Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.
Next I measured 50 milliliters of distilled water into a graduated cylinder and poured it into the beaker filled with the guar gum. I mixed it together until the guar gum was dissolved in the water. Then I measured four milliliters of 4% Borax solution into a graduated cylinder and added it to the mixture. I then stirred it until it became slime. Finally, I poured it into my hands to feel its consistency and viscosity.
People like math and science because they require critical thinking and problem solving. Otniel E. Dror from The University of Chicago Press on The Reflection on Feelings, talks about why people love conducting dangerous science experiments. His studies found people enjoy doing critical science experiments because it gives them an adrenaline rush. In Trinity, Fetter-Vorm takes his audience on a nerve racking journey through various science experiments used to create the world’s first atomic bomb. Fetter-Vorm constantly described the life or death situations scientists were put in making the bomb.
The article written by Brian Rohrig titled, NASCAR: Chemistry on the Fast Track, released in the February 2007 issue of ChemMatters, tackles the interesting challenge of relating racing to chemistry. Throughout the article, Brian uses the technology and equipment utilized in the sport to draw connections between the general field of chemistry and NASCAR, a famous North American racing series, whilst explaining the general rules and regulations unique to the NASCAR series. Many individuals today seem to forget that science is not only found in a textbook, research paper, or lab. Science is present in our world everywhere, whether it is racing, gaming, or simply breathing. Chemistry can also be found in every single interaction in the universe,
This experiment was created to contrast the effects of osmosis between three gummy bears in tap, sugar, and salt water. To compare the gummy bears, three cups were gathered and filled with twenty-five milliliters of the particular water solution. Then the mass and volume of each gummy bear was recorded into a chart. To find the mass, zero a balance once a strip of wax paper is placed over, and then place your gummy bear and record the mass. To find the volume of the bear, multiply the length, width, and height of the bear in centimeters with the help of a ruler.
Science is something people have confidence in because they know that when science is involved in a study, that they study is
The essay “Science: It’s Just not Fair”, by Dave Barry, some truths about science fairs that many students have to participate in are brought out. Barry starts the essay with the beginning of the science fair project process, which is usually put off until the last minute. He sarcastically and ironically describes the process as a student who is rushing to do their project the night before the due date. Barry also includes and comments on the the ironic importance of the hypothesis and conclusion in the science fair process, showing how they usually very vague statements. He also gives examples of his wife’s and his own last-minute science fair projects that they threw together quickly before the due date.
Science and technology have had a major impact on society. It has changed the way we interact, transport, and can even change the length and quality of life itself. Science has changed our learning abilities too, we now have ipads at our elementary school and it helps students
Ever since I was little, being on Clearfield High School drill team was always a big dream of mine since I saw them perform at multiple of their schools football and basketball games. My parents took me to my first dance class when I was three years old and ever since I fell in love with that particular sport. I was different from all of the other kids at my school because they always got to play with the other kids from school and I always ended up having dance, but I didn’t mind because that was where most of my really close friends was at my childhood dance studio. I grew really attached to everything about that studio.
Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.
Materials 1 calibrated thermometer, 1 scale that reads mass, 2 Styrofoam cups, 1 small lead sinker, boiling water in a beaker, 1 pair of kitchen tongs, 1 small cooking pot, stove top, distilled water, and 1 pair of safety goggles (I did not use a cork stopper). III. Procedure First, the beaker
Utilizing the method that the experimenters have come up with, the procedure isolates the variable being tested, which is the paper towel brand. By not changing other aspects of the procedure, other factors have a lower chance of affecting the accurate results of the answer to the main question. Additionally, the method is a quick and simple experiment, causing no use of excessive time than the provided duration. Within the first minutes of the experiment, the experimenters and the advisor realized that the method did not really provide accurate results due to merely estimating the numbers without the use of a graduated cylinder. Changing that aspect of the procedure by using a graduated cylinder to measure the amounts of water instead helped
This experiment has to be carried out carefully
Abstract — This experiment was conducted to familiarize the students with the procedures regarding distillation—to be more precise, the separation of ethanol from an alcoholic beverage—using a distillation set-up consisting of boiling chips, a Bunsen burner, a condenser, a thermometer and several other materials. In the end, it was discovered that one may actually separate a homogeneous mixture, given that the components of said mixture differ in volatility and that they utilize a complete distillation set-up and follow laboratory safety rules and regulations. Keywords — Matter, homogeneous and hetereogeneous mixtures, distillation, volatility, boiling point I. INTRODUCTION There are typically two categories of matter, these are pure substances
Like Water for Chocolate If you cannot take the heat, get the heck out of the kitchen! Like Water for Chocolate is Mexican, romantic folktale written by Laura Esquivel. This novel tells a story of Tita De La Garza (and her family), whose life is centered around the kitchen, heartache, pain, disappointment and forbidden love as a result of family traditions.
