Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

The Effect of Concentration Gradient on Osmosis Abstract: Osmosis is the passive movement of water from an area of higher concentration to an area of lower concentration‚ usually across a membrane (Thorpe 2013). Tonicity is the ability of a solution surrounding a cell to gain or lose water (Reece 2011). There are many factors that affect the rate of osmosis. These include temperature‚ surface area‚ difference in water potential‚ pressure‚ light and dark and most importantly what we will be talking

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

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no
