Bacteria+and+Viruses

=Title: Aren't Bacteria and Viruses the Same Thing? = =The Big Idea: Bacteria and Viruses = =Objectives: __Students will be able to:__ = =Standards:=
 * 1) == Describe a bacterium and its cell structure. ==
 * 2) == Describe a virus and how it functions. ==
 * 3) == Use technology to demonstrate the differences between bacteria and viruses. ==

Science: Life Science- 7th Grade Standard 2 and 3 (cells)
=Background Knowledge:= == I think that among the general public, the thought is that bacteria and viruses are terms that can be used interchangeably. Students need to recognize that there is a difference, which is why treatment for them is different. For this lesson students need to know: == =Materials:=
 * 1) == Characteristics of living things: growth and development, metabolism, made of cells, reproduce, and react to the environment ==
 * 2) == Cells are surrounded by a membrane ==
 * 3) == Cells have organelles and these organelles have specific jobs that are interconnected. ==

=Procedure:= > > == ==
 * == Students are going to need to research some information on the following topics. I will assign each group of two a certain topic. Some groups will have the same topic, but they might come across different information to share with the class. It will be the job of the groups to share information with the rest of the class. To find this information, students can use the internet, the IPad, encyclopedias, books, etc. I will moderate the information, so that students have accurate material. As a class, we will discuss these topics. ==
 * == What is a bacterium ? ==
 * == Structure- single celled, cell membrane ==
 * == Examples- E. coli, Salmonella ==
 * == Impact on humans- they are everywhere, only a small fraction are pathogens for humans ==
 * == Antibiotics- help to fight bacterial infections ==
 * == What is a virus ? ==
 * == Structure- genetic material, protein coat, lipids ==
 * == Examples- measles, mumps, HIV ==
 * == Impact on humans- pathogens ==
 * == Antiviral Drugs- help to fight viral infections, difficult to make ==
 * == After having students share, we will watch two short videos from discovery streaming about bacteria and viruses. The videos recaps the information that the students learned about from their presentations. The videos are only available if you have an account with them. The two videos are: ==
 * == Bacteria Video - selected pieces of the video should be shown, probably not the whole thing at one time. ==
 * == Virus Video -select the virus overview and the vaccine piece ==
 * == Students will be asked to ﻿make a "blabber" to recap the differences in viruses and bacteria. Students can choose to make a blabber with two pictures (one bacteria and one virus) or they can choose one or the other. I will be sure that there will be an equal number of each. I want to be sure that both aspects are covered. Students will need to find some pictures off of the internet of bacteria and viruses for their blabber. They can use picsforlearning or clipart. They will import the picture into blabberize.com, record their summary, and present what they have made to the class. ==
 * == Finally students can use __Gene Labs Lite__, __Immuno HD__ , or __Virulent__ to play around with viruses and bacteria. These are game apps on the IPad that try to demonstrate some aspects of what bacteria and viruses are and how they behave. ==

Reflection:

 * 1) == Were students able to gather the information about bacteria and viruses on their own, and was it complete? ==
 * 2) == How could I set up stations with this type of a lesson? ==
 * 3) == How long will it take for a class set of "blabbers" to be made? ==
 * 4) == Where might I find a more engaging video- make one? ==
