My group came up with this hypothesis.
- Particles move faster with air. No air particle get in the way
Then the whole class joined together for a group discussion.
Davis said: Without the air there is more room and less resistance so it leaves the paper quicker. And it turns out it was a lot of group's hypothesises. Just different wordings.
Finley then said that that alcohol is made up of parts, like particles. Any thing that makes stuff up. Particles want to move, they don't want to move. They're naturally in motion.
Finley brought up a group and a single person. The group was blocking the single person from doing what he needed to do. It made it harder for the single person to move through the group.
We proved that the alcohol dried faster in the vacuum.
Finley brought another group up and put a chair and a container of ammonia with a group of people around it. It was a group of about 8-10 people. 4-5 girls 4-5 guys. They were instructed to raise their hand when they noticed something. 3-4 guys raised their hands.
Afterwords, we wrote down this;
- Hands rose very randomly
- In general, spread from middle outwards. (Not a perfect pattern)
- Shorter people got it first.
- JF & KK never detected the smell.
- Papi detected it 3rd.
The particles were explored farther;
- they move freely
- they move in a random manner
- they move in a direction.
- moves at random speeds.
Then we revisited the homework question:
If your mom is making pizza on the first floor and your on the second floor, how do you know what she's making for dinner?
A classmate said that you know what she is cooking because the particles in the food makes the scent.
Class ended soon after that. The homework is posted on Finley website.
