During the class room demonstration, I used five skills. Scientists use everyday to study the natural world. I observed the Enigma Box from the out side and in the demonstration. I made a model of what the Enigma Box looks like from the outside. I also predicted what was in side of the box. Even though those were only three skills, there are two more; which are classifying and inferring. Also the scientists all around the world need these skills to complete and succeed in their studies in the natural world.
In the class demonstration, I observed three actions. My first observation was when Mrs. Casey poured 250mil. of yellow solution into the Enigma Box a slow but steady drip started into the cup. My second observation was when Mrs. Casey poured 50mil. more into the Enigma Box, a faster and more rapidly drip accrued into the cup. But when Mrs. Casey poured 150mil. more yellow solution into the box the yellow solution drained out of the box and into a cup.
My prediction on what is inside of the Enigma Box is a sponge. I think a sponge is inside of the Enigma Box. So from the inside it looks like a black, shiny, hard box. and on the bottom of the box is a sponge. I think the sponge is blocking the tube that drains all the water out of it. Since the water was dripping I believe the sponge soaked up the water and didn't let it out very fast . But when more water was added the sponge couldn't hold anymore water and it started to drain out.
To find out that my prediction was wrong after the demonstration. Mrs. Casey told us what was really inside of the Enigma Box and it wasn't a sponge. There was really a tube that was folded together, one of the ends was at the bottom to get the water and the other where the water drained out. This is how the experiment worked, when 300mil. of water was poured in the pressure from the water and air pushed some of the extra droplets from the other classes out of the box into the cup. That was why there was a slow steady drip. But when 150mil. more was poured into the box the water line reached past the bend in the tube. With gravity and pressure the water that was being poured in started to drain out at the bottom of the tube and into the cup.
