Chemical Families DVD |
|
The prize-winning CHEM STUDY video series is an extremely effective and intriguing addition to any chemistry course. Originally filmed in the 1960s these videos are still popular classics. They feature:
• Animation and time-lapse photography
• Abstract chemical processes and models brought to life
• Chemical symbols overlaid on the screen
• Results of experiments too difficult to duplicate in the classroom
Using a display of actual samples of over 70 elements, students can clearly see how elements are divided logically into families according to their chemical similarities. The program also uses experiments to illustrate that under identical conditions some gases are chemically reactive, while others are inert. It also discusses how atomic numbers have provided the key to the ordering of elements in the periodic table. Duration: 22 minutes.
