    as they gptgot bigger. And that's because they really didn't get any bigger. Maybe a few centimeters, but not enough to make an actual explosion. As for the different brand, the one ketchup which DID have High Fructose Corn Syrup, seemed to have a bigger mass in its balloon. I'm assuming, HFCS affects how big the balloon gets.. But I'm not so sure as if right now.

    Constant variable~ The brands of ketchup used.
    Hypothesis~ If we put a brand of ketchup in a flask then will it cause an explosion ON ITS OWN because the gasses of its self mixed and caused a chemical reaction.

    2 brands of ketchup
    1 graduated cylinder
    2 flasks
    2 balloons
    your journal
    a pencil

    Procedure~
    -Small1) Open the bottles of ketchup
    2) Gently 'dump' one brand into the graduated cylinder
    3) Measure out 10mL
    4) After you have 10mL of ketchup in the flask, pour the ketchup from the flask and into one of the flask.
    5) Put a balloon over the top of the flask
    6) Repeat steps 2-5 for the OTHER brand of ketchup
    7) Observe ow big the balloon gets over the next course of the week

    Scale Conclusion:Conclusion~
    Nothing really happened in either flask. The only interesting thing, was when the ketchup separated from the oils. You could barely notice the balloons as they gpt bigger.

    Evidence: The sugar was a solid. Solid bonds are stronger than their kinetic energy of there atom. The atoms are locking into their crystal lattice postions. When it melts, liquid atoms/molecules, have sufficient Kinetic Energy to overcome the chemical bonds that hold them in their crystal lattice, and move independently. Yet they don't have enough energy to seperate completely from their atoms. The gas that it gives off has so much Kinetic Energy that the molecules bounce all around, but repetedly collide with one another.

    we would measure how much the produced. Each person could produce an average of about 3Ml of Saliva

    Dependant variable-If it is possible to eat 3 crackers in 30 seconds
    constant variable- time, amount of crackers, type, people
    small scale conclusion
    It is not possible to eat 3 crackers in 30 seconds.
    Because a cracker can absorb more slavia than you can produce in 30 seconds.
    you can't do it because the cracker will absorb all of your salvia and it will make it so you can't swallow

    being successful. The range of the temperature 65oF to 80oF. The water molecules start to move and get smaller. Because the molecules in the warm water get smaller quicker than the the cold water molecules. A thermometer is a glass tube with a water like liquid that rises if the temperature gets warmer and goes down if the temperature gets colder. To determine which one freezes first you check on the water every 15 minutes until one of them is completely frozen.

    Water(and its chemical Formula): A body of water such as a sea, lake, or river.
    Kinetic Energy: Energy of motion. The energy of an object is the energy it possesses because of its motion.
    Thermometer: An instrument for measuring temperature, often a sealed glass tube that contains a column of liquid.
    Questions to answer:
    1)What is the optimal temperature range for this experiment? (What temperature difference can you have between the two water samples and have this experiment work?)
    2)What happens to water molecules as it starts to freeze? Be sure that you can explain this from the molecular viewpoint.
    3)Why is it that warm water will freeze faster than cool water?
    4)How does a thermometer work?
    5)How will you be able to determine which sample of water freezes first?
    6)How often will you have to “check” the water samples?
