For my science fair project, I have decided to answer the following question: “How heavy is a bubble?” I chose this project because it deals with physics, a type of science that I enjoy, and because I love making bubbles. When doing this project, I have to find how the size of a bubble relates to how fast it falls. In order to do this project, I must make something to create the bubbles, then record how long it takes each one to fall. The rest of this paper will show the research I have put into my science fair project. It will also explain how I will eventually answer my main question: “How heavy is a bubble?” In this research paper, I plan to share the information that I’ve found about my project. I will start out with a description of the …show more content…
The experiments within my project should be able to fully answer my research plan questions. The first question to be answered is, “How is the size of a bubble related to how fast it falls?” Without air resistance, mass does not affect the speed at which something falls. Air resistance is the force that will be going against the bubbles falling. In the experiment, there will be multiple different sizes of bubbles including the presence of air resistance. Velocity depends on acceleration, time, and initial velocity, not mass. This leads to the next question to be answered. “How much does air weigh?” If air has mass, then that means it also has weight. However, the pressure of air depends on where you are on Earth, so it is difficult to determine exactly how much the air weighs in an area. Force and surface area are important parts of pressure, and go along with the experiments in my project. Gravity will also play a role in how each bubble falls. The next question is, “How long does it take for a bubble to fall?” This question depends on the other questions. In each experiment, I will record how long it takes for each bubble to fall with a stopwatch. Part of the experiment is seeing how fast each size falls. Finding out how fast they fall will help answer how heavy a bubble is; the final
List how you are going to implement each solution. How are you going to make your solution work?
I am doing this experiment to find the density of aluminum foil to see if it floats or sinks when placed in water. I hope to find how the density of aluminum foil changes when weight is added to the foil. I hypothesize that the boat will hold 20 pennies before sinking.
Thorough analysis of the graph displayed enough evidence suggesting that an increase in substrate concentration will increase the height of bubbles until it reaches the optimum amount of substrate concentration, resulting in a plateau in the graphs (figure 2). Hence; supported the hypothesis.
Ever wonder if the weight of a Frisbee affects how far you can throw it? I have. This experiment is designed to figure out if a heavier Frisbee goes farther or closer than a lighter Frisbee.
5. In light of this experiment, can you offer any advice to children in how to create a device that will keep an egg from breaking when thrown off of their school’s
Bubble gum made the Guinness Book of World Records, with the largest bubble ever made measuring 22 inches in diameter. The greater the molecular weight of the gum, the stronger is the film, and the larger the bubble that can be blown. On the other hand, increasing the molecular weight or size also tends to make the gum more difficult to chew. A technical breakthrough in 1999 allowed manufacturers to create uniquely textured bubble gum by using soft candy or toffee manufacturing equipment. The resulting bubble gum is similar to chewy candy, but lacking the stickiness.
The science project I am going to conduct contains me trying to find which amount of surface area of an Alka-Seltzer tablet gives off the most gas bubbles once I drop the tablet into water. The Alka-Seltzer tablets will be crushed into different equal surface areas ranging from crushed to cut in halves or in quarters. After that I will then add the Alka-Seltzer tablets inside of the balloon.(¨Bubbles, Gas, and Balloons¨) I am going to measure the amount of gas bubbles the Alka-Seltzer tablet gives off by attaching a balloon to the top of my Erlenmeyer flask and then measure the circumference.
Obtain two decalcified eggs, provided by your teacher. Gently blot them on a paper towel and determine the mass of each, using correct procedure (use weighting paper or a container on the balance). Record the initial mass of each egg in the spaces provided in Data Tables 1 and 2.
From the data table, we found that the more paper clips the faster it will fall taking average 2.10 seconds to reach the ground for the class when the whirligig had 4 paper clips on it. However, when the whirligig had only one paper clips it took an average of 2.4 seconds to fall to the ground for the class. This happened because the more something weighs, the greater relationship it has with gravity. The more weight something has the less air resistance can pull up on it and counter gravity but when less are used less gravity is pulling down on it making it float more. Which why fewer paper clips used on the whirligig the more time it takes to fall to the
My experiment was if an egg was changed by cooking or freezing it will it affect how far it would fly. So I did the tests and my hypothesis was wrong. The frozen egg did not fly the furthest, the raw egg did. The raw egg every time went about 1-2 feet more than the frozen egg did. I think this is because when I froze the egg it gained weight and the raw egg stayed the same. This was enough to make the frozen egg not go as far. In fact the frozen egg flew the least amount of distance except for on the first launch where it came in second. This Experiment change but modified to be more exact by moving it into an indoor facility. This will help with not having to deal with wind or any other weather conditions.
As the boomerang spins, the airfoils at its perimeter create lift. Our text, Physics: A World View, discusses aerodynamics and Bernoulli’s principle. It explains the relationship between the velocity of a fluid and the pressure that the fluid exerts. A fluid gains energy when it speeds up as, for example when it goes through a constricting area in a pipe or passes around an airfoil. Since the gravitational potential energy is constant, the change is in kinetic energy. Since there is an acceleration of the fluid, the press...
