    Conclusion: 2013: Our hypotheses were incorrect except for Group 5. Our guesses were greater than our results. Most of us achieved saturation at 6 spoonfuls. Two groups put all of their salt in at once, which was too much for the water to achieve correct saturation. These groups had to redo the experiment. In the future, these groups in particular will pay closer attention to the directions.

    2012: Our personal hypotheses were incorrect. Most of us thought it might achieve saturation at around 3 or 4 spoonfuls. We found out that on average, it took 5.6 spoonfuls. Most groups reported no unusual variables, but we are assuming everyone filled their spoon in the exact same manner at the exact same height. The number of shakes per bottle may have also affected our results. Everyone should have shaken the bottle the same number of times. One group reported that water kept escaping from the bottle during shaking. That would be an added variable, too. Next time, we would be more diligent in making sure that ALL of the variables were the same, including spoonful level, shaking, and tightened bottle caps.

    Saturation
    A solution is saturated when as much solid material as possible has dissolved in the liquid.
    Salt
    Kosher salt
    Dissolve
    When a material that's added to a mixture seems to disappear

    Day 1: Reaching Saturation with a Saltwater Solution
    Question: How many spoonfuls ofmuch salt did it take beforecan we dissolve in 50 ml of water became saturated?before achieving saturation?
    Hypothesis: IWe think it will take __ spoonfuls of salt will saturate 50 ml of water. Ito achieve saturation. We will know the water is saturatedwe are correct when we count the number of spoonfuls of salt no longer dissolves.it takes to reach saturation and that number matches our HYPOTHESIS.
