**IF YOU ARE USING THIS** please note that this was an experiment conducted by me and my lab partner. Due to the fact that she wrote the materials/methods section and the abstract, I have not included it. This is only results and analysis for a diffusion lab for a Biology400 college class. Please do not copy and paste, it is PLAGIARISM. Only use for clarification of analyzed results. Results Figure 1a. The following table includes the circumference of the circle that was created by the diffusion

experiment. Without the procedure no one would know what to do and I can assume that experiment won’t turn out so good. Observations, observations are split up into two groups quantitative and qualitative. Quantitative is things measured by volume, mass, numbers, and length. Qualitative is what is observed during the experiment using all 4 senses (see, hear, smell, feel). Conclusion is the second last part to write in a lab, it is telling us if the prediction was correct, and what your group noticed

Stage 1 Physics Practical- motion Aim: To investigate the speeds of different moving objects. Hypothesis: If the ball is heavier then it will longer to cover a distance, therefore it will travel at a slower speed. Variables: Independent- The independent variable that was established before the practical was the weight of the ball. Dependent- Where the dependent variable relying on the independent variable was the time taken for the ball to travel a certain distance. Controlled-The

precision of the micropipetters that you plan to use. A very simple way to do this is by weighing the volume of water actually transferred by a micropipetter at a given setting. Water has a density of 0.9986 g/mL at room temperature, so you can use the mass of the water transferred to determine the accuracy of your pipetter (as long as your balance is reliable of course....), and by repeating the test several times, you can determine the precision of the micropetter as well. Procedure: 1. Using a balance

Benjamin Crowell THE MOTION OF FALLING OBJECTS The motion of falling objects is the simplest and most common example of motion with changing velocity. The early pioneers of physics had a correct intuition that the way things drop was a message directly from Nature herself about how the universe worked. Other examples seem less likely to have deep significance. A walking person who speeds up is making a conscious choice. If one stretch of a river flows more rapidly than

kilograms) =9.07kg | 2. State the law of mass and energy conservation. Describe how you might demonstrate this law. The law of conservation of energy, is when the total amount of energy remains constant, but can change forms from one to another. The law of conservation of mass is when the total amount of mass remains constant, even if you change the shape or the chemical make up. I would demonstrate this law by proving how the energy and mass stays constant. 3. Adapted from Exercise

from splitting in half from dropping. I also put some paper in it so that the egg will be more protected when it drops on the ground. This experiment relate to Newton’s second law which is the sum of forces equal mass x acceleration. The force that the egg hits the ground will equal the mass of the egg. It also relates to Newton’s third law which is for every action, there is an equal and opposite reaction. Whatever object the egg hits, a force will be exerted on the egg that is equal to the force of

Aristotle was perhaps the first in the Western tradition to look at mechanics in any sort of structured way. A philosopher, rather than physicist, Aristotle thought about the way objects interact with each other, particularly their motions. One of the ideas to come from Aristotle’s work is that objects “like” to remain at rest. This seems rather reasonable put a book on a table and it remains still, push it gently and it will move until you stop. This begs the question, though what happens when

Date : 17 September 2015 Venue : Farm Two Activity : Basic Feed Before we head to Farm 2, Dr. Tee gave us a minute of lecture on the theory of feed before we actually do the hands on. In the lecture, she told us that feed contribute to 50 %-70% of cost production. The cost and the price can be fluctuate according to the price set by producer for instance, the USA company. Dr. Tee also taught us on how to calculate the feed cost. Example 1: 1 kg = 10% of wet basis 10/100 x 1 kg =
