=Two Types Of Experiments Extension= The purpose of our experiment was to find which type of paper airplane flew the furthest. This experiment was a comparison experiment because the data involved both words and numbers. The control of our experiment was the Arrow plane because it is the normal type of plane. The independent variable was the type of plane and the dependent variable was the time the paper airplane stayed in the air. For our experiment we threw a paper airplane three times then averaged it. Then we did the same thing two more times except with different paper airplanes. The three paper airplanes we tried were the Arrow, the Condor, and the Ball plane. On average the ball plane stayed in the air 38 hundredths of a second longer with an average time of 2.51 seconds of flight time. That was our paper airplane experiment.

The purpose of our second experiment was to see how many rubber bands was the prime amount to shoot. We tested one rubber band two rubber bands and three rubber bands. The experiment was a relationship experiment because the data only involved numbers. The control of our experiment was 1 rubber band because it is the normal amount to shoot. The independent variable was the amount of rubber bands we shot and the dependent variable was the distance it flew. For our experiment we shot three rubber bands three times to see how far they flew. Then we did the same except with two rubber bands. Then lastly we did it with one rubber band. On average 1 rubber band did the best with an average distance of 657 centimeters which was 23.5 centimeters better than 2 rubber bands. That was our rubber band experiment.


 * ISP REFLECTION**

I was trying to figure out which NERF gun was the most accurate out of the NERF Jolt, the Maverick, and the Retaliator. The NERF Retaliator was the most accurate out of the three guns. I think my experiment went well because I got conclusive results that show that the Retaliator was very accurate. I felt very good working on my ISP because it was fun and exciting.

The job that relates the best to my independent science project is a physicist. A lot of things that are involved in my ISP would be part of a physicists job to know. Projectile motion and gravity are just some of the things that were big factors in my experiment and both of those things relate to physics which is what physicists study. One thing a physicist does is study physics. They can also invent things that can help the field of physics learn more about the world and its many unknown things. Physicists explore and identify basic principles and laws governing the motion, energy, structure, and interactions of matter on a daily basis.

Pro Figurine 2: A advanced model of a Microwave There are many differences between the two models of microwaves. For example in the first model I did not realize that there was a device that generated the microwaves all over the Microwave. In the second one I had buttons which could adjust the time and heat of the microwave. I also had a clear door that you could look through to see the food cooking. Those are the differences between the two drawings.

=__//**Proving a Rock, Water, and Air are Matter**//__=

In the first experiment we tried to figure out if a rock is matter. The rock was put on the triple beam balance and its weight was taken. The graduated cylinder was filled with water partially and it was seen how much space it took up then we dropped the rock in there and saw how much more space it took up and that was how many cubic centimeters it was. The rock had a mass of 22.4 grams and a volume of 6.5 cubic centimeters.

In the second experiment we tried to figure out if water was matter. We measured how much a graduated cylinder weighed. We then added 25mL of water and realized it took up space. Then we weighed the cylinder with water in it and realized the water had mass because it weighed more. The water weighs one gram per cubic centimeter. The water takes up 25 mL of space. The water does take up space. The graduated cylinder weighed 94.4 grams.

In the final experiment we tried to figure out if air was matter or not. For the first part we weighed the balloon on a triple beam balance non blown up. We then filled it with air and weighed it and it weighed more. Then we put small blocks in it and realized it took up space.The balloon without air weighed 3 grams. With air it weighed 4 grams. We think it would have a volume of about 1500 mL.

Salt has many interesting things about it and crystals do also, but when you combine them you get a salt crystal! Now first lets talk about salt and the different forms of it. Salt's chemical formula is NaCl which is sodium chloride. In chemistry, salts are ionic compounds that can result from the neutralization reaction of an acid and a base. Now lets talk about crystals. Crystals are solids that are formed by the regular repeated pattern of molecules connecting together. Salt is considered a compound because it takes at least two elements two make it up. One type of salt is Magnesium Sulfate. Another type of salt other than that is sodium carbonate. There are many alkali salts too.

__//**The Separation Challenge**//__

For our experiment what we had to do was figure out how to separate a mixture of sand and salt and make them separate hence the name the separation challenge. What we did at the start was we tried to filter the salt away from the sand by putting the mixture in a filter and pouring water in it so the salt would dissolve and it would be separated. Then we boiled the salt water so the water would evaporate and we would be left with just salt. We also boiled the wet sand to make it dry so then we had just salt and just sand. This worked very well for us because at the end you could clearly see a sand part and a salt part so we knew it was separated. We found the weight of the salt part to be 1.8 grams and the mass of the sand to be 3.2 grams. The salt looked very different after it was boiled because it was very white and crusty. That is what happened in our experiment.
