TeachNet Grant: Vlogging in Chemistry
Kevin Jackson

Newcomers High School
28-01 41st Ave
Long Island City, NY 11101

Grade Level: 10-12 Chemistry, Media, Technology, ESL
About the Grant:

The Vlogging in Chemistry Unit focuses on the balancing of redox reactions in chemistry.  The students will create a video blog entry that will explain the procedure to balance a reaction using oxidation and reduction half reactions.

How it Works - After learning about oxidation and reduction in class, students will write a "script" that explains all the steps needed to balance a given reaction using oxidation and reduction half reactions.  Afterwards, the students will prepare a presentation on a laptop that can be recorded using a desktop recording software like Jing or Smartboard recorder.  The presentation will be placed on a class blog where other students can view the video and comment on the procedure chosen by the team.  Finally, the video blog entry can be used as review of the topic later in the semester.

Final Project/Product - Students will write the script that shows the procedure that answers the question.  They will then post the videos on a blog where other students can leave comments.  The focus of the video is not to answer to the question but describe the steps taken to find the answer.

How This Grant was Adapted:

Overall Value - The unit crosses multiple curricula and focuses on the students understanding of the steps to find the correct answer instead of the answer itself.  The unit has ESL students collaborating on a written script and speaking on a recorded presentation on a key element of the Chemistry curriculum.  Using the recording software eliminates anxiety of performing in front of an audience because only the students voice will be heard.  They then can comment on the work of their peers and use the videos in the future for review.

Tips for the Teacher -
If you have a blog already with your class check that the server allows videos to be posted.  Several hosting sites charge additional fees for video posting.  A word wall is useful for this unit because it will emphasis the vocabulary that the students will need for their videos.  This unit used the smartboard recorder software to make our videos.  If a smartboard is not available the students can still use the program to create their presentations.  Other recorder software, like Jing (link below), is available that will record the desktop and will allow students to use programs like powerpoint or Microsoft word for their presentations.

Check with your school to find their policy on publishing student work on the internet.  Most require a permission form or release.

Procedure 2:  Add aluminum foil and stir with glass rod
Procedure 3:  Walk around the room and have students observe the beaker.  Ask them to feel the beaker and try to figure out what happened.
Procedure 4:  Allow students to discuss their ideas about the reaction
Procedure 5:  Introduce the reaction as a single replacement reaction
Procedure 6:  Write the reaction on the board or a transparency.  Al + CuCl2 à AlCl3 + Cu
Procedure 7: Ask them to describe what is different about the Aluminum and Copper on each side
Procedure 8: Explain the changes in oxidation number state Al goes from 0 to +3 as loses 3 electrons, Cu goes from +2 to 0 as it gains
Procedure 9:  Review the rules of assigning oxidation numbers
Procedure 10:  Explain the procedure for finding the unknown oxidation number in a compound and ion.
Procedure 11:  Show different reactions and have students assign oxidation numbers to each element.  Select many oxidation and reduction reactions
Procedure 12:  For each reaction have students compare the oxidation states of the same element on each side of the reaction.  Ask them to describe how the oxidation states change
Procedure 13:  Define oxidation and reduction for students  have them go back to each of the reactions and identify which elements are oxidized and which are reduced.

Homework -  Practice problems that require students to assign oxidation numbers and then identify oxidation or reduction

Assessment - Select various reactions from the acids and metals unit and have select various students to identify oxidation states and list what rule is used.  Also have them identify oxidizing agents and reducing agents
