In this lab, my group and I had to measure the rate a plastic container and its top, would fly off with a different amount of alka seltzer and vinegar. In order to get results, you would need to change the results; if you didn't do this, the results would remain the same. Student B had the best method for this experiment because unlike the other two students, student B changed the temperature variables in order to get different outcomes.
Each particle changed the rate because as the temperature increased, the time the cap came off was at a faster rate. As the temperature decreases, the cap comes off at a slower rate. The more vinegar that is added and the less alka seltzer that is added, causes the cap to come off at a slower rate because the alka seltzer is what triggers the whole experiment.I predicted that the higher the temperature, the faster the cap of the container would come off and the lower the temperature, the slower the cap of the container would come off.
Enrichment:
An example of a catalyst is the catalytic converter in a car. This is coated with platinum to reduce carbon monoxide emissions. Catalysts are used in an industry to speed up the rate of reaction.
