In the Balloon Car experiment, we made a toy car that was powered by a balloon. We filled a balloon with thirty pumps of air, and attached it on the car in a way so that the only way the air could be released is through a straw. We acquired three different types of straws that each had different sized holes, and observed the changes in speed that happened because of the difference in diameters. We recorded the data by measuring distances on the floor to make a track, and ran the cars along the track while timing how long it took. We found the average time the car with each type of straw took to go the distances of 25 centimeters, 50 centimeters, and 75 centimeters. In the experiment, the straw with the largest diameter made the car go the fastest, while the straw with the smallest diameter made the car go the slowest. Also, the car always sped up towards the end of the track, no matter what the size of the straw was. From the data, we learned that if an object can reach a faster speed quickly, it will go faster than an object with a constant acceleration. The Balloon Car experiment was meant to observe how the speed of an object would change if the object’s rate of acceleration changed. In the lab, we made a balloon powered toy car, and changed its acceleration rate by changing the diameter of the straw that was …show more content…
We solved the first problem by pumping both balloons up thirty times with a pump. We solved the second problem by making sure the straw was attached in the middle of the car, and was straight. If I had to do this experiment again, I would have used wood for the base of the car, not styrofoam. Styrofoam was not sturdy enough, and it was hard to attach some things like the wheels to it. I learned many things while doing this project, and would recommend it to
According to Miller, Ron. The History of Rockets. N.p.: Grolier, 1999. Print. "The forces of action and reaction, which propel the rocket forward, occur the moment the fuel is burned-before the exhaust leaves the engine." (Miller 10). the combustion within the motor is burning the fuel (reactants) causing the exhaust (products) to leave the motor pushing the rocket up.
The purpose of this lab is to see if changing the temperature and the surface area affects the speed of the solute dissolving. This lab relate to the things you have been learning in class because it connects to solubility and how the change in temperature, surface area, and concentration affects the rate in which a substance dissolves. In this lab we hypothesize if we increase the temperature of the vinegar, then the speed of the Alka-Seltzer would increase as well because the speed of the molecules breaking down will be faster. If we also increased the surface area of the Alka-seltzer, it will also dissolve quickly because the pieces are little. In order to complete the surface area experiment, we put our safety goggles on to prevent any
Combustion reactions consist of three main things that are put together to depict something called a combustion triangle: heat, fuel and oxygen, in the experiment we conducted we used the matches that were provided in the lab, for the fuel we used Acetylene (C₂H₂) and the third component is Oxygen gas (O₂). Moreover such reactions must be conducted under great care because of the combustions that occurs, therefore any person interacting with such reactions should be completely aware of the dangers that accompany such experiments
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
Drag: Here's where aerodynamics come into play. As an object moves through the air, it is met with air resistance as speeds increase. This air resistance pushes against your CO2 car and prevents it from going as fast as it could in a vacuum. You can't completely ever reduce drag, but you can help reduce it by building a more aerodynamic car, but those are more difficult to create.
For example, I started off with a plastic water bottle but, I could not get it to be proportionate. I ended up changing my car structure to a piece of cardboard because it was proportional and light. I also changed from three small narrow straws to one big straw to blow up the balloon. In addition, I used tape instead of hot glue because the hot glue was too heavy for my car and the hot glue strings kept going under my car which made it have lumps in the tires. I also tried a bigger balloon but, the balloon did not have a good impact so the air would come out very slow instead of
The main problem being investigated in this experiment is the different rates the color on a skittle dissolves when sugar is added to water. The experiment was to determine which amounts of sugar would affect the rate at which the color on a skittle dissolves. According to Little Bins for Little Hands, skittles are supposed to be able to dissolve in water (Littlebins, 2016). I did not know water could help the skittles dissolve faster, and I thought the sugar I added would help them dissolve at a faster rate. This experiment really caught my eye because I was personally really intrigued as to how the amount of sugar would affect how fast the color on a skittle would dissolve. I’ve never heard of anyone doing this experiment so I wanted to test it for myself to see what kind of results I would get. Whenever the skittle was dropped into the water it would sizzle, and the process of dissolving would occur. My hypothesis was “If the amount of sugar is increased, then the rate it takes for the color on a skittle to dissolve will decrease.” The experiment was all around very fun, however the results I collected were not what I was anticipating.
When we were designing what our machine was going to be like, we wanted it to be simple, yet have at least 10 steps and 6 forces. With our design, it will have 12 steps and 6 forces. I am actually really proud of our design. It comes out to be relatively simple, but it gets the job done. Starting with step 1, there is a fan that one of my group members starts by pressing the button on the fan. The fan blows air to get the paper to fly forward away from a toy car that it parked at the top of the race car track ramp. The paper flies forward because of lift force. Next is step 2. The paper rubs against the back of the toy car as it gets blown away. Then, this make the car start rolling. This is contact force. After that comes step 3. The car now

So that’s why people dragster. For the history the exhilaration. The power. The excitement. And the things you can learn while doing it. Same thing applies to co2 cars too. The science and math and other things are the things you can learn too by doing this project with aerodynamics and the specific things you need to propel an actual dragster car. Just fascinating. The reasons are what you already know (I know I think too deep into that). But overall it’s just fun to ride make and do altogether. Fun for all ages. So that’s why. Why people

The aerodynamic efficiency is the single most important element in designing a competitive car for professional racing or getting the car model on the front of a Car and Driver or Motortrend. Aerodynamics is the study of the motion of gases on objects and the forces created by this motion. The Bernoulli effect is one of the most important behind car design. The Bernoulli Effect states that the pressure of a fluid, in gaseous or liquid state, varies inversely with speed or velocity and a slower moving fluid will exert more pressure on and object than the same fluid moving slower (Yager). The goal of car designers is to make the air passing under a car move faster than the air passing over the car. This causes the air passing over the car to create more downforce than the air passing under the car creates upforce creating a force additional to the car’s weight pushing the car to the road. Large amounts of downforce are needed to keep light cars grounded at high speed and keep to cars from sliding around turns at high speeds.
Is it ethical or even helpful to try to impose order on a haphazard existence? Is it right to play God, to steal the limelight from the cosmos? Man used to ponder existence, but with the increasing possibilities of science, we now ponder our power over existence. In “An Experiment with an Air Pump,” Shelagh Stephenson uses symbolism associated with Isobel as a voice of foreboding in a society “enraptured by the possibilities of science” (3). Stephenson associates Isobel with a bird, a pile of bones, and a sheep to reveal the dark side of the “light,” the scientific revolution.

Hobby is an activity that people like to do when they are free. This hobby is advisable for those folks who have a passion on creating handmade stuffs, at the same time, they are interested in the variety models of the cars. Despite craftsmanship is necessary, designing also can be unrolled through this according to the inspiration of that person which would come out anytime. The challengeable and interesting hobby is building the electric toy car. The car should be completed by fabricating it with their hands where some crucial processes should be carried out. A complete circuit is involved in the whole model which generates current to the toy car and causes it to move.
