After viewing, inform students that the film was produced in 1956. What changes have been made to farming practices to promote or preserve nature's balance? Groups of students carry out research on the chemicals now used in farming, including industry regulations and known risks to humans or other organisms. Draw up a web to illustrate the importance of the food chain and effects of imbalance. Observe safety procedures used in the film, compare and contrast to today. Observe scientific methods used in the film and apply to classroom experiments.
