Aspirin (acetylsalicylic acid) is probably the most used and abused non-prescription drug. Using aspirin tablets brought from home, students analyze and compare them with the Brand "X" aspirin included in this Lab-Aid.

They determine the percentage of aspirin and “filler” components in a tablet, check pH and calculate the per aspirin cost. Students draw conclusions concerning which aspirins are better, which are safer, and which do nothing at all. This kit makes science more interesting because it brings "real world" questions into the classroom. Extension activities are possible with this kit.

Note: Teacher and/or students must supply additional various brands of aspirin.
