Remember to create a statement that is able to be tested empirically. If | add an Alka-Seltzer tablet to the hot water, then it will dissolve at a faster rate than the cup with cold or room temperature water. https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 2/14

2/12/24, 9:57 AM carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play Candice Baumert Questions 3. What are the two variables that you graphed? 1. Time tab takes to dissolve 2. Water Temperture. https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 5/14
2/12/24, 9:57 AM carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play Candice Baumert Questions 4. Which is the independent variable? Should it be on the X- or Y-axis? Why? The Independent Variable is the temperature of the water. It belongs on the X axis, because the Temperature of the water is controlled though out the lab https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 6/14

2/12/24, 9:57 AM carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play Candice Baumert Questions 5. Which is the dependent variable? Should it be on the X- or Y-axis? Why? The dependent Variable is the time it takes to dissolve the Alka-Seltzer tablet. It belongs on the Y axis, because the time the tablet takes to dissolve, depends on the water temperature https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 7114
2/12/24, 9:57 AM carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play Candice Baumert Questions 6. Predict how many seconds it will take to dissolve an Alka-Seltzer® tablet in 200 mL of water at the following temperatures. Use the exponential trend line to find the function used in predicting the time. If needed, please refer to the Introduction to Graphing manual for guidance. a. 35°C a) 60 seconds b. 60°C b) 20 seconds c. 80°C c) 10 Seconds https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 8/14
2/12/24, 9:57 AM carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play Candice Baumert Activity 2 Questions 7. List five questions about the rate at which Alka-Seltzer® tablets dissolve if the temperature was held constant and one of the controlled variables was changed. 1. What would happen if | constantly stired that tablets as they were dissolving? 2. What if | added food coloring to the water cups? 3. What if | increased the water amounts from 200ml to 300 mlI? 4. What if | decreased the water amounts from 200 ml to 100 ml? 5. What if | added a salt solution to the water before adding the tabs? https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 9/14

Remember that a hypothesis must be testable with empirical or measurable data. If | add 1 tsp. salt to a cup at room temperature, then the Alka-Seltzer tablet will dissolve faster than the cup with %2 tsp. salt and the cup with no salt https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 10/14

What could have been done in either activity to make the results more reproducible? Tracking the temperature of the room temperture water during each trial. | took the temperature in the beginning and it was 15 degrees celcius, which was consistent with the room temperture readings during part one of the experiment. https://carolinascienceonline.com/#/student/assignments/653543?origin=SUBMITTED&play 13/14
