Osmosis and Diffusion (Dakara DaCosta)

This picture decribes Osmosis. Osmosis is the movement of water across a cell membrane. In this picture the Eggs are the cells and the egg whites are the semi- permeable membrane . The seasoned water will travel inside the eggs through the membrane. Thus, making the eggs tasty! 

This window screen describes a Semi-Permeable membrane. Semi- permeable membranes only allow certain molecules to enter it. This window screen is very similar. It allows air to enter but does not let flies & mosquitos & other bugs through. 

This perfume describes Diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. If I apply this perfume in the living room all over my body, my mom will soon be able to smell it in the kitchen when she is cooking. This describes diffusion because at first I could only smell it in the living room (high concentration), but then it traveled into the kitchen where you could not smell it at first (low concentration). 

This picture describes a hypotonic solution. A hypotonic solution is when there is more solute than solvent. The salt in this picture is the solute. The solvent is the water. It is only 1/4 cup of water in the container and that is a 1 pound can of salt that will be poured in the container. This a hypotonic solution because there is more salt than water.

  

 This picture describes a hypertonic solution. A hypertonic solution is when there is more solvent than solute. This table spoon of salt (the solute) is being poured into this giant pot of water that weighs about 4 pounds. This is a hypertonic solution because there is more water than salt.
