For today's class we continued talking about the liquid. Our disscusions are about how we could do our experiments to solve our problem. Right now we are talking about if we were to take away the light, the paper should still be wet. If is wet, we dissproved our hypothesis, but if it isn't wet our hypothesis is correct. As a class, we go on to our fith idea which is the paper obsorbed it. We would do this by measuring the mass of the paper before and after we put the water on it. If it is obsorbing it, then it should be heavier after you put the liquid on it. Before the experiment the paper was 2.8 and the after Jack dropped the liquid on it, the paper got heavier and it was 3.7. Our prediction was that after 8 minutes the paper should still be heavier. At our 4th check it is down it 3.4. At the 6th check it got even lower and it was 3.2.
We our watching a video on how the air is obsorbing the liquid. This guy put a wet piece of paper in a glass contanier with no air and the other just out in the paper. In the end, the one inside of the glass contanier dryed up faster. So what this means is that the air is soaking the alcohol.
Now, the paper went back to it's starting point which is 2.7. This means that the alcohol left slowly, not fast. We know this because each time we checked the mass was going down by either one or two grams. We need to figure out how it was going down slowly. Jack said that it was made up of different things. The smaller parts go first and the bigger go last. They also said that the bigger spots have different parts inside of the alcohol which means that it would take much longer to go.
