Would you ban Dihydrogen Monoxide (DHMO)?
Description:

Students evaluate two very real-looking websites on the dangers of dihydrogen monoxide as part of an assignment to take a position on whether or not dihydrogen monoxide should be banned as a dangerous substance. Subsequent comparison to other sources reveals dihydrogen monoxide as an obscure name for water.

    Procedures:

    Introduction (5 minutes):  LMS will introduce the lesson.  Keep the introduction short so as not to tip off the students to the actual outcome of the lesson.


    1.      Students will be using a new buILder tool similar to a webquest to do a mini research lesson.


    2.      Direct student to website http://www.informationliteracy.org/builder/builder.php?primaryid=255


    3.      Explain how the buILder works.  Ex.  Need to go to left bar and proceed through the steps in order.








     (methods, media, materials)Direct Instruction, hands on activity, computers, worksheet http://www.informationliteracy.org/builder/builder.php?primaryid=255



     


     


    Body (30 minutes): Have students form pairs and begin the lesson at the home page.



    1. Have them read through Information challenge and Information task and then stop.

    2. Hand out photocopy of worksheet (available on the buILder site) or put questions on board or overhead for students to answer on their own paper. They must prove their sources are reliable so the mayor will listen to their advice.  Ask the students to decide if they want to ban DHMO. Explain the 5 components they will be looking for on each webpage.  Also explain not all of these items may be found on each page.


          D ate published or last updated


          URL of website


          Pop up ads on the webpage


          E –mail address to contact someone


          Who Designed and created the website




    They may begin doing the tasks.  Allow about 5 minutes for each website. Reiterate that it would be beneficial if they read the text on the websites.



    1. After students complete the worksheet ask for a show of hands on their positions on whether or not to ban DHMO.   Some students will still not realize it is water. Play NPR commentator Robert Siegel's interview with the site's creator,
      Professor Tom Way

      ,       http://www.npr.org/templates/story/story.php?storyId=1791960 (approximately 4 minutes).

    2. Discuss their reactions to dihydrogen monoxide.

    3. After everyone realizes it is water.  Demonstrate with help of Powerpoint what features of the websites should have clued them to the fact these were unreliable sites.
