Osmosis and the Egg Lab Report By: N. Mullins Date: January 20‚ 2011 Introduction This lab was designed to explain the different things osmosis does. Osmosis is the diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually

AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

1. EGG INOCULATION The fertile hen’s egg can be used to cultivate and propagate various types of viruses. Because of the ability to alter their tropism and to adapt to a new host species‚ many viruses become capable of growing in chick embryo tissues wherein they frequently attain a much higher concentration than in the tissues of the natural host. STRUCTURE OF AN EGG The extra-embryonic membranes of the chick embryo arise from three germinal layers: the endoderm‚ mesoderm and ectoderm

embryonated broiler chicken eggs. Group A is negative control with no haemagglutination activity and group B as positive control with positive Haemagglutination activity. For each drug to be tested‚ 40 eggs were assigned to 8 groups (i.e. A‚ B‚ C1‚ C2‚ C3‚ D1‚ D2‚ D3) with 5 eggs in each group. Embryonated eggs in each of C1‚ C2 and C3 subgroups were treated only with 3 different concentrations of each compound to evaluate toxicity respectively. Whereas embryonated eggs of SUBGROUPS D1‚ D2 and

Name: Modella Studente POW # 1 Broken Eggs Problem Statement: How many eggs were broken? (And is there more than one answer?) Process: Given that she lined them up by twos and one was left over‚ by threes and one was left over‚ by fours and one was left over‚ by fives and one was left over‚ by sixes and one was left over and by sevens and it came out evenly‚ we figure the number had to be a multiple of seven and end in a one or a six. (Anything divisible by five with one left over has to

Would you sell your eggs for money? Is it ethical for a woman to undergo hormonal and surgical treatment to donate eggs to another infertile woman‚ for money? Is it ethical for the couple to pay for certain characteristics‚ such as intelligence‚ sportiness or good looks? Today‚ many women‚ and couples are not able to conceive‚ which causes them to seek other options in order to start their family. When couples realize that they are infertile‚ they face several solutions. Some couples decide to

Running head: Egg Drop Lab Report Egg Drop Lab Report Jon Johnson Rochester Area High School Egg Drop Lab Report Introduction The objective of this project was to create a structure that will protect a raw egg and prevent it from breaking when being dropped from a minimum height of two meters. A decent hypothesis or prediction one could develop before any experimental trials would be as follows. The structure that provides the longest duration of impact between the falling egg the ground

Colors of Food Coloring Are Soaked into a Naked Egg‚ Will the Mass Change Depending on the Color of the Ink after 7 Days? The Purpose The purpose of initiating this lab was to test how different chemicals in the outer fluid affects the osmotic properties of a naked egg. Background Information In order to complete this experiment‚ one of the most important things you need to know how to do is how to take the outer “shell” layer off of the egg. The egg shells contain an element known as calcium carbonate

Egg flotation Objective/Question/Problem My objective is to see which egg will float. The question is how much salt is needed to be added to make the egg float. The problem is that I do not know how much salt is needed to make an egg float. Hypothesis If I add salt to the water then the egg will float because the egg has a density that is lower that the density of the fluid it displaces. Background Information If the object has a density that is higher than

protect a raw egg as it falls to the ground from a height of 8 feet. Your team will receive an egg and a bag of materials. You will be given time to brainstorm how you might construct a protective mechanism for dropping your egg without breaking it. You are only allowed to use the materials in your bag within the time frame allotted. It will be important to work well with your teams in analyzing the materials you are given and predicting which materials will safely protect your egg during its descent
