The activity we took part in during class encompasses elements which define science: studying, observing, and experimenting. The "Newton Cars" activity tested Newton's second law motion: force equals mass times acceleration. In my group (group 1) we used our knowledge of Newton's second law of motion to form a inquiry to test: what will happen if weight is added or taken away from the car? Using the equation f=ma we determined the which objects in the experiment symbolized each part of the equation. We experimented by changing the variables (weight and number of straws) which allowed us to observe Newton's second law in action. Through our experiment and observation, we answered our initial question and proposed several more during the activity. We raised questions and answered them through actively researching and observing an experiment, all of which outline "science".
The Newton Car experiment that we worked on last Tuesday applies to multiple aspects of science. First, we developed questions and ideas at the beginning of the experiment. In addition, our developed questions help us look at certain scientific points of the experiment. One of our questions included: How does the experiment apply to Newton’s laws? The next aspect of science was experimenting the activity. During the Newton car experiment, we changed two variables in the experiment, one variable was the amount of pennies in the bottle and the other variable was the amount of rubber bands used to slingshot the bottle. After our observations, we come to realize that the Newton Car experiment applies to the third law. Newton’s Third Law states the following: when there is an action, there is an opposite equal reaction. When the rubber bands slingshot the bottle, the Newton Car pushes backwards as the Newton Car lies on top of the straws. The Newton Car goes backwards because the force that shoots the bottle forward, which makes an opposite equal reaction that pushes the car backwards. In addition, the car is able to move backwards because the straws represent the frictionless surface. The Newton Car experiment applies to science because it relates to Newton’s Third Law of Motion.
I consider what we did on Tuesday to be science because of our adherence to the scientific method. We asked questions (i.e. What would happen if we took the pennies out of the cup before catapulting it? What if we took the straws away?). As a departure from the method, we relied on conventional wisdom as opposed to research to make our hypothesis (i.e. heavier objects, when catapulted, are likely to move over a shorter distance than lighter objects on which the same force is applied). The aforementioned example was one of our hypotheses, as was the idea that more rubber bands would catapult the cup further along. We then tested these hypotheses and others, analyzed our data to determine whether or not our hypotheses were valid, and recorded our conclusions.
The Newton Car experiment would definitely be considered science. I see this for many reasons, including the fact that we were (maybe even inadvertently) in compliance with the scientific method process the entire duration of our experiment. Of course, this alone does constitute our experience as “science” as many things in the non-scientific categories of life tend to follow a scientific method of sorts by making a hypothesis, testing that hypothesis, and then drawing some kind of conclusion based on that testing. However, in addition to following this method in our experimentation, the experiment itself proved to be scientific as it dealt with the components of force in regards to mass and acceleration. The majority of our questions before beginning the experiment involved the different components of the experiment like the string or the straws; I specifically asked why we needed to use fire. The thoughts behind the questions were: “How is this going to be useful and what would happen if we just took this away?” The significance of these questions is that those elements of the experiment are what established the relationship between force, mass, and acceleration which ultimately constitute the work as science in correspondence with Newton’s laws of motion.
I feel the "newton's car" activity we all participated in Tuesday night during class was most definitely science. In performing the experiment our class followed the scientific method. We began the experiment by asking questions and forming hypotheses based on what we thought would happen during the experiment. We then changed variables to test our hypotheses and recorded our results. The variables that we manipulated ranged from the amount of pennies used as weight, how many rubber bands were used on the car, and even how far apart the straws were that the car would roll on. All of these changing variables allowed our group to observe how the car's motion was affected. This experiment helped us to visualized Newton's second law of motion, which states that, for every action there is an equal and opposite reaction. The force of the bands throwing the pill bottle backwards also pushed the rest of the car forward.
The Rocket Activity: Newton's Car was most definitely science. The object of the experiment was to investigate the relationship between mass, force, and acceleration as shown through Newton's second law of motion. In order to do this we had to incorporate the scientific method which is used to investigate new phenomena and obtain new knowledge. The very first step in the scientific method is to "define a question" which is exactly what we do. Our groups question was "what will happen when more weight is added to the medicine bottle? What about when that weight is taken away? And how will the amount and position of the straws affect the experiment?". We observed what was happening by testing our question and forming a hypothesis. Along with performing the scientific method we investigated Newton's second law which basically states that Force = mass x acceleration. Once the string was burnt and the car projected backwards, the distance of how far the car moved demonstrates Newton's second law. The distance that the car travels depends on the mass of the medicine bottle and how fast the car is able to roll across the straws. The greater the mass of the medicine bottle the father the car moved. Through using the scientific method to come about our results and determining that there is a relationship between force, mass, and acceleration we know that the experiment done on Tuesday was indeed "science."
The experiment we conducted together in class could most definitely be considered science. We tested the correlation between force, mass, and acceleration, and found that our outcomes were in line with the Newton's Second Law of Motion. Science itself is the study of the structure, function, and purpose of things work. All of this study is through experimenting, observing and analyzing. To conduct the experiment we had to stay true to the scientific method as well. For the experiment we had to test different variable of mass to see how it would affect the acceleration of the car. We made a hypothesis of how the car would move based on past knowledge of Newton’s laws and tested to see if our findings aligned with Newton.
The newton car experiment we participated in was certainly science. It was science because it involved all steps of the scientific method. We asked a question, constructed a hypothesis based on this question, tested our hypothesis by conducting an experiment, analyzed our data, drew a conclusion and communicated the results. We were able to take the scientific method and discover first-hand Newton's second law of motion. This law shows how force, mass and acceleration are all dependent upon each other. We were able to see a visual demonstration of this in our experiment. Mass was represented by the number of pennies we used, acceleration was determined by the amount of rubber band used. Both the acceleration and mass together determined the force or distance the car moved. Discovering this through asking questions, forming hypothesis, analyzing data and experimenting is most certainly science.
On Tuesday, we conducted the Newton Car experiment, a science project. I consider this experiment to be science because of we used the scientific method to come to the outcome. In our groups, we read over the instructions, gathered our materials, and brainstormed. We needed to figure out how we were suppose to construct the Newton Car. We brainstormed questions that came to mind before we performed the experiment in hopes that our questions would be answered. THen, we began our experiment, recording all of our data. We were able to come to a conclusion from following the scientific method. Our group noted that the amount of pennies in the medicine bottle (mass) determined how far the medicine bottle launched forward and the Newton Car back (force). Changing our experiment from just one rubber band to two determined the acceleration.
What we did on Tuesday was definitely science. Not only were we dealing with physics and Newton’s laws, we were dealing with gravity, mass, and experimentation. With any good science experiment we had to use the scientific method to determine if our hypothesis would work. We had to test our theories several times for accuracy in order to draw some conclusion. Even though we did not exactly calculate aspects like gravity and acceleration, we understood the concepts behind it. We understood that mass effected distance. We also understood that fiction plays a part in stopping both our objects that were in motion. From pervious experience we knew that an object in motion would stay in motion unless another object intervened. In this cause that object was the fiction from the ground. This is why the straws where necessary; they helped to keep an object in motion.
On Tuesday the experiment we conducted can easily be defined as science. We used many elements of this including but not limited to: the scientific method and Newton’s laws of motion. In the very first step of conducting our experiment we came up with hypotheses about what would happen when we burned the string. We then manipulated different variables in order to test our hypothesis. After we conducted each experiment we formed a conclusion based on our observations. In conducting our experiment we realized we were applying Newton’s second law of motion, force equals mass times acceleration. The straws were providing force for the car to move forward or backwards. The mass was the weight of the canister, which we manipulated by adding or taking away pennies. The acceleration was the ending measurement of how far the car moved. By using different elements I can confidently say that the experiment conducted on Tuesday night was most definitely science.
The experiment we completed in class was much so science because of several different reasons: 1. We were able to use the scientific method when completing the experiment. We came up with several questions and hypotheses that could be tested by changing different variables (number of pennies, straws, and rubber bands). 2. While doing this experiment we were able relate to Newton’s three laws of motion and observe that his theories were realistic. We were able to record the variables that caused the car to move a certain distance, the amount of force that was exerted, and what factors may have manipulated the Newton car experience: Newton’s first law of motion: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. While we set up our experiment we were able to see that no force was applied to make the car move before we unlighted the string. Newton’s second law of motion: Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector. After lighting the string we were able to see that breaking the string and causing the rubber bands to react as a sling jot caused the weight of the pennies to release the object in a straight direction (due to the placement of the straws). Newton's Third Law of Motion: For every action there is an equal and opposite reaction. We observed the movement of the Newton car was released in such a manner based on the amount of weight and force. The fewer the pennies and rubber bands we used, the less force was reacted upon the car.

ReplyDeleteHow are you concluding that Newton's 2nd law was tested? What F, m, and a did you observe?
