Background: I believe that the Alka seltzer that was put in the warmer temperature water is going to fizz faster than the Alka seltzer that is put in the cold water. The higher the temperature the more molecules move faster and the colder the temperature the slower the molecules move.

I believe that the temperature that the water is going to greatly affect how fast the alka seltzer will dissolve, because of my research I know that the water with the hotter temperature will dissolve the fasted due to kinetic molecular energy. Kinetic Molecular energy is a behavior of matter in which the kinetic energy and how fast the molecules move, is based on the temperature

Hypothesis: If I dissolve one Alka Seltzer tablet into a warm glass of water and one tablet in a cold glass of water, than the tablet that was placed into the warm water is going to dissolve at a quicker rate. The higher the temperature, the faster the molecules move, the colder the water, the slower the molecules move.]]> 2019-02-06 19:22:18 UTC https://padlet.com/k_wakefield/qrk2rrcpwwq8/wish/328451826 k_wakefield https://padlet.com/k_wakefield/qrk2rrcpwwq8/wish/328458099 Materials:  Alka Seltzer Tablets (9), Glass cup,  Stop watch, Water (Three different temperatures.)

Procedures: 
1)  Prepare materials  that are needed for testing procedures
2) collect the alka-seltzer tablets for the experiment
3) take your glass and fill it with ice water
4) take one whole tablet of alka seltzer and place in in the ice water.
5) Time how long it takes for the tablet to fully dissolve in the water with the stopwatch, make observations on what happens.
6) repeat this process two more times.
7) Dispose the ice water and pour in room temperature water.
8) Place one whole alka seltzer tablet into the glass.
9) Time how long it takes for the tablet to fully dissolve in the water with the stopwatch, make observations on what happens.
10) Repeat this process two more times.
11) Dispose the room temperature water and refill the glass with warm water.
12)  Take one whole alka seltzer tablet and place it in the water.
13) Time how long it takes for the tablet to fully dissolve in the water with the stopwatch, make observations on what happens.]]> 2019-02-06 19:32:46 UTC https://padlet.com/k_wakefield/qrk2rrcpwwq8/wish/328458099 k_wakefield https://padlet.com/k_wakefield/qrk2rrcpwwq8/wish/328459261 Observations and Data Collection:
Control: Size of tablet and amount of water.
Independent variable :Room temperature water
observations: has lots of bubbles in beginning slowly goes away as the tablet gets smaller. tablet is dissolving at a fast rate. sank to the bottom at first and then floated to the top. tablet started to break off into tiny pieces. makes loud fizzing noise. water has different scent than before.
Time 1: 52 sec.
Time 2: 53 sec.
Time 3: 51 sec.
Dependent Variable 1: Warm water
Observations: Water was foggy before the tablet was put into the water. once tablet was place it sank to the bottom then after a couple seconds it floated to the top once it got smaller.could hear loud fizzing noise. not may bubbles a the bottom of the glass. Bubbles were bigger and moving at a faster rate. Fizzing noise was much louder and faster. tablet started to break off into small pieces. water has different scent than before.
Time 1: 37 sec
Time 2: 39 sec
Time 3: 38 sec
Dependent variable 2: Ice water
Observations: fizzy. ice prevented it from ever sinking. softer fizzing noise. bubbles moving at a slower rate. tablet started to break off into smaller pieces after a while.water has a different scent than before.
Time 1: 91 sec.
Time 2: 110 sec.
Time 3: 107 sec.

In the first trial for every water temperature the fastest time was with the warm water at 37 seconds. This evidence supports my claim because the warm water had the fastest time out of all three temperatures. My control for this experiment was the size of the tablet and the amount of water i was using. Both of these things stayed the same and never changed throughout the experiment. My Independent variable was the room temperature water cause the water is at a normal temperature and won't change the tablet to dissolve at a slower or faster time. my dependent variables or the things that changed and affected my experiment were the warm water and the ice water. both of these changes cause the tablet to dissolve at 
either a really fast rate or a very slow rate.

Conclusion: In Conclusion I know that my Hypothesis was correct that the alka seltzer that is placed in warm water will dissolve the fastest because of kinetic molecular energy. and that the alka seltzer placed in cold water will dissolve slower.]]> 2019-02-06 19:38:28 UTC https://padlet.com/k_wakefield/qrk2rrcpwwq8/wish/328461136
