on the rate evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent: o Surface area in cm2 of the top most surface of water in the container. - Dependent: o Rate of evaporation

xxx1 xxxxxx Ms. xxxx Biology 20 November 2013 Osmosis Lab Problem: What’s the order of the concentration for each solution and how does it affect the movement of water? Hypothesis: Experimenter thinks the order of the solutions according to their concentration is D‚A‚E‚C‚B‚ from smallest. And the water will pass through semipermeable tubing bag from low to high concentration to thin the concentration inside the bag. Osmosis is a diffusion of water particles and is one of the passive transport

Osmosis using potato cores and sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell

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

In the article‚ " The Egg and the Sperm" by Emily Martin‚ the author attempts to shed light on the gender stereotypes hidden within the scientific language of our biology textbooks. I found this article to be very intriguing because‚ as a nursing student‚ I’ve been exposed to many medical and biology textbooks and it has never occurred to me that cultural beliefs could influence how a biologist described their discoveries. I had no idea that within the scientific accounts of reproductive biology

Are naked eggs with no shell? What? You may think I am speaking about a hard boiled egg‚ but‚ no. Boiled eggs have their centers heated making the shell easily come off. Naked eggs have their shells taken off with one simple ingredient everyone has. Vinegar. The vinegar acid inside the vinegar strips the shell away from the egg. The vinegar solutions dissolves the shell from the egg. Once the egg has been separated form it’s shell the only thing keeping the liquid goo inside is the thin‚ flexible
