Lab 1: Diffusion & Osmosis 9/16/14-9/19/14; Jessica Bullock‚ Andrew Buchholz‚ Kristamae Masiclat TITLE: Different Ways to Express Diffusion and Osmosis INTRODUCTION: Diffusion is the spontaneous movement of a substance down its concentration gradient‚ from a region where it is more concentrated to a region where it is less concentrated. Osmosis is the diffusion of water across a selectively permeable membrane. The objective of this lab is to observe the different effects of diffusion and osmosis

mythelin blue affects the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can affect the rate of diffusion‚ as a higher/lower temperature

Introduction In Diffusion‚ Dialysis & Osmosis lab‚ we discovered that we were going to observe and understand the conditions under which diffusion‚ dialysis‚ and osmosis occur. Then we constructed models of diffusion‚ dialysis‚ and osmosis. We predicted that the direction of change would be from the membrane to the beaker. We understood how these processes affected the selectivity of the cell membrane. The second part of the lab was dealing with dialysis. In this part we studied starch and sodium

Hair Dye Side Effects You Should Know The hair dye side effects are huge in number. Do you see your most loved big name get their hair colored and regularly wind up giving into the prevailing fashion? While coloring hair is fun‚ there are a considerable hair dye side effects that you should know about. The hair dye side effects and harm brought on may not generally show up quickly. It might take up to a few days or even weeks after hair coloring sessions. Particularly in the situation that you color

The Technology-Diffusion Model illustrates how a social institution reacts to a new technology as follows: • “Innovative technology is created • Institution adopts technology to carry out existing functions more efficiently • Institution accommodates internally to take better advantage of new efficiencies • Institution develops new functions and activities made possible by capabilities of the technology • Institution may become obsolete‚ be replaced‚ or be radically transformed • Other institutions

Experiment: At this experiment we are investigating does the temperature affect how quickly the particles diffuse to an even concentration throughout the water‚ we are going to do this experiment by using food coloring to see how quick the food coloring diffuse in hot water and cold water. Materials: • • • • • • • • One beaker Hot plate Ice Water Food coloring Thermometer Timer Eye dropper Hypothesis:I think the food coloring will spread faster‚ because the particle in the hot water have more

Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous
