Paper Airplane
====The purpose of this experiment was to find out what type (or shape) of paper airplane flies the longest (sec.). Our three types of paper airplanes were The Bullet, The Arrow, and The Stealth Wing Our control was the Arrow because its the most commonly used plane out of all three. The independent variable was the type of plane we used and the dependent variable was how long the plane was in the air. We did three tries for each plane and then we found the average. I did this experiment with Sahil. I think this experiment was very fun and educational.====

Rubber Band
====The purpose of this experiment was to find out what color (or type) of rubber band flies the farthest (cm.). Our three rubber bands were the brown one, the light brown one, and the white one. Our control was the distance the rubber band was stretched because it stays the same. Our independent variable was the different colors of rubber bands and our dependent variable was the distance (cm.) of how far it flies. Like the paper airplane experiment, we did three tries for each and then found the average. I also did this experiment with Sahil and it was very fun and educational, too.====

**ISP Reflection**
In my experiment, I determined what food conducts the most electricity. I tested it out with 5 foods, Potatoes, Apples, Bananas, Limes, and Oranges. In the end, the lime and the apple conducted the same voltage of electricity. Then came the orange, then the potato and the food with the least voltage was the banana. I think my experiment went well but there could have been some improvements. The food was not very fresh, and some foods rotten before others and that can effect the voltage they conduct. I could of also tried to do an extended experiment. I liked the ISP, but I think it could have been better by having more than one person in one group. If someone is not really talented in something, the other people in their group can do that part.


 * ISP Job Reflection**

If my ISP project would be tested for a profession, that profession would be a Food Scientist or Technologist. This career relates with my ISP project because food conducts better electricity if they have many electrolytes, more electrolytes in food could be more or less healthy, or taste better or worse. A Food Scientist of Technologist would research and experiment so that they can try and make fo od  taste better, healthier, etc. A typical day in the life of a Food Scientist or Technologist would be experimenting over and over and over with different food materials to get a different flavor, texture, color, nutritional content, or adherence.

==== ==== **Model of a Lightbulb** ==== ====

I was right about the filament and the electrical wires, but what I didn't know about a lightbulb is that there are 4 wires, 2 support wires and 2 electrical wires. I also thought that there was oxygen inside the bulb but there is actually inert gas.

==== ==== The purpose of this experiment was to find out if a rock is matter. A Triple Beam Balance, Water, a Rock, and a Graduated Cylinder where used for this experiment. A rock was dropped into a graduated cylinder filled with water. The water raised and the data was recorded. To find the mass, the rock was placed on a triple beam balance. The mass of the rock was 10.9 g and the volume was 4 cm³

The purpose of this experiment was to find out if water is matter. A Triple Beam Balance, Water, and a Graduated Cylinder where used for this experiment. In this experiment, water was poured into a graduated cylinder. The data was recorded. The graduated cylinder filled with water was placed on the triple beam balance. The graduated cylinder was placed on the triple beam balance and the result was subtracted from the previous one. The mass of the water was 97.5 g and the volume was 100 ml.

The purpose of this experiment was to find out if air is matter. A Triple Beam Balance, a balloon, and air where used for this experiment. Air was blown into a balloon. The circumference of the balloon was measured and the volume was calculated. The data was recorded. Then, the mass of the balloon with air was subtracted from the mass of the balloon. The mass of the air was 1.7 g and the volume was 10,569 cm³.

=**Table Salt**= ==== ==== Table salt is made up of Sodium Chloride (NaCl). A salt is an ionic compound reaction between an acid and a base. A crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an ====<span style="font-size: 1.066em; font-weight: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;"> ==== ordered pattern extending in all three spatial dimensions. Salt is considered a compound because it is a combination of 2 elements. Some other types of salt are Calcium carbonate, Sodium carbonate, Sodium acetate, Potassium cyanide, Sodium sulfide


 * Separating Salt from Sand**

<span style="font-family: Arial,Helvetica,sans-serif;">Pour the mixture of salt and sand into a beaker with 200ml of water. Use the stirring rod to stir the water so the salt dissolves in the water. Put a coffee filter on a 600ml beaker with a rubber band and pour the water in the beaker. Next, put the water in the 600ml beaker in a hot plate that is 405 C. Let the water evaporate so you are left with salt. Weigh the salt in a triple beam balance. Weigh the beaker and subtract it from the weight of the salt. Turn the coffee filter with the sand inside out and put it in a beaker until all the sand is in the beaker. Evaporate the water with the sand. Weigh the weighing paper in the triple beam balance. Put the salt in the beaker on weighing paper. Put the weighing paper on the triple beam balance. Subtract the weight of the weighing paper from the sand and the weighing paper.

<span style="font-family: Arial,Helvetica,sans-serif;">The weight of the sand was 3.1 g and the weight of the salt was 1.9 g. The total mass of the mixture of salt and sand was 5 g.
