EXPERIMENT 1: MEASUREMENT AND ERRORS INTRODUCTION Observations for physics experiment can be made qualitatively and quantitatively. Qualitative observation is typically descriptive figures and the information is not in mathematical form. While, quantitative observation is based on mathematical figure. Due to that, qualitative observation is imprecise and harder to analyze than quantitative data. Physics is the study, where mathematical equations can be use to express the fundamental laws of nature. Consequently, it is possible to make precise, quantitative evaluation between the observations during experiments and the predictions of theory. Certain basic quantities must be measured in order to evaluate quantitatively the laws of physics
What do you call an alligator in a vest? An investigator! How do turtles talk to each other? By using shell phones! Why are teddy bears never hungry?
In conclusion, the characteristics of the scientific method are far from few. Most distinctly, science deals with the uncertainty of the unknown, attempting to make it known. Though complicated, Barry explains his beliefs on the scientific method with strong diction to show the formality of science, rhetorical questions to show the uncertainty, and logos to show the intellect of science. His rhetorical strategies help the audience understand the plethora of characteristics in the realm of
The three different research methods are naturalistic observations, surveys, and case studies. A naturalistic observation is when someone is observing people or animals in a natural environment or set. A naturalistic observation would be good to use when you observing people in a a cafeteria. For example under appropriate conditions, you can observe the amount of people who naturally order healthy food verses unhealthy food. Naturalistic observation are good only if you take the time to observe people in their natural environments.
However, to quantify information means not only involving numbers or

Several weeks ago, there was a national conversation about sexual harassment and assault with the #notokay moment. I spent some time reflecting on the experiences I 'd had in high school, college and as a young woman. My oldest daughter, who is in seventh grade, and I spoke about my experiences. I wanted her to know that she doesn 't need to accept being treated as prey and that she would be doing these boys a favor by informing a teacher or administrator if a boy touches her or makes lewd comments or otherwise harasses her. My thought was that some of these boys may have a man as a role model who is setting a poor example when it comes to respecting the dignity of others, and that early education/intervention could help the boys.
1.1 Explain how observations are used: Reference- www.slideshare.net. Text book- Penny Tassoni. Laser learning.
Measurements, Calculations, and Significant Figures Measurements, calculations, and significant figures are vital mathematical terms used to understand the basic concepts of physics. Knowing how to properly make measurements and apply the necessary calculations to obtain accurate answers will surely prove beneficial in physics, but having that knowledge will also help you throughout your entire life. Therefore, it is important to understand the processes and numbers involved when using measurements, calculations, and significant figures. Measurements are used to identify the specific characteristics of an object, such as length, size, and amount. One must use the proper measuring device, depending on the conditions of the experiment and
Thus the measurements will repeat for each experiment, where the paper cup’s height from the ground varies in each
This experiment has to be carried out carefully
In mathematics the knowledge we obtain is justified with reason that have straightforward theories and laws. In natural science on the other hand the information we collect is firstly obtained with observations which can be perceived in the wrong manner and then carried out wrong after that, in the natural world things are always changing therefore the results we get now won’t necessarily be correct one hundred years down the line therefore the knowledge we have now of the natural sciences is correct until proven wrong. Knowledge is trustworthy in most of our subjects at school but we can never know if the information we are receiving is 100% accurate or not because in the future we may learn that the information we have is
Student Engagement A good teacher should know how to engage students in learning activities and be able to respond to diverse students needs in the classroom. The classroom observations I have seen these past week has shown me examples of good teachers. In all the classes I observed the students sat quietly and were always ready to raise their hands and answer questions. In my kindergarten class all the students were really into their assignments and wanted approval of their work from their teacher.
In quantitative research, variables are identified and defined, and then relevant data is collected from study participants. A strength of this type of research is that the data is in numeric form, making it easier to interpret. It also studies the relationship between independent and dependent variables and can address questions such as does a relationship between variables exist, what is the direction of the relationship, how strong is the relationship between the variables, and what is the nature of the relationship. To be able to discover and answer the cause-and-effect relationship is a strength of quantitative research. Lastly, in quantitative research, the study can either be experimental or nonexperimental, meaning clinical trial or observational study, allowing for different types of research studies to be conducted.
