Sarah's STP Thoughts and Reflections

 When conducting experiments, there are various ways in which you can record and present data, depending on the audience and the overall message behind the experiment itself. When presenting data, the standard that many choose to follow is to publish relevant data on a graph. Usually, graphs are used to display relationships between variables.  Graphs can be displayed in many ways, but they generally take the form of a linear model, a proportional model, and/or an inverse proportional model . A linear model is displayed on a scatter plot and the line of best fit for all of the data points is generated to create a straight line that displays the average line according to the data. This line, as was aforementioned, is the average of the values and can also produce the next prospective point on the graph according to the trend it is averaging out.  A proportional model also creates a line that has proportional variables. That is, if the independent variable is doubles, so d...

      Our most recent investigation was the perfect example of classical mechanics and how it works. We know that the force of an object is equal to mass x acceleration, which in this case the acceleration would be equal to gravity. Knowing this, Newton's second law of motion, we can predict that there will be some sort of linear relationship in everything we interact with on a daily basis, when we measure force of course.      In the aforementioned investigation that was cleverly named "Ziplock Zoomer", we tested the relationship of force and mass using quarters, a ziplock back, paper clip, and IOLab. We recorded our data in logger pro and created two graph based on our information. So how did this all go down? Well, we hooked up our IOLab and prepped it by calibrating it, then we used a paper clip to hang a ziplock back from the IOLab and used the ziplock bag to hold the quarters we were using in this experiment. We recorded our results qua...

     As humans, more often than not, we let our days pass on by without really stopping and taking time to observe our surroundings-whether it be to look up at the sky or see the cars passing by on the street, to hear kids laughing, running, and playing, or to hear the howling of the wind on a windy or stormy day. We sometimes tend to forget that the basic reasons behind why these things are even possible, can be explained by science. Physics gets to the fundamental level of how and why things move the way they do. In STP, we conducted an experiment using IOLab and documented it in LoggerPro. We used our "brick" on wheels and placed it at different heights to see the relationship between height and velocity. In order to record information, however, there were a few things that needed to be agreed upon...     We were placed in groups, and in those groups, a whole bunch of brainstorming went down on what things could potentially affect our results and what the eff...

  Define the word “science.” What is  it?      Science, in the simplest form, means knowledge . Whether it be to obtain information, to discover new information, or even to gain insight on a subject, one adds on to existing knowledge or, simply, becomes more knowledgable.       For example, the word "geology" can be broken down into two parts: "geo" meaning "earth" or "rock"  and "-logy" comes from the Greek "logia" which means "the study of". When one studies, one gains knowledge or reinforces the knowledge that is already there, at least I would hope. ___________________________________________________________ Is Umbrellaology a science? If so, why? If not, how does it fall short of being a science? Technically speaking, it is a science, but to an extent. It is a science because whoever was conducting the investigation learned deeply about umbrellas, the mechanics of it, its uses and applications, etc. However, the...
