Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room

Diffusion and Osmosis Worksheet Diffusion is the movement of particles from areas of higher concentration to areas of lower concentration. It is a natural‚ random process. This means that it does not require extra energy input. 1a. These are pictures of molecules frozen at two different times. Draw arrows to show the direction each particle might travel due to diffusion in diagrams A and B. A. B. Random arrows Random arrows 1b. Describe the way the particles

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:

will start seeing quite a few sales on eggs. Why? Eggs are one of the main staples in the Easter holiday tradition. Everyone gets together the night before Easter and colors their eggs a wide range of colors to put in their Easter baskets for the Easter Bunny to hide.

“Egg Baby” – What did I learn by caring for mine? This project gave me a sneak peak on what it’s going to be like as a parent‚ but not even close to the real thing. At first I thought this project was going to be a breeze‚ but once I got into it I was all wrong. Taking my egg‚ Lily‚ everywhere with me was a pain. I had to worry about her “baby seat” and make sure it was safe for her. Going through the crowded halls at school was quite difficult also. I had to make sure she was close by my

you must be able to understand what the poet is trying to reveal to you. Luckily I understood very well what the poet was trying to communicate when I read “egg horror poem”‚ by Laurel Winter. I believe that Winter wanted to make the reader feel as if they were one of the eggs‚ feeling all of the suspenseful emotions that come with being an egg‚ she does this by using imagery words‚ voice‚ and her ideas. This involves making me feel like I am waiting in a carton with my friends‚ waiting for the fridge

EGG DROP PROJECT Using principles of physics‚ design and construct a container for a raw egg that can be dropped from the second story balcony of St. Joseph’s Academy and strike the ground without breaking the egg. The finished container must meet the following criteria: No professional packing materials (such as bubble wrap or Styrofoam peanuts) may be used. The egg must be raw and either Large or X-Large. If a parachute is attached to the container‚ it must be made from

Egg shell as face powder (related literature) Eggshells are composed of around 95% calcium carbonate‚ a mineral that is very important for industry‚ nutrition and agriculture. There are many studies trying to find new ways to utilize this resource and their natural absorbent properties‚ as in treating cadmium in wastewater. So‚ never toss out those egg shells. They’re not garbage‚ but can be very useful around the house and yard. They also help to save you money by replacing many expensive‚ toxic
