Rationale / need of Practical Work
• The science is highly complex and abstract
• For hands on experiential learning
• Concrete to abstract learning
• Verification of Theory
• To appreciate the spirit and methods of
science
• Develops various important scientific skills
• Practical work is intrinsically interesting to
students

What is Integrated Science Laboratory?
• A Science laboratory which brings
closure of
knowledge of various subjects
• Integration of physical structure of lab
i.e.;
• Having lab items of all subjects in one
lab

Why Integrated Science Laboratory?
• Modern science is becoming interdisciplinary
• To understand how basic sciences overlap
each other
• To study the concept as whole
• Realise how all things work together to
sustain life
• Less space and money it can be constructed

Integrated experiment on “Balanced diet”
• Analysis of food stuffs for various nutrients - Chemistry
• Source & importance of nutrients for human beings - Biology
• Expressing required quantity of nutrients in mg/g/kg - Physics
• Collection analysis and interpretation of data - Statistical
• Computational methods of data analysis - Computer Sci.
(An example)

Tribulation in Laboratory Work
• Dissection has been banned
• Lack of enough fund / facility
• High strength of students
• More time consuming
• More expensive

Alternatives to Tribulation Laboratory Work
• Computer simulations of dissection & experiments
• Interactive computer for problem-solving exercises
• Animated film CDs and DVDs
• Internet pictures/videos
• Documentary film CDs & DVDs
• No-cost / home-made experiments (Picture- 2 & 3)
• Outdoor laboratory - garden, zoo, aquarium, lake etc.

Evaluation of practical work in the
form of CCE (Factors to be considered)
• Planning and design
• Performance
• Analysis and interpretation
• Application

Conclusion
I realise that concept of science has to be
learned as whole (integrated). Holistic
experiments in such Integrated Science
laboratory can satisfy the need of all
science subjects and contribute as
constructive pedagogy at school level.
