GS104 Lab Report Experiment # 2 Data Collection David Case: January 23‚ 2015 Experiment #2 Data Collection Objectives: Exercise 1: Formulating a Hypothesis about pitching speed. To form a hypothesis for the pitching velocity of a ball. Use a spreadsheet and math to calculate the actual velocity and determine the accuracy of the hypothesis. I will also roll a large ball to measure its velocity and graph its horizontal motion. Materials: Volley

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

Osmosis Lab: The Incredible Egg How does the solution a cell is in effect the movement of substances into and out of the cell? Eggs were soaked in vinegar for twenty-four hours before the lab to dissolve the shell‚ then placed them into the distilled water. Then the eggs were taken out and dried by the paper towel to measure their weight on the electronic scale. First egg weighted 78.92g‚ most of the parts of it’s skin was white translucent‚ and was spongy. After the egg was submerged into the

transport of materials needed for survival. Cell membranes aren’t in just one specific kind of cell because it’s in every cell. The cell membrane is supposed to hold up the structure of the cell keeping all organisms in alignment. Osmosis is the movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in order to equalize the solute concentrations on the two sides. We didn ’t know anything about osmosis except that it was a word in the dictionary

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying

TRANSPIRATION DESIGN LAB Transpiration is the process through which water is lost from a plant. Water is taken into a plant through roots and root hairs by osmosis‚ and it exits the plant through stomata. Transpiration helps the diffusion of both O2 and CO2 plus it helps the movement of water throughout the plant. There are some factors that affect the rate of transpiration of the plant. Those factors are mainly humidity‚ soil water supply‚ sunlight‚ temperature and wind. Any alteration

Khilafat Movement was a religio-political Movement propelled by the Muslims of the British India for the maintenance of the Ottoman Caliphate or khilafat-e-usmania and for not releasing for the Muslim blessed places under the control of the Non-Muslims. Amid the 1st World War Turkey agreed with Germany and as Germany began to free Turkey likewise began loosing its domain. When 1st World War reached an end in 1918 Turkey had lost the majority of its domain. Accordingly the issue around then was the

The Chicano Movement‚ like many other civil rights movements‚ it gained motivation from the everyday struggles that the people had to get by in the United States due to society constantly pushing them off to the side. Mexican-Americans‚ like many other ethnicities‚ were viewed as an inferior group compared to the white Americans. During this movement‚ there were a lot of important actions that took place from farm worker rights‚ education‚ and the political movement that change the course of how

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each
