The purpose of this experiment was to decide which type of paper (copier, construction, lined) would make a paper airplane fly the farthest. This experiment is a comparison experiment, because we were comparing the different types of paper. The control of this experiment was copier paper, because that is the most normal paper out of all the different types of paper. The independent variable of this experiment was the type of paper used, because the papers I used were all different. The dependent variable of this experiment is how far the plane flies. The method we used to conduct the experiment had 5 steps to it.===== After 3 Trials for each type of paper, we discovered that construction paper flew the farthest with an average distance of 296.67 cm.
 * 1) Make three airplanes out of three different types of paper (construction, lined, copier).
 * 2) Throw each paper airplane at the same distance.
 * 3) Measure how far the airplane flew.
 * 4) Do this 3 times for each paper airplane.
 * 5) Record results.

The purpose of this experiment was to decide how long it took a rubber band stretched at 2, 4, and 8 cm. to hit the ground. This experiment is a comparison experiment, because we were comparing different stretch lengths. The control of the experiment is 2 cm. because that is about how long the rubber band stretches without any force on it. The independent variable of the experiment is the length we stretched the rubber bands, because the length we stretched the rubber band varied. The dependent variable of the experiment is how much time it takes before the rubber band hits the ground. The method we used to conduct the experiment consisted of 7 steps. After 3 Trials for each stretch distance of the rubber band, we discovered when you stretched the rubber band back 4 cm, it flew the longest with an average of 1.46 sec.
 * 1) Stretch the rubber band back 2 cm.
 * 2) Let go, and see how much time it takes before the rubber band hits the ground. Do this three times.
 * 3) Stretch the rubber band back 4 cm.
 * 4) Let go, and see how much time it takes before the rubber band hits the ground. Do this three times.
 * 5) Stretch the rubber band back 8 cm.
 * 6) Let go, and see how much time it takes before the rubber band hits the ground. Do this three times.7. Record results.

ISP Reflection
I was trying to determine whether the temperature of a ceramic donut magnet would affect it's magnetism. I concluded that when a magnet decreased, it's magnetism increased. I thought that my experiment went as well as possible. If I had a way to make the temperatures of the magnet a little more extreme. If I had a little more time, I could continued on an extension experiment. I felt like I was always making new discoveries when working on the ISP. I felt that I not only learned about the temperature affecting the magnet, but that I also learned about magnetic fields and the atoms in the magnet.


 * ISP Job Reflection and Analysis**

The job that I found was most similar to my ISP project, was a Materials Scientist or Engineer. The career choice relates to my ISP project because a Materials scientists builds materials such as metals and magnets. My project was to determine whether the temperature of a magnet effects its ability to pick up paperclips. As a materials scientist, I could make a magnet that works the same in all temperatures. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers usually work regular hours in offices and laboratories. Research and development materials scientists spend much time in laboratories, but also work in offices when they do theoretical research or plan, record, and report on their lab research.



Comparison
The parts of my initial model that I got correct were the door and the handle, as well as the buttons. The parts that I corrected with my research, Were the timer, the cycle chooser, and the start button. The advanced model, has a cycle chooser, which chooses how you want to wash your clothes, a start button, which you press to start the cycle. When your done, the Timer will beep, and you will open the door, and take your clothes out.

Rock
We tested if the rock was matter by weighing the rock on the triple beam balance, then filling the cylinder up to the 80 ml. mark with water. Then we placed the rock in 80 ml of water and measured the displacement of the water. Our results showed that the rock weighed 22.4 g. The rock is matter. The materials used were: Rock, Graduated Cylinder, Water, and a Triple Beam Balance.

Water
We tested if the water was matter by weighing 30 ml of water in a graduated cylinder. We then dumped the water out and re-weighed the graduated cylinder. Then we subtracted The weight of the water minus the weight of the graduated cylinder. The answer was yes, the water is matter. Our results showed that the water weighed 80 ml. The materials used were water, graduated cylinder, and a triple beam balance.

Air
The way we determined if air was matter, was: we weighed the blown up balloon on the triple beam balance, and then we weighed the deflated balloon, and then subtracted the deflated balloon from the blown up balloon. Then we estimated the amount of cubic cm, which was 1200. The materials used were a balloon and a triple beam balance. The air is matter.

Salt Crystals
Representation of Salt Crystal

The chemical formula for table salt is NaCl. It means that table salts atoms are made up of sodium and chlorine. Table salt is a compound because its atoms are made up of two elements. Salt is any chemical compound formed from the reaction of an acid with a base, with all or part of the hydrogen of the acid replaced by a metal or other positive ions. A crystal is any solid consisting of a ordered, symmetrical, three-dimensional clumping of atoms or molecules. Other salts are: Sodium hydroxide, Potassium hydroxide, Lye, Calcium hydroxide, and Magnesium hydroxide.

=Separating Sand from Salt=

Picture 1: Drawing depicting the series of events of our experiment.

In order to separate our sand/salt mixture, we poured it onto a weighing paper, to see how much it weighed on the triple beam balance. Then, we poured the mixture into 100 ml of water, and stir it. Then we placed the beaker on the hot plate, and waited until the salt dissolved into the water. Then we banded a coffee filter to a beaker, and poured the water/mixture into the filter. Then we dried the sand, and weighed it. then we subtracted the weight of the sand from the total weight of the mixture.

In the end, we decided that the sand weighed 3.6 grams, and the salt weighed 2.4 grams for a total of the whole mixture weighing 6 grams. I believe that my experiment went very smoothly and according plan. In the future, if I had to create the experiment again, I would leave the beaker with the sand/salt mixture and water on the hot plate for longer to ensure that the salt dissolved in the water. I would leave it on the hot plate for just the right amount of time so the water doesn't evaporate, but for long enough so that the salt doesn't dissolve in the water.
