surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches.…

The control group was Brawny brand. The experimental group was Bounty, White Cloud, Homestore, Walmart Brand, and Sparkle. First, move one of the brand’s a paper towel sheets to a balance to see what the mass is. Then, take the dropper and drop water on the flat paper towel…
Hypothesis My hypothesis is if the pills are put in stomach acid, then the gelcaps will dissolve the fastest, because gelcaps are just gelatin capsule that hold the liquid inside. So when the liquid is released it will be absorbed faster than the other pills. I base my hypothesis on Gel Caps or Coated? Pick the Right Pill, page 2 that says, “Soft, flexible gelatin capsules hold liquid-which may be absorbed more quickly than regular pills”.…
#1 completed all of the non-gum to gum tests quicker and increased or kept the same score for every set of tests. Test Subject #2 shortened the time between the non-gum and gum tests all three trials, and increased or kept the same scores two out of three times. Test Subject #3 decreased in time every trial and showed a common trend of a decreasement of five…
A 250 ml beaker was filled with 150 ml of a 10% sucrose solution. Then a 1.4 liter Tupperware container was filled with 500 ml of a 1% sucrose solution. Bag A was placed in the 250 ml beaker, and B, C, and D were placed in the Tupperware container. The initial times were recorded for each bag. Each bag was removed from its respective container and weighed every 15 minutes over the span of one hour.…
This slime lab is about how to make slime using water, glue, and borax solution to learn the cross-linking of molecules of glue to the borate ion that formed new bounds to create slimes. In this experiment, the slime, a shear-thickening substance made up by a polymer glue, and a very viscous solution borax. In the earlier observation made, it showed that the combination of glue and water is sticky, and its molecules can easily past one another to make it harder to pour from the bottles. After adding the borax solution, the glue becomes more viscous because the borax is highly viscous. Base on this fact, the hypothesis can be made as, if add more borax solution to the slime, then the slime will become more viscous and firm, as the amount of…

All of these conditions have one thing in common which arise with problems that can happen when we put food in our mouths.…
During this study, the total number of the participants will be evenly divided into two different groups, and both groups will be asked to solve two simple subtraction worksheets. The independent variable of this study is the participants, and the dependent variable is how fast and accurate the participants can solve each of these worksheets. In order to manipulate the independent variable, one group will be given chewing gum while they are solving the worksheets. By providing chewing gum to one group only, this study can help find out whether chewing gum can increase the problem solving speed and accuracy or not. After the participants have completed each of the two worksheets, the time that it took for the participants to complete the worksheet will be recorded on a sheet of paper.…
The effects of gum’s ingredients is an important factor that contributes to how gum flavors affect memory. Sorbitol is the main ingredient…
The purpose of this lab was to find the effect of different types of liquids on the ability for sugar to dissolve. It was predicted that water and rubbing alcohol would dissolve the sugar but vegetable oil wouldn’t. Sugar was stirred into different liquids to see if the sugar would dissolve in two minutes. The data shows that the water was the only liquid that dissolved the sugar. After conducting the experiment, the hypothesis was proven incorrect.…
