Name at least three controlled variables .* AMOUNT OF WATER , AMOUNT OF AVICA - SELTZER , SIZE OF CLASS 3 . State the hypothesis for Activity I as an " if then " statement . IF THE TEMPERATURE OF THE WATER IS INCREASED THEN THE ALKA - SELTZER TABLETS WILL DISSOLVE FASTER 4 . Was the hypothesis proven or disproven ? Explain ." THE HYPOTHESIS WAS PROVEN. EACH ALKA - SELTZER TABLET DISSOLVED FASTER AIS THE TEMPERATURE INCREASED . 5 . Were the results reproducible ? Explain .* YES . THE AVERAGE OF ALL THE RUNS WAS CONSISTENT WITH EACH INDIVIDUAL RUN .` 6 . What variable was not completely controlled during the experiment , and what could have been changed to make this variable more constant ?" THE SIZE OF THE ALKA - SELTZER TABLETS USED WERE NOT EXACTLY THE SAME . USING FULL TABLETS WOULD MAKE IT MORE CONSISTENT ....

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
