 * __ Two Types of Experiments Extension __**

Experiment #1: The purpose of this experiment was to see how far each type of paper airplane flies. This experiment was a comparison experiment because we are comparing different types of paper to each other. The control of our experiment was copier paper because it is the most commonly used paper to make paper airplanes. Our independent variable for the experiment was the type of paper used to make the paper airplanes. And our dependent variable for the experiment was how far different paper made into paper airplanes fly. For our experiment we 1st made three paper airplanes out of three different types of paper (copier, lined, construction). Next we flew each three times in a row to see how far they went each time. When we finished we measured all the lengths it landed at wrote them down found the average and then wrote that down too. The copier paper airplane went an average of 315 cm. The lined paper airplane went an average of 573 cm. The construction paper went an average of 431 cm.

Experiment #2: The purpose of this experiment was to see how far rubber bands fly at certain angles which they were shot at. This was a relationship experiment because we are seeing how the angle a rubber band is shot at relates to how far it flies on average. The control of our experiment was 0 degrees; our independent variable was the angle the rubber bands were shot at, the dependent variable was how far on average each rubber band flew at each angle shot. To conduct our experiment we first got three rubber bands and put the ruler that we were shooting the rubber bands from to 0 degrees. We shot three rubber bands at each angle and found the average of each angle they were shot at. We always stretched the rubber bands back 16cm before we shot them. 0 degrees went an average of 480cm. 30 degrees went an average of 623cm. 60 degrees went an average of 480cm.

ISP Reflection

The problem I was trying to solve was the chipping time of pre-made and home-made nail polishes. My conclusion was that pre made nail polishes chipped an average of 22% and home made nail polishes chipped an average of 17%. I felt my experiment went quite well, because I got a full table of data and a shocking but money saving nail polish discovery, well of course having fun along the way. I enjoyed working on my independent science project because you have no one to argue your ideas with, but at the same time it was lonely.

ISP Job Reflection

Having a career as a chemist would be the most accurate job decision once completing my ISP. This job relates to my ISP because in my ISP project I mixed chemicals as a chemist would, I also found a way to mix chemicals that is safe for a home environment, I tested chemicals to make sure they were safe for others to use. I also tested these chemicals to see if there would be any malfunctions in the process. Chemists search for and use new knowledge about chemicals to develop new processes or products. A typical day for someone in this career would include finding medicines to cure diseases, making better functioning hair gels, discovering new processes to solve the worlds energy crisis, and developing synthetic fibers that stops speeding bullets.

My Model of a Vitamix





My first drawing was quite accurate when it came to drawing the Vitamix. But after research (in my second drawing) I could label the different parts correctly and my drawing was a little neater. In my first drawing I also got the dials and switches right on the front part of the Vitamix, while in the second part I also a handle to the Vitamix. In the first drawing I didn't know what the tamper tool was called and after research I found it has three levels and is called the tamper tool. In the first drawing I also didn't realize that the lid had rubber edges the snapped over the outer rim of the Vitamix when put on tightly.

Proving Rock s, Water, and Air are all Matter

__**Rocks are Matter **__

Materials

-rock

-graduated cylinder

-water

-triple beam balance

A rock was put on a triple beam balance and its mass was found, then it was put into 60mL of water to find the volume of the rock. Once the rock was put in the water it rose to 66mL and 66 was subtracted from 60 to get the rock was 6mL (or for solids) 6cm cubed. The rock had a mass of 15.8 grams and a volume of 7 cm cubed.

__**Water is Matter **__

Materials

-graduated cylinder

-water

-triple beam balance

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Water was put in a graduated cylinder at 60mL and placed on a triple beam balance to find its mass, the water was then poured out and the mass of the graduated cylinder was found on the triple beam balance. The two were subtracted from each other to get the mass of water. To find the volume of water it was placed in a graduated cylinder and measured. The water had a mass of 54.6 grams and a volume of 60mL.

__**<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Air is Matter **__

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Materials

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">-balloon

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">-triple beam balance

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">-air

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">A non blown up balloon was measured for its mass on a triple beam balance then the balloon was blown up and measured for its mass again, the two numbers were subtracted to get the mass of air. To get the volume of air cubes were used around the balloon to estimate the volume of the air inside the balloon. The mass of the air was .6 grams and the volume of the air was 1,433mL.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Research of Table Salt and Other Salts <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Table Salt is one of 1,000 salts. A salt is when an acid and a base react to each other. A crystal is a solid that forms by a regular repeated pattern of molecules connecting together. Salt is a compound because it's a substance whose smallest unit is made up of atoms of more than one element bonded together. Table Salt's chemical formula is NaCl. 3 other types of salt other than table salt would include, Sodium Bisulfate, Potassium Dichromate, and Calcium Chloride.



<span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">Separating sand from salt (it's harder than you think)

<span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">First pour the sand salt mixture onto weighing paper and find it's weight using a triple beam balance. Next pour the mixture into a filter that is rubber banded to a beaker. Then pour 100mL of water into the filter and let all the water drain into the beaker below. After that let the water from the sand evaporate. Lastly find the weight of the sand using the triple beam balance and subtract it from the original mixtures weight for the salt's weight.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">The water and sand salt mixture was bubbly when on the hotplate and nothing spilled out of the beaker while on the hot plate. The sand when being weighed scattered a little and was hard to work with. The salt was 2.4 grams and the sand was 3.6 grams out of the 6.0 grams that made up the sand, salt mixture.
