Introduction

This is an interactive science activity (ISA) that uses the the image magnifier iDevice to explore the structure of bacteria cells. The iDevice is part of the e-learning XHTML editor called eXe which was created by the eXe team at the University of Auckland.

You may have heard of E. Coli (image above) which is short for Escherichia coli -- a bacteria which has strains that cause severe cramps and diarrhea. It can be found in contaminated drinking water, and food. In the fall of 2006, there was a huge recall of Spinach which affected at least 21 US states and Canada due to E. coli contamination.

There are also strains of bacteria that are beneficial. For example, biological water purification is performed to decompose organic compounds. The microrganisms, responsible for the decomposition are mainly bacteria. Bacteria are everywhere! Interested in learning more about the cell stuctures of harmful and beneficial bacteria?

Overview

The Bacterial Cell Structure interactive science activity consists of: An exploration of the a bacteria cell. A short multichoice question to help you determine which of the main activities you should try. The main activity where you will identify several labeled intracellular structures by examining an image under a magnifying glass. It consists of: Identification of 5 structures. Defining 2 of the structure's functions.

How long will it take?
These activities should take you between 20 and 30 minutes to complete. If you are far from completion after 20 minutes you should contact your teacher.
