This document discusses the laboratory method of teaching science. The laboratory method involves students deriving scientific laws and principles through hands-on experimentation. There are two major types of laboratory methods: situations where students work informally in small groups with shared equipment, and demonstrations performed by teachers. The goals of laboratory work are to teach observational skills, scientific inquiry methods, and problem solving. Safety is emphasized, and advantages include developing skills like observation, reasoning, and applying the scientific method, while disadvantages include the time and cost inefficiency.

1. Principles of Teaching
The Laboratory Method

2. What is
The Laboratory
Method?

3. Laboratory Teaching Methods
This methods is one of the important
methods of teaching science and it forms an
integral part of effective science teaching.
Under this methods, teachers encourages the
students to derive various scientific laws and
principle on their own by getting personally
involved in the experiment work.

4. • Scientific Method is define as the principles
and procedures for the systematic pursuit of
knowledge involving the recognition and
formulation of problem, the collection of
data through observation and experiment,
and the formulation and testing of
hypothesis.

5. 2 Major Types of Laboratory Methods
1. Situation where students work in the
laboratory- In this situation student’s work
informally in pairs or groups where
equipment cannot go around all students
individually.

6. 2 Major Types of Laboratory Methods
2. Demonstration- is a process of presenting or
establishing facts or principles. It is a
procedure of doing or performing something
in the presence of others or either as a
means of showing them how to do it or
illustrating a principle.

7. MAJOR GOALS OF LABORATORY
WORKS
Teaching Manuals and Observational
skills relevant to the subject
Improving understanding methods of
scientific inquiry
Developing problem solving and doing
by self skills.

8. CORRECT METHODS OF TEACHING IN
LABORATORY
1. Self Preparation
2. Right Explanation
3. Starting Experiments
4. Handling instruments
5. Explaining observations
6. Writing reports
7. Lab safety

9. Advantages of Laboratory Method
1. Students learn by doing and come in contact
with raw data or materials in teaching
learning process.
2. Develops the power of observation and
reasoning.
3.Develops the scientific attitudes
4. Gives an understanding of what research is
and how to apply the scientific method

10. Advantages of Laboratory Method
5. Gives training in organizing data gathered
from real materials object and how these
objects are manipulated to attain the
objectives.
6. Since students come in contact with real life
situations, it can be a preparation for solving
real life problems

11. Disadvantages of Laboratory Method
1. Uneconomical way of learning in time and
material.
2. Does not give much training in verbal
expression and when the same equipment
is used most of the time, its use becomes
mechanical i.e., used without much
thinking anymore

12. SOME LABORATORY TEACHING
METHODS
Students learn by their own efforts.
Demonstration methods
Slide Booklets show process -complex
procedure, and complicated apparatus
Tape booklets for methods of calculation
Wall Charts
Video Recording
Computer Simulate

13. Laboratory Safety Tips
Think safety first
Know emergency responses
Know what your working with
Use the smallest possible amounts
Follow all safety procedures
Report dangerous activity or situations
Store and handle hazardous materials safety
If you don’t know ASK!

tomorrow. Learn as if you were
to live forever.”
