because the fan cart gives off a constant force. The result that we got for work in the four trials is increasing from the first trial to the last trial because we increases the distance it covers and the work is the product of the force and the distance covered by the object. And the power is the rate at which the work is done it is the work done per unit of time which is second. We got the values of power by dividing the work by the time we got in the smart timer reading. And in table 2‚ we measure

The human cardiovascular system consists of the heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

Effects of Temperature on the Formation of Cheese Curds This lab was performed in order to find what temperature the enzyme chymosin is most effective at forming cheese curds. An enzyme is a protein that acts as a catalyst to speed up biological reactions in cells. They work by lowering the activation energy and help to orient the molecules correctly. Chymosin was originally taken from the stomachs of calves‚ and was called rennet‚ and then purified to make rennin. Eventually to catch up with
