Recently I found several free resources on how to make Winogradsky Columns and I want to pass the information on to you for FREE!!!
A Winogradsky Column is a simple and inexpensive experiment that ANY student can do, regardless of age or skill. It is a FOOL PROOF EXPERIMENT.
A Winogradsky Column is simply: (Wet sediment + Nutrients + Water) all inside a glass jar, and after a few weeks the jar will become a home to several different microbes. The colonies are colorful and they change overtime. Your download of this product will explain all of the "how" and "why" information that you need to know.
This is an excellent experiment to do if you are looking to help your students make observations and inferences. It will also supply a LOT of curiosity from students of every age.
I am working on creating valuable and effective products, so please let me know how I am doing by rating this resource.
