 The
Growing Process of Grapes
Natural Science lesson plan from Vanita Coetzee, Ikanyegeng
School
Critical Outcome 1:
- COMMUNICATE EFFECTIVELY USING VISUAL MATHEMATICAL AND/OR
LANGUAGE SKILLS IN THE MODE OF ORAL AND/OR WRITTEN RESENTATIONS
Critical Outcome 2:
- IDENTIFY AND SOLVE PROBLEMS BY USING CREATIVE AND CRITICAL
THINKING
Specific Outcome:
- DEMONSTRATE AN UNDERSTANDING OF HOW SCIENTIFIC KNOWLEDGE
AND SKILLS CONTRIBUTE TO THE MANAGEMENT, DEVELOPMENT AND
UTILISATION OF NATURAL AND OTHER RESOURCES.
AT THE END OF THE LESSON LEARNERS MUST BE ABLE TO:
- Name the properties of sand and clay soil.
- Develop an experiment to determine what type of soil a
given sample is.
- Communicate their experiments by means of a pamphlet.
The Growing Process of Grapes: Soil Fertility
Lesson Plan
Soil for grapes:
What is soil?
Influence on wine quality
Types of soil:
Sand, Clay
SOILS FOR GRAPES
Soil consists of:
- Weathered particles that together with:
- Provides a medium in which plants can grow
Vines are able to adapt themselves to a very wide range of
soil types.
INFLUENCE OF SOIL TYPES ON WINE QUALITY
The influence of specific soil types on the quality of the
wine is disputed.
- FRANCE Attributes great value to lime content
- ITALY No special value to lime content
- GERMANY Attributes great value to slate-stone
The finest fruits are often cultivated where the soil composition
is large, grained and well drained.
Grapevines generally produce their finest fruits in calcareous,
or slate soils. Local vineyard farmers attribute great importance
to the lime content of their soil.
TYPES OF SOIL
1. SANDY SOIL
- is well aerated
- easy to cultivate
- well drained
- is a warm soil
- has low water retaining capacity
2. CLAY SOIL
- usually drains slowly
- ap to become waterlogged
- difficult to cultivate
- reains water and plant nutrients well

Assessment
Previously a lot of farmers did not take into consideration
the type of soil when they decide to plant vineyards. Nowadays
farming is seen as both a science and a business.
The local farmers cannot afford to send away soil samples
for analyses as it is very expensive.
You are appointed as a consultant by the local co-operation.
Your main task is to help the new upcoming farmers.
Use Microsoft Publisher to design a pamphlet (including text
and images) which includes possible experiments, that the
farmers can conduct themselves, to help the farmer decide
if the ground on his farm is suitable for planting vineyards.
CONCLUSION
- 10 Years after democracy more people has the privilege
to own their own land.
- With each privilege goes together a responsibility.
- Farmers have to run their farms according to their business
plans in order to make it sustainable.
- In order to develop their natural resources, farmers need
to apply scientific knowledge and skills when making decisions.
