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

Egg Drop (lab writes) In our science class we did an egg drop experiment. We used the scientific method to answer the question and solve the problem. Our question for this particular lab was “will an egg break or be secured‚ if covered with thick sponges and drop from ten feet above the ground?” our idea was to secure the egg from breaking and we wanted to design something that would provide a lot of cushioning directly on the egg. We came up with many different ideas until we choose

The Egg Drop Analysis 1. As far as researching goes I did not do many research besides videos I mainly saw a lot of sponges or big sponges use for people experiment and I in fact went with it and prototypes I used were mainly the same thing with some added cushion to it. 2. I forgot to take a picture but a good description would definitely be a can and thats wrap in cushion on the inside and the outside but the error I made was not covering the metal shock that will it takes impact it release

March 4‚ 2010 Egg Buoyancy and Density: Can you make an egg float by changing the density of water? If you put an egg in tap water‚ it will sink to the bottom. If you add enough salt‚ the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge. Anyone
Premium Density Sink Egg
Method: The eggs were soaked in vinegar for 48 hours. At the end of this period the eggs are dried off and mass is recorded. The eggs are then placed in distilled water. They are removed and the mass recorded. Lastly the eggs are put into corn syrup and again removed and the mass recorded. Results: The egg in the vinegar got bigger‚ as the fluid moved into the egg‚ and the fluid level went down. This is an example of a hypertonic solution. In the distilled water the egg got slightly larger

Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

A male has external and internal sex organs. The external sex organs for the male consist of the penis and the scrotum (also known as the ball sack). The internal sex organs of a man consist

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

While some people claim that is inhumane‚ families who had to deal with dangerously ill patients at least had a choice and knew where the patient was and that there would be some kind of treatment. Now we have multitudes of homeless people on the streets‚ and many of them are mentally ill. They can
