=Two Types of Experiments Extension= We were figuring out if the type of plane affects the flight of the plane. This is a comparison XPT because we were comparing the flight time of three types of planes. The control of the experiment is the arrow plane. We measured how much time the plane was in the air. We first tested the arrow plane then the other two types. We measured the air time with a stopwatch. The ball had the most airtime then the condor and lastly the arrow.

Condor: 2:13, Arrow 1:11 Ball 2.51

With this experiment we were figuring out if the number of band shot affects the average distance the rubber band goes. This is a relationship XPT because there is a relationship between the number of bands shot. (No Trumpeters were harmed during this experiment) The control was three rubber bands and the thing we changed was the number of bands. We measured the distance in cm. One rubber band surprisingly flew the farthest then two rubber bands and lastly three rubber bands.

3 rubber bands: 553. 3 2 rubber bands: 634.5 1 rubber band: 657


 * ISP Reflection**

The problem that I was trying to solve was how much lift would be needed to lift a human and which of the three wing designs would be best. The answer to the problem was that the amount of lift is the human's weight and the plane's weight combined. the best wing design was a completely flat wing. I think the experiment was slow but steady. It yielded some faulty results but was good in the end. I felt really good about working on this project. The talk was really fun and I really liked it. I was hesitant at first over what I would pick but I figured it out.

**ISP Job Reflection**
The job of a pilot relates to my ISP. This job relates to my ISP because the pilot has to learn about the four forces that make flight. They also need to know how wind affects the plane in flight. The pilot has to know about the four forces and how to fly the plane. They need to know how to deal with turbulence. A typical day on the job for a pilot would be to make all the flight checks and fly the daily routes. An air force pilot would go on missions and a private pilot would need to be ready for any flight, whenever the client wants it, even midnight to noon flights.



**My Model**




My initial drawing was less educated than the second. In my second drawing I added circuitry and changed the on switch to part of the handle. I thought that you had to time it yourself but there is an electromagnet that times the heat and length of toasting for you. The spring platform and the heater were both correct in my initial model. When i researched it I was able to add circuitry and remove the on switch.

Proving It's Matter
Rock • DEFINE THE PROBLEM Is a rock matter? • MATERIALS & METHOD 66 ml water 1 Graduated cylinder 1 rock 1 triple beam balance Put the rock on the balance and weigh it Then, put rock in water measure the displacement. The displacement is the volume of the rock. • RESULTS & DISCUSSION The mass f the rock is 12.5g The volume of the rock5.5 cubic cm Water • DEFINE THE PROBLEM Is water matter? • MATERIALS & METHOD 1 Graduated cylinder Triple beam balance Water Weigh the cylinder so that you have the weight of the empty cylinder. Fill the cylinder with water then weigh it again. The weight in grams is the mass and the amount of water in the cylinder is the volume. • RESULTS & DISCUSSION The mass of the water was 88g the volume of the water was 87 cubic cm Air • DEFINE THE PROBLEM Is air matter? • MATERIALS & METHOD 1 balloon 1 triple beam balance 4 cubes First weigh the empty balloon. Then blow it up and weigh that. Subtract the weight of the balloon from the weight of the blown up balloon and that is the mass. To calculate volume put the cubes into a square and estimate how many squares go around the balloon and fit inside of it. • RESULTS & DISCUSSION The air's mass was .5 the volume of the air was estimated to be 1600ml

= Salt = The chemical formula for salt is NaCl. That's 1 sodium atom and 1 chlorine atom. A salt is a compound caused by a reaction between an acid and a base. There are several types of salt including but not limited to: Calcium carbonate, Sodium carbonate, Sodium acetate, Potassium cyanide, Sodium sulfide. Salt is considered a compound because it is made of two elements. A compound is two or more elements bonded together. Crystals are solids that are made up of several molecules.A collection of atoms are repeated over and over in crystals.



The Separation Challenge- Separating Salt and Sand
The task we were assigned was to separate salt and sand. Our teacher, Mr. Himburg gave us a beaker full of salt and sand and told us to separate it. We first mixed them with water and filtered off the salt through a filter and the boiled off the water. Then we weighed the beaker of salt and then the beaker of sand. We then emptied the beakers and weighed them.

Our results were that the salt had a mass of 2.25 grams and the sand had a mass of 1.775 grams. To improve this experiment we could have used the same sand and salt. (the beaker the sand was in broke)
