=Two Types of Experiments Extension= The purpose of the experiment I performed was to find out which rubber band would break with more distance it is stretched back, the small but strong rubber band or the thin and long rubber band. This experiment was a comparison experiment because we were comparing the bands to see which one would break easier. The control of this experiment was the long rubber band because we thought that because it was longer it would be easier to stretch farther. The independent variable of this experiment was the size of the rubber band. The dependent variable of this experiment was the stretch distance. Our method used to conduct this experiment was to step on the rubber band and then pull it up with a ruler to break it. We would do that numerous times and record the results. The medium sized rubber broke at the farthest distance with 62.5 centimeters. The small sized rubber band broke the least far distance with 27.5 centimeters.

The purpose of the experiment I performed was to find out which paper airplane would fly in the air most time. This experiment was a comparison experiment because I was comparing to see which paper airplane would stay in the air the longest. The control of this experiment was the steamer plane. The independent variable of this experiment was the plane type. The dependent variable of this experiment was the time the airplane is in the air. Out method was to use a timer to time how long the plane was in the air and then repeat that and record. The" glider" flew in the air the longest with 3.31 seconds. The "Doctor invert" flew in the air the second longest with 1.21 seconds and the "Standard Issue" came in last with 1.14 second.


 * ISP Reflection**

On your Student Pages Wiki site, write a paragraph that includes the following:

1. Title - "ISP Reflection"

2. The problem you were trying to solve

3. The answer to the problem

4. How you felt your experiment went

5. How you felt about working on an independent science project

ISP Reflection

For my ISP project I wanted to know whether different magnets would be affected in different changes of temperature. It turned out to be that different temperatures did affect different magnets, it would affect them negatively as well as positively. The experiment went well for the most part but when I was experimenting there were some results that shocked me and I thought I did something wrong, no matter how many trials I did, based on my background research. I feel like working on the science project independently helped me to push forward and learn some new things that I would not learned if someone were to help me. I also feel that if I worked on it with someone else I would have got more background research done and I would have been able to hear out different ideas from mine and I would have most likely learned something new.

ISP Job Reflection

The career choice of physicist would relate to my ISP. The physicist career choice relates to my ISP because physicists conduct many experiments as I did with many trials. Physicists could study magnetism as I did too for my project with testing the strength of magnets with them being affected by changes in temperature. A physicist would study and research the properties matter and energy. A typical day for a physicist would be that they would most likely work in R&D and conduct many experiments. They would also design different types of research equipment.



An Original Model of a Light bulb



There are some differences from the first and second model. The first model shows everything the second model has but the second model has even more and is a bit more descriptive. The second model shows that is has inert gas, support wires, metal contacts and electrical foot contacts. the first model shows a screw thread contact but does not label it and what is inside it (insulation). Also the second model is a bit more descriptive with the filament, because in the first model it just says "filament" but in the second model it says "tungsten filament". The second model looks a lot more realistic than the first one and looks like as if it was cut in half, showing how all the parts work.

Showing That Rock, Water, and Air are Really Matter.

A Rock is Matter

The materials needed for proving that rock is matter are: To prove that a rock is matter there were a couple of steps that were done. First the rock was put on the triple beam balance and the mass was recorded. Then the rock was put into a graduated cylinder filled with 60 milliliters of water and then the height of the water was recorded. Then the difference between the two measurements were recorded.
 * a rock
 * water
 * a triple beam balance
 * a graduated cylinder

It was proven that a rock is matter. A rock is matter because in the experiment the rock had a mass and a volume. The mass of the rock was 25.5 grams. The volume of the rock was 10 cubic centimeters.

Water is Matter

The materials needed to prove that water is matter are: To prove that water is matter there were a couple of steps that were done.First 50 milliliters of water was poured into a graduated cylinder, then the height of the water was recorded. The mass of the graduated cylinder was recorded, then the mass of 50 milliliters of water in the graduated cylinder was recorded. Then the two numbers were recorded.
 * 50 milliliters of water
 * a graduated cylinder
 * a triple beam balance

Air is Matter

The materials needed to prove that air is matter are: To prove that water is matter there were a couple of steps that were done.First measure the mass of just the balloon and the bucket on the triple beam balance which was 147.6 grams, then measure the mass of the balloon inside the bucket and with air inside it which was 147.7 grams. Then the difference between the two numbers was found. To find the volume of the balloon, the diameter was measured and then the equation of 4/3*PI*r^3 was used.
 * balloon
 * triple beam balance
 * air
 * cubic centimeter cubes

Salt is a very interesting element that we find everywhere. Salt's chemical formula is NaCl which means Sodium Chloride. A salt is any of a class of compounds formed by the replacement of one or more hydrogen atoms of an acid with elements or groups. A crystal is a substance having a natural geometrically regular form with symmetrically arranged plane faces. Salt is considered a compound because any compound is formed by two different elements. Some different types of salt are: [|Calcium carbonate], [|Sodium carbonate], [|Sodium acetate], [|Potassium cyanide], and [|Sodium sulfide]. Even though there are many different types of salts salt is a very unique compound.

Sand and Salt Separation Challenge

In this challenge the mass of salt and sand has to be weighed. The method that was used to complete this challenge was very helpful. First the salt and sand mixture was poured into a beaker with water. Then the mixture was poured through a paper filter, and into a beaker. After the sand was captured into the filter the salt water was left by itself. Then the sand was weighed on a triple-beam-balance. After that the salt water was heated to 245 degrees Celsius over the day. After that, then the salt was isolated from the water. Then the salt's weight was measured on a triple-beam-balance also.

There were many interesting results that were found in this experiment. After weighing the sand, we found that its weight was 2.9 grams. After weighing the sand, we found that its weight was 2.6 grams. If the same amount of sand and salt was poured in together, then it can be concluded that the sand and salt weigh about the same amount. It might be off by 0.3 down or up or more than that because of the un-controllable constants.
