Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

Marisela Andrade The Effects of Salt Water on Gummy Bears Facilitated diffusion depends on passive transport. Molecules cross cell membrane by diffusion. A type of diffusion is osmosis. If no energy is input into the system during diffusion‚ the molecules will reach a state of equilibrium. The purpose of this experiment was to study why the death occurred among those who drank salt water. Two blue gummy bears had a height of 2 centimeters each. The mass of these gummy bears together were

The goal of this experiment include the investigation of various acid/base indicators‚ calculating the change of pH with concentration‚ change of pH due to the addition of salt and different between strong and weak acids/bases. Safety and Disposal: Use extreme caution when handling concentrated acids and bases. Dispose of all

The Twin Experiments was conducted by Josef Mengele‚ during World War 2 in Auschwitz. Dr. Mengle was a medical researcher who was fascinated with twins in specific. From the three thousand children that would be pulled from the masses of people upon arriving only about 200 survived. Age didn’t matter‚ yet most were children‚ and if they were really young their mother would be allowed to stay with them. The twins recieved "special" treatmeant as they were allowed to keep their hair and clothes. A

Hawthorne Experiment. Advantages: During the experiment the performance of the group has increased (Not because of improving conditions‚ but because of the communication and collaboration) Disadvantages: there were personnel changes‚ that is the workers hostile watching the situation changed for those who would like to work in such conditions (that is attended only those workers who are more willing‚ not all workers) Conclusion: This experiment showed that workers are willing to actively

Describe the physiological approach to the study of the mind. Explain how Donders experiment can be repeated in a modern laboratory using the physiological approach to the study of the mind Donder’s work attempts to describe the processes going on in the mind‚ by analyzing cognitive activity into separate stages. Until Donder’s work‚ many scientists had assumed that the mental operations involved in responding to a stimulus occurred instantaneously. Donder was particularly interested in "timing
