My manipulated/responding variable, & control??

I'm doing a science experiment, with the problem being


';Which liquid dissolves Alka-Seltzer the fastest?';


I'm using Dr. Pepper, Coke, Pepsi, and Root Beer, along with water.


Other materials are stuff like plastic cups, stopwatch, etc..


What would my manipulated and responding variables be? Also, what is the control?





Thanks, and sorry, this stuff always confuses me.My manipulated/responding variable, %26amp; control??
Your manipulated variable would be the liquid and the responding would be the time it takes to dissolve. Presuming your using a constant amount of Alka-Seltzer for each liquid.





Your control is going to be the dissolve in water I would think.
