Osmosis Laboratory Report
Albuquerque High School
Beginning Steps (1)
For this experiment that we are doing we have been observing the process and effects of Osmosis. What is Osmosis you ask? Well Osmosis is when water moves to areas of high concentration. Osmosis takes place in many things including: Animals, and Plants but for now let’s just focus on osmosis in plants. So we decided to ask the question: How do different concentrations of salt (NaCl) affect osmosis in plant cells? The purpose of this experiment was to observe what happens to in plant cell when we add add salt to them.
As we increase or decrease the salt concentration of solute (salt) in the environment then the rate of osmosis and mass of the core deionized water.
Knife or Razor blade
Beakers, baby food jars, or plastic cups
Salt solutions (1%, 3%, 5%)
Deionized H2O (water)
Microscope slide and coverslip
Salt Solution (5%)
This is a detailed step-by-step description of the experiment. Recall that anyone should be able to replicate your experiment based on your procedure, do not leave steps up to interpretation.
Data and Analysis:
Here you provide the evidence of the experiment (the data you collected). Data can be collected using tables while relationships (analysis) can be done by converting such tables into graphs (excel is a great tool for this). Make sure you also include all your calculation in this section as such calculations provide additional evidence to support your conclusions.
