second: unwrap Alka-Seltzer tablets one per trial and three trials per temperature. 
third: drop one tablet into control(room temperature) water while simultaneously starting the timer.
Fourth: Stop timer when the reaction stops and write time and observation in the data table.
Fifth: repeat steps 2-4 two more times with the control for better accuracy.
Sixth: repeat steps 2-4 three times using the variable(s) (cold/hot water)
last: clean the lab station and put ll materials away.]]> 2018-04-13 23:37:44 UTC https://padlet.com/s_brown21/56fi9l3p9cif/wish/251746000 s_brown21 https://padlet.com/s_brown21/56fi9l3p9cif/wish/264934771 I know that a chemical reaction takes place when molecules
(a molecule is a small group of atoms that are bonded together) separate or bond to form a new substance. However a new chemical is not always made. As an  example, if you mix water and sugar a new chemical is not produced the sugar simply dissolves into the water, but it is still possible to separate the sugar from the water again. An example of a chemical reaction I have made in my life is when I make tea.]]> 2018-06-01 02:59:06 UTC https://padlet.com/s_brown21/56fi9l3p9cif/wish/264934771 s_brown21 https://padlet.com/s_brown21/56fi9l3p9cif/wish/264936995 2018-06-01 03:17:56 UTC https://padlet.com/s_brown21/56fi9l3p9cif/wish/264936995 s_brown21 https://padlet.com/s_brown21/56fi9l3p9cif/wish/264938826 In order to test my hypothesis, I took Alka-Seltzer tablets and dissolved them in different temperatures of water. I recorded the time it took the tablets to dissolve. 
The results of my trials indicate that the hotter the water the faster the tablet dissolved. Cold water took over one minute to dissolve the tablet. 
As the data table shows, my hypothesis was correct. The hotter the temperature, the faster the chemical reaction occurred. 
The temperature of the control set and the hot set were not exactly the same for each of the three tests. This irregularity affected the consistency of the results.]]> 2018-06-01 03:39:49 UTC https://padlet.com/s_brown21/56fi9l3p9cif/wish/264938826 s_brown21 https://padlet.com/s_brown21/56fi9l3p9cif/wish/264940518 I learned what a molecule is and that it can separate or bond to form new chemical substances. 
The experiment explains that temperature has an effect on how quickly something can be dissolved.
