Project Handout/Rubric


"Compounds Explained"

Background:  In the second trimester of Ms. Todd's Science 7 class,  65 seventh grade students learned about atomic structure, periodicity, ionic and covalent bonding, polar and non-polar covalent bonding, and ions.  We created projects called "Compounds Explained", where every student received a compound and then researched it, scripted a screencast, and then created the screencast about the bonding of the compound as well as how it was used.

Purpose:  The purpose of the project was to have students gain a deeper understanding about chemical bonding by having them create a screencast, or short video tutorial, about how their compound bonded and how it was used in real life.  By creating a tutorial such as this for formative and summative assessment, there is evidence that it helps comprehension and analytical thinking about abstract concepts such as atomic structure and function.

Project Handout/Rubric:  The following document was used as a class resources.  It includes the rubric.: "Compounds Explained".

Tools:  To create a screencast on your mac or PC you have multiple options for software. You can use online resources or stand alone software on your PC.

Mac Options for Stand Alone Software: IShowU (very inexpensive) or Snapz Pro X for use along with the free iMovie or a higher end video editor like Final Cut Pro

PC Options for Stand Alone Software: the killer application of the screencast world- Camtasia, Camstudio (Open source and Free), or Windows Media Encoder (Free with Win OSs) for use for Windows Movie Maker or a higher end video editor like Adobe Premiere Elements).

Mac and PC options that are Internet based: Screencast-o-Matic

A new free application at the moment form the makers of Camtasia, and it is cross platform: Jing!
