THE WEB OF LIFE SERIES 



Color Sound Encyclopaedia Britannica Films 



2 parts; Rental Sale 



30 minutes complete 



Today evolution is considered an on-going process rather than a 

 static accomplished set of activities. This film, in reel one, empha- 

 sizes this point as it shows that unless living things can adapt them- 

 selves to constant change, they must perish. This adaptation results 

 in the many forms of life which exist and are constantly developing. 

 The balance of life within which an organism exists is shown to be 

 very delicate and it is understood to be applicable to all forms of 

 living things, although plant life is used for emphasis in this film. 



Reel two brings to our attention the extent of damage which 

 can result from man's interference with the balance of nature. Some 

 of the problems, with some ideas of solving them, are introduced, 

 such as poor forest utilization, overgrazing, indiscriminate slaughter 

 of predators. The film also makes us aware of possible problems 

 resulting from our population explosion. 



WHAT IS ECOLOGY? 



Color Sound Encyclopaedia Britannica Films 



11 minutes Rental Sale 



Since ecology, if understood, leads to an appreciation of conser- 

 vation, this is an important and fundamental film. In advance, chil- 

 dren should understand all the terms which are used, such as 

 scavengers, decomposers, community, aggregation, biome, etc. 



With this knowledge they can be directed to look for how a lack 

 of knowledge caused the catastrophes depicted loss of a farm, 

 floods, dust storms, etc. They can then understand how a knowledge 

 of ecology could have prevented the tragedies. They may even be 

 able to supply the exact knowledge in some of the cases. 



Certain concepts such as change, community interaction, the sun 

 as the prime source of energy are particularly well explained.
