, thermometer, clamp stand, Pukie crunchies, toast
 * Diagram**:

Set up an equipment with 15ml water in a test tube and a thermometer inside it. Record the starting temperature around 21 degree Celsius. Set one pukie crunchy on fire(safety flame) and put in under the test tube. When the fire went out, quickly replace it with another pukie crunchie that is lit on fire and do the same with 5 more pukie crunchies. After heating all the pukie crunchies, record the highest temperature.
 * Method**

Get some new water and do the same experiment with a toast. Record the starting temperature of water and the highest temperature of it after heating.


 * Results**
 * Breakfast || Start || End || Increase ||
 * Pukie Crunchies ||  ||   ||   ||
 * Toast ||  ||   ||   ||

Energy(Joules) = Increase in temperature x mass water x 4.8 Energy(Joules) = Increase in temperature x mass water x 4.8
 * Conclusion**

Toast has more energy. Pukie crunchies will probably make Ms. Lee thinner if she eats them for breakfast every morning.
