Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

The Development Of the Egg and Sperm your name PSY/265 May 20‚ 2012 Nicole Pansey The sperm and the egg are the key to reproduction. Without the sperm fertilizing the egg there would no reproduction. They both start off in very different places and in different ways but come together to create a life. The journey to create a life is a very interesting one and in this paper I will be outlining it in detail‚ describing the male and female sex organs and the role of both these

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

Pages 4 – 7: Preliminary Experiment Pages 8 - 14: Main Experiment Introduction In this experiment I am going to investigate the effect of varying concentration of a differing glucose solution on the amount of osmotic activity‚ between the solution and a potato tuber of a given size. The purpose of this experiment is to demonstrate how living cells rely on osmosis‚ the diffusion of water. Osmosis is the movement of water

The effects of osmosis on potatoes placed in different salt concentration Introduction: Osmosis is a movement of water across a semi-permeable membrane. This may only happen when there is a difference in concentration between the two sides of the membrane. The water moves from low concentrations to high concentrations. That is because the low concentrated area tries to dilute the opposite via osmosis. The effects osmosis has on a cell are either that it becomes turgid and hard as water enters

Sperm and Egg Donation Many children will never know anything about their biological background‚ because their mother had a sperm or egg donation. Is that fair to children because their mother made that choice? Everybody deserves to know where they came from‚ and what risks they could suffer in life. For example heart disease‚ Parkinson’s disease‚ degenerative diseases‚ these are just some of the common diseases that could be genetic. Some offspring’s may just want to know their culture and history

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

In order for your life to be great you must first learn to appreciate it. This theme reflects in the fables “The Goose That Laid the Golden Egg”‚ by Nicky Grischotti and “The Dog and His Reflection”‚ by Tony Payne they both show that you should appreciate what you have and to not be greedy for more. In “The Goose That Laid the Golden Egg”‚ the theme‚ don’t be greedy and appreciate what you have‚ is shown from beginning to the end. For instance‚ Atticus Greeb‚ the main character‚ inherits a large

Arianna Montoya Osmosis and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane
