the beaker of water for a longer period of time‚ then more water will travel through the selectively permeable membrane due to the effects of diffusion on the solution. If the level of sucrose within the solution increases‚ then the effects of osmosis will cause the change in mass to also increase due to higher concentrations of sucrose and the increased net movement of the water molecules within the solution.

My First Lab Report: Diffusion and Osmosis To begin‚ this is my first time doing an experiment and a lab report for biology’s class. Although‚ it was a little hard at the beginning‚ my team and I got the hang of it and we finished it on time. It was actually kind of fun. There were three steps in the experiment: 3.1 A – Molecular Movement: In this session‚ I was observing a sample and determining if there was a movement or not. 3.1B –Diffusion through semi-permeable membrane dialysis tube: In this

Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

shows that although the common belief is that reading will make us better people‚ it doesn’t mean anything to us unless we really know how to comprehend the book itself and allow it to influence our decisions. A text that applies to this idea is A Raisin in the Sun. It is just a normal book until you take it to a new realization and apply it to much more. Through this book‚ I have learned how characters are influenced by their surroundings‚ how pieces of the book connect to this quote‚ and how my

white girls are walk together as sisters and brothers.” Martin Luther King Jr. In the play “A Raisin In A Sun” by Lorraine Hansberry is essentially about dreams‚ including the American Dream. The play takes place around the 1950’s in Chicago’s south side‚ when segregation was still around. In this play you meet a cast of people with dreams of a better life that compares the novel "A Raisin in the Sun" with Martin Luther King’s speech "I Have a Dream." It Analyzes the similar themes found in

The term despair means ‘the complete loss or absence of hope’ which is what South Side Chicago mirrored in the novel A Raisin in the Sun. Just by looking around you could tell that all hope was lost when there’s widespread poverty on Chicago’s South Side. Also by taking a look around the Younger home you can see it in the faces of people -- and the furniture?! On the first few pages opening Act I‚ Scene I‚ the text says “Now the once loved pattern of the couch upholstery has to fight to show itself

Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.

As discussed in the intro‚ the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions‚ with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass‚ the 0.5 M egg with 10.39%‚ and the 1 M egg with the least

Referring to the latest version of A Raisin in the Sun (2008) it is set on the Southside of Chicago‚ Illinois. In the film‚ the head of the household is Lena Younger (Phylicia Rashad)‚ who the family calls‚ “Mama.” Mama’s husband‚ Walter Sr. has passed away so a settlement for $10‚000 from his life insurance policy is being mailed to her. Walter Jr. (Sean Combs) and Beneatha (Sanaa Lathan) are Mama’s children and they believe the check should be given to either of them for medical school or an investment
