The masses were relatively the same the difference have could been from the amount of liquid that was placed inside of each of the bags. The second experiment with 5% Ovalbumin in the bag and 1 M sucrose in the beaker had almost exactly the same results. The masses were relatively the same the difference could have been from the amount of liquid that was placed inside the bag. The substances that entered the bag for the

important event in the book is when the police go to the dumpsite looking for the bag. This event is important because it make Raphael‚ Gardo and Rat curious‚ it also makes the police angry because they can’t find the bag. The last reason is that it’s a catalyst to other events in the story. The story is about three boys in a third world country who earn a living by picking through rubbish. One day they find a bag‚ the contents of it put them into a terrifying adventure‚ fighting against corruption

As we become more technologically advanced‚ we produce materials that can withstand extreme temperatures‚ are durable and easy to use. Plastic bags‚ synthetics‚ plastic bottles‚ tin cans‚ and computer hardware- these are some of the things that make life easy for us. But what we forget is that these advanced products do not break down naturally. Plastic bags are difficult and costly to recycle and most end up on landfill sites where they take around 300 years to photo degrade. They break down into

Bag #1’s solution was hypotonic compared to the solution of beaker #2. Bag #2’s solution was also hypotonic compared to the solution of beaker #2. Bag #3’s solution was isotonic compared to the solution of beaker #2 and Bag #4’s solution was hypertonic compared to the solution of beaker #1. 2. Which bag increased the most in volume? Why?

2013 Methods and Materials (Bread Mold Lab) Block 1 The materials needed to conduct this experiment are six small squares of bread‚ a container of milk‚ four small Ziploc bags‚ a thermometer‚ a phone to record data and a heat lamp. The container of milk will be used for residue on the inside of two of the plastic bags. The heat lamp will be used to generate heat onto the bread towards the possibility of mold. The thermometer is used to measure the heat that the heat lamp is producing; this is

higher percentage of popped kernels when frozen. This is relevant because most people would like to get the best value out of items they purchased and this may demonstrate one way to do that. I will be freezing multiple bags of popcorn and then popping both frozen and unfrozen bags in the microwave. Finally I will count the popped and unpopped kernels to determine the percentages for both variables and if there is a difference. Literature Review Through my research I did not find any other experiments

Osmosis Rates in Artificial Cells Daniel George Department of Biology Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 georged@mail.gvsu.edu Abstract The lab for this paper was conducted for the topic of osmosis‚ the movement of water from high to low concentration. Five artificial cells were created‚ each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic‚ hypotonic‚ or isotonic solutions for a period of 90

achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put them into beakers of distilled water to see how the color changed in the bag/beaker. The result was that the more sucrose in the bag‚ the greater the final mass. Introduction: The reasons for doing this lab are so that we can learn about osmosis with a model similar to a cell and so that we can have a better understanding of the process and nature
