=Two Types of Experiments Extension= The purpose of the experiment was to determine what type of paper airplane flies the best. The experiment was a comparison and it was comparing the types of planes and how well each plane flies. The control for the experiment was the arrow as it was the most commonly used and made paper airplane. The independent variable was the type of plane we used. The types of planes we used were the arrow (control), the bullet, and a stealth wing. The dependent variable was how long the airplane flew in the air in seconds. The method we used was to through the paper airplane at shoulder height and record the time it stayed in the air and did that to each plane 3 times. The results were that the arrow stayed in the air the longest with an average time of 2.42 seconds and in 2nd was the stealth wing with an average time of 1.83 seconds, and lasts was the bullet with an average time of 1.63 seconds. = = The purpose of the experiment was to determine was type of rubber band flew the furthest. The experiment was a comparison and it was comparing what rubber band flew the furthest. The control was the light brown rubber band because it was the rubber band that is most commonly used at places like stores to keep the eggs closed. The independent variable was what type of rubber band we used and we used the light brown rubber band (control) the brown band and the white band. The dependent variable was how far the band traveled and it was measured in centimeters. The method we used was to shoot the band at 20cm at shoulder height and record the distance and do that for each band. The results were the brown traveling the furthest with an average distance of 595cm then the white going 580cm and last the light brown going 511 cm.


 * ISP Reflection **

The problem for my ISP was if color affected heart rate, if color affected the amount of voltage produced with a filter, and if color affects choice. In the end the black color increased the heart rate the most, and it did matter with the filters because any filter made a difference because it produced less voltage, and for the last experiment the results were that it did matter because someone would chose a colored object over a white one. These experiment went pretty well, except for the first one because I needed volunteers and not enough people asked to do it so it made it a bit of a challenge. Working on all of the experiments was just a fun experience for future knowledge on things like to write a paper, and how to properly conduct an experiment.

**ISP Job Reflection**

A Neurosis’s job is similar to what I did in my ISP. A neurologist job is to diagnose peoples’ brain to determine how the brain works, this relates because in my ISP I was determining how people reacted to color when they see it and how the reaction begins is through the brain. People in this job department would conduct experiments on the brain, determine how it works, conduct MRIs, and do things like giving a diagnostics if someone might have a disorder or a part of the brain is not working properly. On an everyday bases a neurologist would conduct MRIs to determine if someone has a disorder or to conduct experiments on how the brain works



=My Model of a Computer=

====My models were a little bit different after the research. After the research I included some parts like the USB's and the other ports as well as other things like a video/graphic card. So of the things that were correctly done by the first attempt were things the the hard drive, RAM, and the processor. In all the mother board was still there throughout.====

Is Rock, Water, or Air Matter? The first experiment was to determine if a rock was matter. To find if something is it needs to have mass and volume. To determine if a rock was these things, we needed material like, a rock, a graduated cylinder, water, and a triple beam balance. To determine the mass we placed rock on the triple beam balance and determine the mass in grams which was 10.9 grams The second experiment was to determine if water is matter. To determine the mass and volume we needed water, graduated cylinder, and a triple beam balance. To determine the mass you needed to determine the mass of the graduated cylinder then subtract the mass of the graduated cylinder with water which left us with 100 grams. With in those 100 grams it took 100 mL. The third experiment was to determine if air is matter. The material used was a balloon and air and a triple beam balance. To determine the mass we took a balloon filled with then subtracted the mass of the balloon without air which ended with 1.7 grams. To determine the volume we found the area inside the “sphere shape”.


 * Salt **

The chemical formula for salt is NaCl which means it has one sodium and on chloride atom to create a salt crystal. What a salt is and means that it is an ionic compound reaction between an acid and a base. Crystals are building blocks for protons, neutrons, and electrons that can be added and added to make the crystal larger. Salt is a compound because it is 2 atoms together made by that reaction. Other types of salt include things like potassium salt, calcium carbonate, and sodium acetate.

Separating; A Salt-Sand Mixture To conduct the experiment we first needed to add water in the cup with the salt and sand in it. Once the water was in the salt-sand it was mixed to get some of the salt dissolved in the water. Once the salt was partly dissolved it was put on a hot plate at 250 degrees Celsius. Once the water boiled all of the salt dissolved in the water leaving the only thing to see was the sand. Then the salt-water and sand was put through a filter to remove the sand and leave the salt-water. Then the sand in a filter was dried/evaporated so that there was no water absorbed in the filter to get the original weight of the filter. Then the dried filter was placed on a triple beam balance and weighed and then removed to get the weight of the sand with the filter. After the sand was removed from the filter and then weighed to find the weight of the sand. Going from the sand now to the salt-water, the salt water was evaporated on a hot plate at 100 degrees Celsius. After the beaker with the salt because the water evaporated was measured and then rinsed out to get the weight of the beaker and then subtracted from the salt and beaker, to get the salt. At the end of the experiment the salt was 2.4 grams and the sand was 3.6 grams. This ended up because the Weight of the beaker was subtracted from the beaker, and the beaker with the salt or sand to get the total weight.
