RV review We are almost through another school year with so much left to cover. There is still time to order films, filmstrips, etc. and use them as a review or as another teaching technique. Sometimes we find ourselves continuing to do what we have for years because it is easier, although many of our colleagues have used A-V materials very successfully. Edna Hudson from Cedar Ridge High School has two reviews to share with us.

to show the connection between the chemical language and the chemical substance. The weakest part of the series, in my opinion, is the last filmstrip which balances rather difficult equations. By this time, my students have heard the explanation that follows the correct answer too many times. I have, however, found it very helpful to use selected problems from the set as a basis of a "seat-work" oractice session. This filmstrip set comes with a complete teacher guide, including script. A reference chart which can be copied for student use lists the elements, their symbols, and some common ions and their charees. Also included are an excellent one-sheet summary of astep-by-step method of balancing eauations and ample practice problems (with answers) for each part of the seiies: EDNAHUDSON Cedar Ridge High School Old Bridge.

Man and Molecules (over 200 individual titles) Time: Two fifteen-minute programs Format: Audio-cassettes Price: $7.001each single cassette $6.00/each 8 to 19 cassettes $4.001each any 20 or more Supplier: American Chemical Society 1155 Sixteenth St., N.W. Washington, D.C. 20036 Dept. M and M
The American Chemical Society produces audio cassettes on a variety of scientific topics in their series "Man and Molecules." Each of the cassettes contains two 15-min programs. I found them useful as a n out-of-class assienment for students on a current topic. The cost is $7 for a single cassette; $6 for 8-19 cassettes; and $4 for 20 or more. Since there are too many programs to list here, I suggest you write directly to. the American Chemical Societv for their brochure describing all of the programs. Another way to receive them would he on a yearly subscription where you automatically receive cassettes bi-weekly on current scientific topics. The cost here is $75 for twenty, or $90 for 25 cassettes. You do not, however, have a choice of topics which include the fields of biology, environmental science, etc. Some programs of interest to the chemistry teacher would be: "Synthetic Metals" narrated by Dr. Alan MacDiamid naired with "Catalvsis: Coal to Chemicals" narrated bv Dr. M. Albert ~annice."Discovery of Element 106" by DR. dlenn T. Seahore and Albert Ghiorso aired with "Suoerheaw Elements" Dr. Edward ~nder'.
