Name: Group: Date:

Aims:

After the course, students should be able to:1. Classify and identify organisms commonly found in local terrestrial habitats ,2. Measure abiotic factors in an ecosystem, 3. Distinguish interrelationships between living organisms in an ecosystem,4. Describe how abiotic factors affect living organisms,5. Record and description how human activities affect the natural environment,6. Analyze and organize data for presentation,7. Cooperate with others and work together in a scientific investigation8. Appreciate nature and respect living things.

Clothing:

1. Long-sleeved shirt and trousers for better protection against mosquito and insect bites, as well as preventing sunburn. Shorts are not recommended.

2. A pair of shoes for preventing injuries. Slippers and sandals are notrecommended.

Safety:

A. Field siteThe field sites are Tai Po Kau Garden and Tai Po Kau Outdoor Study Centre. Designate 100 m2 as the area of study in each site. Record biotic factors and abiotic factors in each study area.

B. Describing the habitatBriefing describe the nature of the two habitats, including topography, vegetation, geology, nearby land uses and other relevant information. Also draw sketch maps to show the environment.

C. Measuring abiotic factorsUse appropriate equipment to measure the following abiotic factors:a. Wind direction: Raise a piece of light nylon thread, with the aid of a compass, find out the wind direction.b. Wind speed: Use an anemometer, facing the wind direction, and measure the wind speed. Repeat measurement at different time and different locations. Take the average.c. Air temperature and humidity. Use a thermohygrometer to measure air temperature and humidity. Repeat measurement at different time and different locations. Take the average.d. Light intensity: Use a light meter to measure light intensity. Repeat measurement at different locations. Take the average.

D. Investigating each category of living organismsCount the number of species in each of the following category of living organisms. Animals can be recorded by direct observation or through their signs of activities, such as footprints, excrement, bite marks, nests, lairs and calls. Use different symbols to represent species recorded from different sites. e.g. use “X” to represent species recorded in TPK Garden, and use “O” to represent species recorded in TPK Outdoor Learning Centre. Pay attention to any dominant species.
