=Two Types of Experiments Extension=

// Paper planes Experiment // The purpose of this experiment is to see what type of paper makes the paper airplane fly the furthest. This experiment is a comparison experiment because different things are tested in identical ways and then compared to see if they have different results. The control is the copier paper because when you are making an airplane you usually make it with copier paper therefore the control is copier paper. The independent variable is the type of paper because the independent variable is what I change and I am changing the type of paper. The dependent variable is how far the paper airplane flies because that is what I am measuring. Our method was to make the planes the exact same way but with different types of paper. Then we would have our measuring sticks and our three planes made out of Construction paper, Copier paper, and Lined paper. We count to three and then throw the plane. Once the paper airplane hit the ground we would grab the measuring stick and measure from the place we threw it to the place the plane landed. We would do three trials with each type of paper. The results varied. The average for the construction paper was 296.67 centimeters. The average for the copier paper was 465 centimeters. Last but not least the average for the lined paper was 476 centimeters.

// Rubber Band Experiment // The purpose for this experiment is to see if the length of the rubber band affects long it is in the air. This experiment is a relationship experiment because one aspect of this experiment is constantly changed to see if it affects the measurements made. The control of this experiment is the rubber band being stretched 2 cm because that is what feels the most natural stretch length. The independent variable is the length that the rubber band was stretched because I am changing it. The dependent variable is how long the rubber band is in the air because that is what I am measuring. The method we used was to grab three of the same kind of rubber band. Then we got the ruler and stretched the rubber band to the normal stretch. Then stretch it back to the stretches we tried which is 2 cm, 4 cm, and 8 cm.. We shot the rubber band and at the same time started the timer. We stopped the timer right when the rubber band touched the ground. We did 3 trials for each stretch. The average for 2 cm was 1.31 seconds. The average for 4 cm was 1.46 seconds. The average for 8 cm was 1.22 seconds.

ISP Reflection

The main problem that I was trying to solve was to see which liquids (out of the selected liquids. Which were Gatorade Frost, Diet Snapple, Vitamin Water Zero, Deer Park Water, and Diet Coke) had electrolytes (electrolytes- ions that are either positively charged or negatively charged) and which do not. The answer to the question was that all the liquids that were tested worked. Which were the following liquids (contain electrolytes): Gatorade Frost, Diet Snapple, Vitamin Water Zero, Deer Park Water, and Diet Coke. I think this experiment worked out very well. One of the flaws in this experiment was having the experiment being very quick and having no numerical values therefore impossible to make a graph. The main problem (that I was trying to solve) for the second experiment was to see which materials conduct electricity (out of the selected materials which were: Aluminum, Straw, Wax Paper, Cardboard, Paper Clip, and Rubber Band). The answer to the question was that the following materials work: Aluminum, and Paper Clip. The materials that were not listed did not conduct electricity. This experiment went well too. I also found the same problems as the first experiment. Which were having no numerical values, and having the experiment go to fast. I felt like working on the ISP Project was a good experience. Not only was it very fun it was also a very good learning opportunity. Working on this project showed me a portion of what actual scientist do. I very much enjoy this project.

ISP Job Reflection



Many people have asked me what job might relate to my ISP Project. I said engineer, but now that I think about it an electrician might also relate to my ISP project. An electrician works on all things electrical. Which include circuits and for my ISP Project I had to study a lot about circuits. An electrician might have to go to some ones house and rewire the wires in the house, they might also have to install lights or test the bottom of a swimming pool to make sure that the swimming pool equipment prevents electrocution. Having said that a typical day for an electrician might be going to some ones house to rewire it or to test their swimming pool.

My Model Of A Microwave

My first model of the microwave was very different from my second model. My first model had no way of heating the food or beverage. My second model has the heat light the fans, and vents, and the magnetron tube inside which sends radiation waves inside (to heat up the food or beverage). My first model would have let the heat exit from the inside the new model has metal on the out side to keep the heat inside. Inside the new model is fans and vents. Inside there is also a heat light. You also have an LCD screen to see how many more seconds or minutes you have left (to leave your food or beverage in the microwave).

Proving a Rock, Water, and Air are Matter.

To preform the experiment for the rock you had to have Graduated cylinder, Rock, Triple beam balance, and Water. The method to figuring out the mass was to place the rock on the plate of the triple beam balance and counter balance the masses to find the mass of the rock. We figured out that the mass of the rock was 8 grams. To find the volume of the rock you had to fill the graduated cylinder with water to 50mL and then drop the rock in the graduated cylinder. Then calculate how much the water goes up into the graduated cylinder. We figured out that the volume is 3cm3. Which proves that a rock is matter because you could find a mass and a volume.

In order to find the mass for water, my lab partner and I gathered these materials water, graduated cylinder, and a triple beam balance. The method we came up with (to find the mass) was to Pour 50 mL of water into the graduated cylinder and counter balance the masses to find the mass of the water and the graduated cylinder. Then pour the water out and find the mass of the graduated cylinder and subtract the mass of the graduated cylinder from the mass of the graduated cylinder and the water. We figured out that the mass was 54 grams. The method we came up with to find the volume was to pour 50 mL of water into the graduated cylinder and measure the volume. We figured out that the volume was 50 mL. Which proves that water is matter because you could find a mass and a volume.

To find the mass and volume of air my lab partner and I had to have these materials balloon, air, and a triple beam balance. The method we came up with to find the mass was to use the triple beam balance to measure the mass of the balloon (not blown up). Then blow up the balloon and put it on the triple beam balance. And find the mass. Then subtract the mass of the non-blown up balloon from the mass of the blown up balloon. We found out that the mass is 0.5 grams. The method we have to find the volume was to blow up the balloon and estimate how many cubic centimeters are in (can fit) in the balloon. We estimated 2,000 mL. Which proves that air is matter because you could find a mass and a volume.

Separation Challenge

The method that my lab partner and I used was to find the mass of a 200 mL beaker with a triple beam balance. Then, fill the 200 mL beaker with 200 mL of water. Pour the Table salt sand mixture into the water. Mix it up until the salt is dissolved into the water. Next, pour the beaker with the salt water and sand mixture into another beaker with a filter rubber banded onto it. The salt water will go through the filter and the sand will stay in the filter. You will have 1 beaker with salt water at the bottom and the sand in the filter. Then place the beaker on a hot plate to dry the sand and to evaporate the water from the salt water. Once you take the beaker off the hot plate you will have a beaker of salt on the bottom and dry sand in the filter. Then the triple beam balance was used to find the mass of each subtracting the mass of the beaker, rubber band, and filter alone.

The results of this experiment were the sand being 3 grams and the salt being 2 grams. When the salt water was placed onto the hot plate it did not instantly react, but we boiled the water out of it. Therefore leaving only the salt. We did the same thing with the sand in the filter. We burned the water out of the sand. The salt dissolved in the water when it was stirred for a short period of time. We could improve our experiment by having more time to work the method out better.
