Chicken pox is an extremely transmittable disease easily noticeable by the particular rash that it causes‚ which happens mainly in kids. Most people will get chickenpox at some point in their lives if they have not had the chickenpox vaccine. Chickenpox

Osmosis is the diffusion of water molecules across a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration‚ to an area of low concentration. So‚ Osmosis is the movement of water molecules from an area where there are lots of water molecules to an area where there are few water molecules. Our aim is to find the concentration of dissolved substances in the cells of a potato using Osmosis. I predict that the potato in the higher concentration of salt

Osmosis Trial experiment Aim: Our aim in this experiment is to find out which vegetable absorbs the most liquid over a given time due to osmosis. Chosen Apparatus: we will need to use: six test tubes; a test tube rack; an apple; a potato; a cork borer; a measuring cylinder; sugar solution; scales to measure in milligrams; a ruler; a knife; and a pair of tweezers. Apparatus Why we chose it Advantages Alternative equipment apple Its an absorbent fruit and is similar to a potato It

Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

The East Egg is the place those with old cash live‚ and the West Egg is the place the independent‚ rich individuals live. While individuals living in the East Egg procured their cash through legacy and effortlessly‚ those living in the West Egg obtained theirs through diligent work. In spite of the fact that they may have become well off through illicit means‚ they have held

“Pepin debone chicken” In this paper I will be giving you my response to the video “Pepin debone chicken” by Jacques Pepin. I will be discussing my view on Chef Jacques Pepin video on how to debone chicken‚ as well as the benefits of using his technique. In my opinion‚ Chef Jacques video for deboning chicken makes it look far easier than I would have thought. I watched the video several times‚ and no matter how many times I watched it‚ it always intrigues me. I wonder how many chickens Chef Jacques

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

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
