The original design of the rotocopter was straightforward. Flap A and Flap B were to be folded in towards each other, along the dashed line. Rotor A and Rotor B were to be folded in opposite directions. The hypothesis of the experiment was as follows: If the rotocopter is put onto construction paper, it will have more air time. To be ensured that only one variable was tested at a time, the rotocopter was dropped from the same height every time. Not only this, but the rotocopter was checked to make sure nothing was changed each test.

However, the results are completely different. The results shown in the table, the water and cornstarch solution is most suitable liquid to use in the snow globes due to its thick viscosity compared to other solutions. Hence, the marble traveled slower as it created more drag onto the marble. Nevertheless, the water itself had low viscosity compared to other solutions because the marble reached the base faster of the measuring cylinder. As a result, it created less drag onto the marble compared to water and cornstarch solution. Therefore, the thicker the solution, the longer it takes for the marble to reach the base of the measuring cylinder. However, if the solution has low viscosity (such as water itself), the faster it the time it takes for the marble to reach the

This data was tested using a pound of soft, polymer clay, a small Jolly Rancher candy, ruler, pencil, and a measuring tape. The Jolly Rancher weighed 6 grams. The pencil was placed underneath the middle of the ruler for balance. On one end, I placed the Jolly Rancher and dropped the clay on the other end. I started dropping the clay from 107 centimeters. The measuring tape was placed behind the pencil and ruler. I then video-taped the event to pinpoint the exact launch height of the candy. The first experiment had no force

The intent of this experiment is to further practice the scientific method, by constructing a boat made out of aluminum foil to hold as many pennies as possible before sinking in water. I hope to get a better perception of the scientific method by doing an experiment. I also hope to gain knowledge about the way a boat is designed and how it affects the weight that it can support. Based on my research, I know that the smaller the boat is, the less weight it will hold. I also know that if a piece of aluminum foil was laid out flat, it would float. Knowing this I formed my hypothesis. My hypothesis is, if I make a small boat, it will hold about 50 pennies.

To do the first experiment, the work-energy theorem is used. This is based on the equation .5mv^2=.5kx^2, where m is the mass of the duck, v is the velocity of the duck in the air, k is the spring constant of the spring in the base of the duck, and x is the displacement that the spring is compressed. Place a book on top of the .95m table. This will serve as a backstop for launching the duck. Then push the duck so it is compressed and is going to launch horizontally . Do this a few times to find an approximate horizontal distance from the base of the table to where the duck initially contacts the ground. One you have found this distance, focus more carefully on this position so that you can take a measurement from the edge of the table to the position where the duck initially contacted the ground. This allows you to get a more accurate answer. Do this at least five times and take the average. Then you can change the height of by adding a .75m desk on top of the .95m table. Repeat the process of data collection at least 5 times and take the average. Then remove the .75m desk and place it on the ground. The desk will then be used to launch from a vertical displacement of .75m place the duck up against the book and launch it horizontally, again collecting 5 separate data points and taking the average of the

Since the purpose of my experiment was to find out what amount of water made an air-pumped bottle rocket go higher, I had to first learn how to build an air-pumped bottle rocket. After searching on the internet for about 5 minutes I learned how to build one. I spent about 20 minutes building a bottle rocket with a cone and fins.

In this experiment we tested the effect of change in arm length of the Trebuchet on the distance traveled of the projectile. We wanted to do this experiment due to our interests in engineering and our interests in the medieval era siege weaponry. We started by researching different types of Trebuchets and decided to go with the most modular and modern version. We decided to build a floating arm Trebuchet which uses the counterweight as the fulcrum. This allowed us to easily exchange the arms for testing. We built the Trebuchet using long 5.08cm x 10.16cm (2in x 4in) pieces of wood, four 4.54kg (10lb) weights, a single 1.27cm (1/2in) x 1.22m (4ft) piece of rebar, and a pouch made of paracord and duct tap. We tested this by building a Trebuchet

When creating the graphs, x will equal the amount of meters, and y will represent the radius (also in meters). Both x and y will be positive rational numbers, since there can be no negative length and decimals, if available,

This experiment relied on adding mass (by paperclip) to a paper helicopter and dropping at a certain height (2 m).

Experimental Question: How does

The purpose of the lab is to collect data, then from the data determine the potential energy, spring constant, and the maximum velocity of the toy. The toy measured to be 0.055 kg, 0.06 m tall when standing and 0.04 m tall when pressed down. During the experiment, we determined that the average maximum height of the toy is 0.622 m. From this information, we determined, using the equation PE=mgh, that the potential energy of the toy was 0.313 Joules. Then, using the potential energy and the difference between the toy’s height when it's pressed down and when it's freely standing we determined the spring constant by using the equation PE=(1/2)kx^2.

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

The Gauss Rifle experiment ended just as my hypothesis predicted, as I added more stages, the steel ball went farther. I determined this by looking at the distance the balls traveled per stage. I performed 5 trials per stage, my average for one stage was 36.9 inches, my average for 2 stages was 48.3 inches, my average for 3 stages was 54.4 and finally, my average for 4 stages was 60.2. This proves that my hypothesis was correct.

In this lab the researchers were testing how different massed “meteorites” dropped at the same distance affect the depth of an impact crater. The researchers predicted that if the mass of the object in the egg increases than the depth of the impact crater will also increase because gravity will pull down harder on the heavier object than it will the lighter object. The hypothesis was supported because the greater the mass of an object than the deeper the impact crater will be because the greater the mass the more gravity pulls on that object downward.

Overall, I think the experiment went well, but the results collected at the end were invalid and reasonably inaccurate, however, on the other hand, errors and mistakes occurred during the investigation. The dropping time of the parachute was not accurate because it went off course, so it is not reliable as we could not control the factors which affected the parachute. This is because the parachute had more air resistance, but the weight force was less and took way too much time to reach the ground. For example; the weather and weight affected the parachute’s drop time and we could’ve tested the parachute from different heights to get more accurate and valid results.
