Today we did the official Alka-Seltzer Lab. We spent time describing scribepost a little bit as well. We split into a few 2-3 person groups and created a lab. We had to include the independant variable is what we can change(concentration, temperature, etc...), the dependant variable which is what you measure, and the control which is what we dont change. We wrote a lab procedure, a conclusion, a hypothesis, and what our variables are. For example, in the experiment in this blog we measured the time it takes for the alkaseltzer to pop, and used crumbled and non crumbled pieces of alkaseltzer. We came to the conclusion that crumbled pieces of alkaseltzer popped faster. We also have to a formal group write up due Monday.
