Question/Purpose : The purpose of this lab was to learn how construct and analyze graphs by figuring out the speed of the buggy car. The question was simple: did the buggy car maintain a constant speed throughout its movement. We will be changing the distance the car has to move and will be recording how long the car takes to move that distance. Therefore, distance is the independent variable while the time would be the dependant variable. Procedure : We decided to answer the question by having the car move certain distances and see if the velocity changed. Our setup was on a lab workshop counter. We taped together a 200cm paper ruler that we would then tape down on the counter to maintain a control. We had a designated human timer who would
* In case you are curious, the engine rpm got up to about 7000 rpm and the track speed got up to about 60 mph or more during this clip. I supported the track with a stand and ran the throttle while an observer ran the camera.
After completing the matching portion, the students will then answer four questions. The first question will ask the students to write down any similarities they notice in the graphs. Next, they will answer what differences they notice in the graphs. Thirdly, they will describe how they labeled the independent and dependent quantities in each graph. Lastly, they will analyze each graph from left to right and describe any graphical characteristics they notice.
Our project required our car to go at least 3 meters. Our initial trials were successful because our car went 7,8, and then 9 meters. The car went 7 meters in 8 seconds with a speed of 0.875 m/s. It went 8 meters in 10 seconds with a speed of 0.8 m/s. It finally went 9 meters in 12
The purpose of this lab was to discover how diverse the parking lot at Bunker Hill High School could be, by finding out the Shannon Wiener biodiversity index of the parking lot. The parking lot was used because it does not have much immigration and emigration of the cars. Using an actual ecosystem in the wild would be hard to control, what is immigrating and emigrating out of the experiment. The experiment shows how diverse the cars were, and this can show how diverse an actual ecosystem was during that time of the experiment. This then tells that diversity does matters because if everyone had the same kind of car, then no one would be different. However, if the students, faculty, and guests had a variety of cars in the parking lot, which made the experiment more diverse in the parking lot or the community of cars.
the length of the slope can be used to calculate the speed of the car
Independent Variable The temperatures are going to differ; this experiment is going to be split up for the various temperatures, therefore each boiling tube has water with different temperatures. In addition, a water bath is going to be used to get a high temperature. Dependent Variable Measuring the time, it takes to dissolve the sugar in the water, in minutes. Experiment 2: Investigating the rate of dissolving with different sizes of sugar particles: Control Variable: 1.
Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. The molars range from 1-3.
Back then in the 1960s the ford mustang was a muscle car in the middle age where it started getting recognized for being one of the fast cars on the list while Chevy had to come up with a quick idea to compete with the “ford mustang” after everything Chevy introduced its intense rival the Chevy Camaro. Today is a society we live in now that our generation gets to choose their own opinion between the ford mustang and the Chevy Camaro with abilities such as running in tremendous types of speed occurring in the highway racing, they are more than just cars also they may relate or be apart from each other making it a unique example of muscle cars.
Dependent Variable: The amount of time it takes for the ice cubes to completely melt.
In this chart (3), we can see that "the change of time spending on the
Dependent Variable ------------------ Rate at which the bubbles of oxygen rise, which will be calculated by observing how many bubbles of oxygen rise to the surface of a measuring cylinder (by means of downward displacement) in one minute. This will be measured in bubbles per ten seconds. Control variables: ¨ Volume of substrate used: 100ml ¨ Temperature: taken place at room temperature 21 degrees centigrade ¨ Type of substrate used: Hydrogen peroxide ¨ Mass of meat used: 5g ¨ Amount of water in the test tube in which the oxygen bubbles downward displaces in the water. This is so the time taken for each individual bubble to effectively rise to the bottom of the test tube will take the same amount of time.
Human transportation has always had an impact on the environment, with cars having arguably the largest impact. According to Superfreakonomics by Steven Levitt and Stephen Dubner transportation immediately prior to the development of cars was entirely depended on horses and horse-drawn carriages. By the end of the 19th century, New York had around two-hundred-thousand horses roaming the streets. Each horse created around thirty-five pounds of feces per day. The introduction of cars was expected to provide a much cleaner solution to transportation; however, this was a misconception. In reality, according to Brandon Keim, writer for Nautilis, the late 19th and early 20th centuries were actually the age of street cars. These street cars were
Cars are large objects of great mass which can reach very fast velocities, this can be a dangerous combination if the physics aren’t correct. Seeing as there is over 1.2 billion cars world wide, physicians have put much detail into aspects of cars to make them as safe as possible. In the paragraphs below I will be be briefly discussing different aspects of the everyday automobile and its safety.
Independent variables: The temperature of hcl gas will be decreased and increased throughout the experiment.
Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
