1. Lab Report - Density and Composition
An experiment of measurement, in which we will measure the length from a persons back of the knee to their heel, then measure their height and plot the results on to a graph to show any relationship between the height and the length of the leg. .
B. The experiment being conducted is to see if there is any relationship between how tall a person and the length of their leg and whether or not the results are consistent.
C. The longer the length from the back of knee to the heel, the taller the person will be in relationship to that length.
2.Procedure.
A. The equipment consists of a meter stick, a chair, graphing paper to plot the results.
B. We measured the length of 4 people's legs from the back of the knee to the end of the heel. A person kneeled on to the chair placing their leg into a 90-degree angle. The meter stick was used to measure the length from the back of the knee to the heel of each person. Next everyone's height was then measured with the meter stick. Last we recorded the data and plotted the results on the graph. .
3.Results .
A. Graph is attached to lab report.
B. On the graph is the height of a person and the length of their leg plotted in an organized manner to easily see if there is or is not a relationship between the height and length of each person.
4.Discussion.
A. The hypothesis failed to be accurate. The relationship between the height and the length of the people participating in the experiment did not coincide with the hypothesis.
B. The data recorded showed no particular pattern or relationship between the participants and their measurements. .
C. In conclusion, the initial hypothesis failed to be accurate. Our hypothesis could be more accurate if we used more participants and broke them down into categories by their genetic makeup. (Example: sex, weight, hair color, etc.).
Implementations of things like libraries, computer labs, or scientific labs increase test scores in reading and mathematics (Severin, Eugenio). ... The only question is, which piece of infrastructure is best to implement: computer labs, libraries, or scientific labs? Methodology The three different pieces of infrastructure that we decided to examine were: computer labs, libraries, and scientific labs. ... There were three research reports that were examined to collect useful information. ... The report when on to describe how laptops resulted in higher test scores (Duarte et Al). ...
Lab Report for Chemical Reactions Experiment Objective: In this experiment students will attempt a number of different reactions. The students will confirm that a reaction did/did not occur by detailed observation, and predict the products of each reaction by performing basic tests. Hypoth...
Pre-Lab Part A: 1. ... Cell wall- protects the cell Plasma membrane- boundary between cell and environment Nucleolus- makes ribosomes Chloroplast- captures light Cytoplasm- clear gelatinous fluid Pre-Lab Part B: 1. ... We did make an error in the process of the lab. ...
LAB QUESTIONS 1. ... There are many small factors that could have contributed to error in this lab. ... EVALUATION This lab was a good lab to start the year off with. ... What this lab taught me about mass, volume, and density. ... This lab will prepare you for other labs cause it taught you the basic skills you need to know. ...
LAB: DETERMINING THE VALUE OF THE UNIVERSAL GAS CONSTANT, R. Objective: The objectives of this lab are to measure the volume, pressure and temperature of a sample of wet butane gas, C4H10 grams. ... Put on safety glasses and keep on until you complete the lab. 2. ... Obtain butane lighter from your instructor v/s NO NOT LIGHT AT ANY TIME DURING THE LAB. 6. ... As one partner holds the graduated cylinder (inverted), the other lab partner should hold the butane lighter under the water just below the opening of the graduated cylinder is equal the level outside when finished. 8. ...
Teaching as My Career For the last twelve years or so, I have been going to school. Every single day I find myself behind a desk doing schoolwork. Day in and day out it is the same thing, come to school, do some work, leave school to go home, and when I get home, I do even more work. But this...
Our objective for this lab was to study the rate of movement of stentor in contrast with different water temperatures. ... Materials and Methods To begin the lab we obtained a gridded depression slide and applied Vaseline outlining the grid. ... These graphs show the lab on a much larger scale in contrast with the group graphs. It is another view on testing this lab to get the most plausible outcome. ... Next time we perform this lab we would try to keep the water at a constant temperature and measure the movements a little more precise....
This lab was done to look at the properties of covalent and ionic compound. ... Experimental The material used in this lab was test tubes, distilled water, a 250 mL beaker, a hot plate, a stirring rod, and some samples of Sodium Chloride. ...
