These weekly nature bulletins, for instance, are effectively used by most teachers in classroom work and for reference. On the basis of one copy for each teacher in the elementary grades and one for each biology teacher, they are mailed to every parochial school and every suburban and rural school in Cook County. There is no charge. A program ordinarily begins with a brief talk on how to use and enjoy the preserves, followed by about 22 minutes of superb movies, in color with sound, on wildlife or natural history subjects suitable for the grade levels of the pupils. During the remainder of the period the naturalist answer questions from the audience.
Appropriate programs are available for high school assemblies.
Since there are over 1,022,374 pupils enrolled in the public schools of Cook County, it is obviously impossible for us to conduct field trips for, lecture to, or otherwise deal with individual classes. That is a responsible function of the schools. However, many teachers do not feel competent to teach natural science and are understandably reluctant to attempt field trips. There is increasing demand for courses which will train them to do so. This series is repeated again in the fall.
