Beach Ball Experiment

In our past experiments and observations we have found that air is in fact matter we know this because air takes up volume and mass. In the beach ball demo, we tested the beach ball without air and the mass was 56.1 grams and then we tested it again with air and the mass equalled up to 56.3 grams. This shows us that air takes up space. In the investigation 1.2, we tested 3 demonstrations. And in the second demonstration In demonstration 2 the cup was put into the water, upside down, the beaker overflowed, and the paper towel that was inside of if did not get wet because the air was already taking up the space in the cup, therefore the water couldn't go inside the same space. In demonstration 1 the cup was placed in the water right side
As the temperature hit the melting point and was slowly rising (2:30 - 0*C, 3:00 - 0*C, 3:30 - 0.5*C, 4:00 - 1*C, 4:30 - 1.5*C = first 5 trials after we lit the flame) the ice started melting. Energy was entering into the liquid as it was melting, which made the molecules able to slowly spread apart from each other. And as soon as the temperature hit the boiling point (15:30 - 89*C, 16:00 - 91*C, 16:30 - 93*C, 17:00 - 93*C, 17:30 - 94*C = last 5 trials after ice hit boiling point) The liquid was started turning into gas, and more energy was entering the liquid as it was turning into water vapor. The molecules started to spread apart faster until they were not touching at all. Our evidence for 1.4 about air is that air temperature can affect things drastically or not, because when things such as ice (A solid) reaches the melting point it turns into a liquid, and then when they reach the boiling point the liquid turns into a gas evaporating into the air. Because we tested this by putting water into a beaker and heating it up and first the ice melted, then boiled. Our science knowledge for this is that when we heated up water the ice in the beaker started to melt and the ice turned into liquid and then when the liquid reached the boiling point the liquid start to boil turning into gas. In demonstration 1 the cup was placed in the water right side up, the water overflowed the beaker. The air escaped the cup which made it able to go fully under the water. So the paper towel ended up getting wet. We know this because when we read pages 28 and 29, we learned that air has volume, and then on pages 32 and 33, we learned that air has mass. Matter is made up of volume and
