 * Two Type of XPT Extension **

We conducted an experiment to see how far each type paper could go as a paper airplane. This experiment is a comparison experiment because it has words and numbers as its independent and dependent variable. Our control is the copier paper because that is what we make the airplanes most out of. Our dependent variable is how far the airplane can go in centimeters. The independent variable is the type of paper we used which was copier, construction, and lined. Our method was to throw the airplanes at the same spot and measure how far they went. We would record and then repeat for all 3 trials. The average for the copier is 315cm. The average for the construction paper is for 431cm. The average for the lined paper is 571cm.  We conducted the experiment to see how far the rubber bands would go at certain angles. This is a relationship experiment because it as angles which are numbers and the distance that is in numbers. The control is a rubber band that is shot at o degrees. The independent variable is the angles that we shot the rubber bands at. The dependent variable is how far the rubber bands could go. We got 3 rubber bands and we shot them at different angles making sure that we pulled them back to 16cm and then we let them go. We would measure and record the distance and repeated for all of the angles. The average distance for the o degree angle is 480 cm. The average distance for the 30 degree angle was 623.33 cm. The average distance for the 60 degree angle is 480 cm.

==== My science experiment was about the determination of which ice cube type could melt the faster. My results to the problem was that the apple juice ice cubes had melt the fastest and they took an average of 7:30 minutes. The ice cubes that took the longest time to melt was the saline solution ice cubes with an average of 11 minutes. I felt that this experiment took a little to long for me. I should have made the ice cubes smaller and should have used the black metal plate with an additive to melt the ice cubes. I liked the ISP project a lot. It did not bore me in any way because I got to choose what I wanted to do my project on instead of be given a required experiment. ====

====The job that relates to my ISP topic is a hydrologist. This job relates to my topic because they both work with some form of water. They both also analyze water to predict what will happen or what has happen. Someone that has this career measures how much snow is compacted on the mountain tops so they can predict if it might flood in the spring time. A typical day on the job for a hydrologist is performing research at a variety of outdoor places. They would typically record water depths and measure stream flows. They collect and analyze water samples and research historical data on storms and floods. ====

My model of a French Door Refrigerator
The difference between the two models is that the first one has different handles and was originally thought that there was a drawer in the freezer. The second model is a new version of the french door refrigerator. The second model also has more shelves and is a little bit bigger in size. The first model had a water dispenser and the second model has bot a water and ice dispenser. The second model has a third compartment for meats and cheeses or other deli items. The second model has more room to put things in but the first model has more shelf/drawer to place smaller items in. The freezer has more space in the second model because it is a shelf and not a drawer. Then again the french door fridge never had a drawer in the freezer.

Proving that Rocks, Water, and Air are matter

To find out that rocks are matter we gathered the following: Triple Bean Balance, A Rock, Graduated Cylinder, and we would need Water from the tap. We used the triple bean balance to measure the mass of the rock. Then a graduated cylinder was weighed and was recorded its mass. Water was then poured into the graduated cylinder to the 60 mL mark. The cylinder was then measured with the water in it and was then recorded. The rock was then dropped into the cylinder and the amount of water that had raised was recorded. The number that was raised is how much the rocks volume was. The rock has a mass of 15.8 grams and a volume of 7cu 3.

To find out that water is matter the following was needed: Water, Graduated Cylinder, and a Triple bean balance. We used the triple bean balance to weigh how much the graduated cylinder mass is and then added water to the cylinder until it reached the 60mL mark. We weighed the cylinder with the water and then subtracted the two measurements. The volume of water is 60 mL and the mass of the water is 58.2 mL.

To find out if air is a matter the following was needed: Triple Bean Balance, Balloon, A small cube, and air. We weighed how much the balloon weighed on the triple bean balance with no air. We then took the balloon and blew it up to a reasonable size. The balloon did not stick so we had to rub it on someone's head to create electricity stick. After the balloon stuck we measured how much it weighed and subtracted the two weights numbers. The answer would conclude to the mass of air. To find the volume of the air we estimated how many cubs could fit into the balloon. The volume of the balloon was 1500 and the mass of the balloon is 1.7 grams.

Research of Salt Crystals

Salt crystals chemical formula is NaCl. Table Salt chemical name is sodium chloride. Table salt is a cpoumpound that is made up of ionic bonds. It is made up of compounds that can be formed by replacing one ore more Hydrogen ions with another positive ion. A crystal is a piece of a homogeneous solid substance that has a natural geometrically regular shape. Salts are crystals. Salt is consider a compound because it is made up of two different elements. The two elements are sodium and chloride. Other type of chemically salts are Calcium carbonate, sodium carbonate, sodium acetate, and potassium cyanide.




 * Separating Salt and Sand**

To complete separating the sand and the salt you will need a hot plate, the sand and salt mixture, goggles, cold water, coffee filter, short stirring rod, rubber band, 2-600 mL beaker, 250 mL beaker, and a triple bean balance.

The beaker of 250 mL was filled with 100 mL of water. Pour the salt and sand solution into the beaker with water. The stirring rod will be used to stir for 30seconds. The salt should be dissolved. The other dry 500 mL beaker was then used with the coffee filter on the rim and was curled over the edges and had a rubber band on it to secure it. The salt water solution was then poured into the beaker with the coffee filter. Pour about 25 mL at a time into the coffee filter. Once the beakers were empty, and had no water left wash and dry it out. The filter that had the sand in it was then placed into a 500mL beaker. The beaker was placed onto the hot plate at 100 degrees C. With the water that went through the filter and was placed on a hot plate at 100 degrees C. Wait for 5 minutes or until the water has evaporated. Wait 2 or 3 minutes for the sand to dry on the hot plate. Once the sand has dried, place it onto a weighing sheet. Record how much it weighs. The same process was used for the salt that was in the beaker from the water evaporating was with a new clean sheet.

When we separated the salt and sand mixture we found that the sand weighed 3.4 grams and the salt weighed 2.1 grams. The sand weighed 1.3 grams more that the salt. When we observed the mixture before we had started it was a really light brown or a tan color. The beaker with the salt and the sand was 19 grams. The salt and sand weighed together was 5.5 grams. During the process of separating the salt and the sand the salt had turned from a solid to a liquid when it was placed into the water. When the salt dried it was a solid but was not in a crystal form. It was white, flatten and had bubbles. The sand stayed the same throughout the process except when it was placed with the water it had turned a darker shade a brown. To make this experiment better, their should be a larger amount of salt and sand.
