2. Identify factors affecting salinity of sea water.

3. Explain reasons for variation in salinity in different seas.

4. Locate areas of high and low salinity on the map.

5. Analyze the importance of salinity in marine environment.

Process Objectives

Students will develop:

1. Inquiry and questioning skills.

2. Observation and experimentation ability.

3. Logical thinking and reasoning.

4. Problem-solving skills.

5. Scientific attitude and curiosity.

Previous Knowledge

Students already know:

• Oceans and seas

• Presence of salt in sea water

• Evaporation and rainfall

Syntax	Classroom Interaction	Pupil Activity
Phase 1 — Presenting the Problem Situation	Teacher shows two containers of water: ·         One labeled Arabian Sea ·         One labeled Baltic Sea Teacher asks students to taste a drop (or imagine through explanation) and asks: Why does sea water taste salty? Is the saltiness the same everywhere? Why do some seas have more salt than others? Teacher shows world map highlighting different seas.	Students observe and express curiosity. Students realize there is variation in salinity.
Phase 2 — Data Gathering (Verification)	Teacher asks students to ask yes/no questions to collect information. Teacher responds only with “Yes”, “No”, or “Partly”.	Student Questions (Examples) Does evaporation affect salinity? Does rainfall reduce salinity? Do rivers affect sea water salinity? Does temperature influence salinity? Teacher answers accordingly. Students collect basic facts.
Phase 3 — Data Gathering (Experimentation)	Teacher conducts a simple demonstration: ·         Two bowls of water ·         Add salt to one ·         Heat one bowl slightly to show evaporation effect Teacher asks students to predict changes. Teacher provides maps showing rainfall distribution and river inflow.	Students observe demonstration. Students relate evaporation, rainfall, and river inflow to salinity differences.
Phase 4 — Organizing and Formulating Explanation	Teacher asks students: Why is salinity higher in some seas? Why is it lower near river mouths? Teacher guides students to identify factors: ·         Evaporation ·         Rainfall ·         River inflow ·         Temperature ·         Enclosed seas	Students formulate explanation: High evaporation → High salinity Heavy rainfall → Low salinity River water → Reduced salinity Students conclude that salinity varies due to climatic and geographical factors.
Phase 5 — Analysis of Inquiry Process	Teacher asks students to reflect: What steps did we follow? How did we find the reasons? Which factor is most important? Teacher summarizes inquiry steps.	Students explain learning process and reasoning.

Blackboard Summary

Salinity = Amount of salt in sea water

Factors affecting salinity:

• Evaporation

• Rainfall

• River inflow

• Temperature

• Location of seas

High salinity → Red Sea
Low salinity → Baltic Sea

Social System

• Teacher acts as facilitator.

• Students actively ask questions and investigate.

• Cooperative and interactive classroom environment.

Principles of Reaction

Teacher:

• Encourages questioning

• Accepts student ideas

• Provides hints instead of answers

• Reinforces correct reasoning

• Guides inquiry process

Support System

• Map and globe

• Water samples

• Salt and containers

• Charts and diagrams

• Worksheets

Instructional Effects

Students understand:

• Meaning of salinity

• Factors affecting salinity

• Reasons for variation in sea water salinity

Nurturant Effects

Students develop:

• Curiosity

• Scientific thinking

• Inquiry skills

• Confidence

• Logical reasoning

Evaluation

1. What is salinity?

2. Name two factors affecting salinity.

3. Why is salinity higher in enclosed seas?

4. Which sea has low salinity?

Home Assignment

• Locate areas of high and low salinity on world map.
