Bayfield Mud Company DISCUSSION QUESTIONS 1. What is your analysis of the bag weight problem? The problem begin when Wet-Land Drilling‚ Inc. had filed a complaint that the bags it received from Bayfield were short-weight‚ according to previous send the weight of the bags used to be 50 pounds‚ however the new arrivals show a weight of 47.5 pounds per bag‚ causing a conflict to the company. The company present the problem as a increased of demand‚ hiring new employees with a lack of training

gathered; approximately 2 inches in length‚ sewing thread were used for this experiment. Four water soaked pieces of dialysis tubing that were 15 cm long were also used. A small beaker for bag A was filled with a solution of 25% sucrose‚ was labeled to keep separate from the other beaker. A larger beaker was used for bags B‚ C‚ and D. It was filled with a 1% solution of sucrose‚ and was labeled for good practice. Each end of the tubes was sealed by folding and tying it tightly with one of the pieces

Results: Bag 1 had a rate of osmosis equal to 0.01 grams per minute. Bag 2 had a rate of osmosis equal to 0.0543 grams per minute. Bag 3 had a rate of osmosis equal to 0.0471 grams per minute. Bag 4 had a rate of osmosis equal to 0.0886 grams per minute. Bag 5 had a rate of osmosis equal to -0.0914 grams per minute (Figure A). Figure A: Shifting of mass in grams for each dialysis bag was measured every 5 minutes for 30 minutes. Bag 1 contained DI H2O and was submerged in DI H2O. Bags 2‚ 3‚ and

Then‚ take it out and tie off one end of the tubing to form a bag. Put an extra fold at the end‚ twist‚ and tie it with string. Rub the end of the other end between fingers until it opens. Put 15 mL of the 15% glucose/1% starch solution in the bag. Use the glucose tape and dip it in the solution. Then‚ record the color change on the tape and the bag. Tie the other end of the bag with enough space for expansion. Fill a 250-mL beaker with distilled water. Add 4 mL of Lugol’s

water across a membrane. The purpose of the study was to calculate the rate of osmosis in artificial cells containing different concentrations of sucrose and water. We studied the rate of osmosis in artificial cells by creating five different dialysis bags with different concentrations of both sucrose and water and calculating the cumulative change in weight ever 10 minutes for 90 minutes. Our results for the artificial cells showed different concentrations moved from high to low concentrations- through

BOOK IN A BAG BOOK REPORT A “Book in a Bag” is a book report contained in a brown paper or paper gift bag. The purpose of the outside of the bag is to interest a classmate to want to read your book. The inside of your bag should include items that you will be able to use to explain important parts of your book. Pick any book that is a comfortable reading level for you. (You will need to get the approval of your teacher.) Due Date: Monday‚ February 6th MATERIAL SUGGESTIONS: You will

substance from an area of high concentration to low concentration (Biological 21). With this knowledge we tried to recreate diffusion for students to understand the process. The dialysis bags represented our selectively permeable membrane with the fluid inside it‚ sucrose. How much of the substance moves from the cup to the bag quickly depends on the temperature of the substance. The class used four different temperatures to measure the rate of diffusion. I thought that the rate of diffusion would increase
