Educational Objectives
Students are expected to achieve the
following:
1. Preparing a plan of work for testing soil
pH.
2. Communicating
orally
through
participation in group work
3. Conducting experiment to test soil pH
by using their plan.
4. Ability to use previously acquired
background knowledge to solve the soil
problem.
5. Able to justify the range of pH for
growing healthy plant.
6. Able to make a green environment.
7. Devising and conducting experiment for
making their own fertilizers.
8. Understanding some experimental skills
in doing paper chromatography.
9. Cooperating as a member of a group.

Students’ Task
1. Through the Internet or library search
to find information and discuss with
your group members for testing the soil
pH. (Around Oct & Nov)
2. Present your proposal for testing the
soil pH (At the end of Nov)
3. Actualizing your proposal in doing
experiment for testing the soil pH
(Around Dec)
4. Take photographs of your group in doing
experiments
5. An experimental report of the
experiment in
testing the soil pH.
(Before the end of the 1st term)
6. Growing your plant
7. Find solution to improve the soil
8. Discuss with your group members in
order to devise and do an experiment
of making fertilizer and do the report
(Around Jan & Feb)
9. Use the leaves of your plant to do
paper chromatography and do the
report (Mar)
10. Regular observation and care for your
plant is needed. Take photographs of
your growing plants at regular time.
11. Present your whole process of
doing such a project (May)
