APPENDIX 5 - Writing Reports Report 1: Drosophila F1 Generation Report General Notes: This report is very much a practice run to get you used to this style of report writing‚ rather than simply filling in lab sheets. It should not be a long report (no longer than these notes‚ in fact). Scientific writing is not like writing essays in other genre. In many ways it is easier! There are three important rules to scientific writing and if you adhere to these‚ the rest is quite easy: 1. Sentences

Walking‚ Skipping‚ and Running on the Heart Rate Due Date: Friday‚ November 23rd‚ 2012 Question: What is the effect of walking‚ skipping‚ and running on a person’s heart rate? Hypothesis: If the intensity of the action increases (walking<skipping<running)‚ then the heart rate will also increase because the faster the legs are moving‚ the faster the leg muscles need to contract. When the leg muscles contract faster‚ more energy is used‚ and the heart will pump faster to deliver oxygen

dilation of blood vessels decreases the amount of venous return to the heart. Also‚ this increased diameter of blood vessels and increased volume allows for less of the blood to come in contact with the walls of the vessels. So a larger volume of blood is allowed to pass through a vessel without obstruction‚ characterizing a decrease in peripheral resistance. This increased blood flow is explained by an immediate increase in heart rate‚ which is what allows for more blood to pass through the vessels.

IntroductionThe purpose of this experiment is to determine whether or not caffeine has an affect on the heart rate of DaphniaHypothesisThe Daphnia heart rate will increase with the concentration of caffeine. I based my hypothesis on the fact that humans heart rates increase with caffeine as it acts as a stimulant drug. In the experiment there will be several variables that I need to try and control‚ the temperature of the water is one of these because if the temperature is higher or lower on the

Finding the rate law was the overall goal of the laboratory. When finding the wavelength of the Azo Orange II dye‚ the highest wave was the point used‚ 483nm. The plotted points of the different concentrations absorbance’s made sense to have a steady upward slope because the dye was diluted in steady increments from full to ¾ and so on. Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were

Fundamentals of Lab reports (Students hard copy-guidance) Task Students will receive a lab manual at the beginning of the semster. This manual is expected to cover the safety‚ instruction and details of the experimental work during the lab sessions. All students should read the experiment before coming to the laboratory. The teaching assistant will discuss the safety precautions‚ experimental procedures and techniques involved in the lab session. The students should conduct the experimental

Metabolic rate refers to the “amount of oxygen consumed by the body cells” (Farlex‚ n.d.). it can be affected by numerous factors‚ some of which being the mass of the animal‚ its physical activity and temperature. Invertebrates are able to live in highly variable conditions due to their metabolism having evolved over time. Homeotherms are animals that are able to maintain a specific body temperature without relying on the temperature from its surroundings. Poikilotherms on the other hand do the exact

The Scientific Method - The Scientific Method is the standardized procedure that scientists are supposed to follow when conducting experiments‚ in order to try to construct a reliable‚ consistent‚ and non-arbitrary representation of our surroundings. To follow the Scientific Method is to stick very tightly to a order of experimentation. First‚ the scientist must observe the phenomenon of interest. Next‚ the scientist must propose a hypothesis‚ or idea in which the experiments will be based around

1.03 Scientific Method Kaylee Mellott August 23‚ 2013 Scenario 2: 1. The dependent variable is the rate of the growth of the plant and then the independent variable would be the time of day that she waters the plant. 2. Five variables that should be controlled during the experiment is the amount of sunlight‚ room temperature‚ amount of water‚ the time of day the plant is watered and the certain type of plant. To make sure the plants get the same amount of sunlight‚ make sure to put them both
