BIOLOGY PRACTICAL ACTIVITIES

  1. Ecology is best studied outdoors.
  2. Students identify a habitat within or near the school compound, e.g. a flower bed.
  3. The quadrat method is used.
  4. Observation and recording of the various animals as well as their feeding habits is done.
  5. Birds that feed on the plants or arthropods in the area studied are noted through observation of habitat at various times of the day.
  6. Food chains are constructed e.g green plants ~ caterpillar ~ lizard and many others involving all organisms in the area.
  7. The numbers of animals in 1 m2 is counted directly or estimated e.g small arthropods like black ants.
  8. The number of plants is easily counted and recorded and ratio of consumers to producers calculated.
  9. It will be noted that in terms of numbers where invertebrates are involved, there are very many consumers of one plant.
  10. Several other quadrats are established and studied and averages calculated.
