Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells
Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion...
Lab 5: Osmosis
Purpose: The purpose of this lab is to familiarize you with osmosis and, specifically, what happens to cells when they are exposed to solutions of differing tonicities.
Hypothesis: If we add higher concentrations of sugar to the dialysis tubing, then the net movement of coffee...
Diffusion and Osmosis Experiment
7.1 Experiment: Rate of Diffusion of Solutes
In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate, aniline blue,...
NAME: Donna Ha
TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs
INTRODUCTION: In order to fully understand the concept of this experiment, one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that...

The lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration. Five...
Osmosis and Diffusion Lab
Introduction: Osmosis occurs when different concentrations of water are separated by a selectively permeable membrane. Osmosis is the movement of water across selectively permeable membranes.
Purpose: In this experiment that we performed we will learn...
Exercise 1: Correct Use of the Scientific Method and an Experiment with
In this lab, students will:
a.) Learn how to utilize the Scientific Method to develop a testable hypothesis
b.) Generate an effective experimental design from a hypothesis
Molecules are constantly in motion due to thermal energy. Therefore, the molecules will move around and bump into each other. Because of this, molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules...
The Effect of Osmosis on Potatoes/ Diffusion of Molecules through Benedicts Test of Dialysis dubing
The focus of the lab on September 16, 2013 was Diffusion and Osmosis. Osmosis is a process in which the molecules of a solvent diffuse from an area of high concentration...
DESIGN ASPECT 1: Defining the Problem and Selecting Variables
CELLS are the basic unit of structure in all organisms and the smallest unit of life. All living things are made of cells. Multicellular organisms (humans) are composed of many cells. Unicellular organisms (bacteria) are composed of on...
State the hypothesis you will be testing in your investigation
As the concentration of sucrose solution increases, the mass of potato pieces decreases.
Explain the hypothesis using scientific ideas.
My hypothesis is based on osmosis. In the process of Osmosis, water moves across a partially perme...

Lab 1: Circadian Rhythms
A. Activity #1: Homeostasis
1. Homeostasis: the body's ability to maintain itself in a steady (but not constant) state.
2. Negative Feedback: mechanisms that respond to reverse the change when a variable is outside of its set range.
The purpose of undergoing the lab was to analyze the process of diffusion through semisolids. Along with investigating the course of diffusion, focusing on the path of osmosis was additionally significant. In order to comprehend these vital developments, a definition is necessary. In the structure o...
