This lesson plan outlines an activity to teach students about primary, secondary, and complementary colors. The teacher will divide students into groups and have them mix water colors to discover: 1) Primary colors are blue, green, and red, which when combined make white. 2) Secondary colors are formed by mixing any two primary colors, such as yellow from green and red. 3) Complementary colors are pairs that make white when mixed with a primary, like green and magenta. Through hands-on experimentation, students will develop an understanding of the relationships between different colors.

CURRICULAR STATEMENT
Through experimentation, observation and discussion, students develop
understanding about primary, secondary and complementary colours.
CONTENT ANALYSIS
TERMS: Primary colours, secondary colours, complementary colours
FACTS: 1. There are seven colours in rainbow.
2. White colour is a combination of seven colours.
3. Prism is used to scatter the light.
4. Blue, green and red are primary colours.
5. On combining primary colours, we get other colours.
CONCEPT: 1. The colours that were combined to get white colour are called primary colours.
2. The colours formed by the combination of any two primary colours are called
secondary colours.
3. The pair of colours combined with a primary colour to get white light are called
complementary colours.
LEARNING OUTCOME
The pupil,
Develops remembering about above terms, facts, concept
Develops an understanding about colours
Applies acquired knowledge in new situation
Develops process skills such as observation, inference making etc.
Analyze various components of colours

2. Develops ability to evaluate acquired concepts
Develops components of creativity
Develops interest in Physics
Develops scientific attitude
PRE-REQUISITES
Students know about colours
TEACHING-LEARNING RESOURCES
Water colour, brushes, water, activity cards, etc.
Classroom interaction procedure
Introduction
Teacher asks: “How many of you like to colour pictures?”
Teacher says “Today we are going to play with colours”
Presentation
Activity-1
Teacher groups the class into four groups and give packets of water colour
to each group. And asks them to mix any three colours so that they get
white colour as a result
Teacher asks “When did you have white colour?”
Consolidation
The colours that were combined to get white colours are called primary
colours.
Activity-2
Teacher asks students of each group to mix the primary colours with two
colours at a time and record the resulting colours in activity card provided.
Consolidation
The colours formed by the combination of any two primary colours are
called secondary colours.
Pupil response
Students raise their hands
Students actively participate
and record the findings.
By mixing blue, green and red
colours
Students attained the concept
Students fill activity card.
Colours mixed Colours obtained
Green + red Yellow
Green + blue Cyan
Red + blue Magenta
Students attained the
concept

3. Activity-3
Teacher asks students to make white colour by mixing any one primary
colour and secondary colour to form white colour.
Teacher asks: “Which are the combination of colours which give white
colour?”
Consolidation
The pair of colours combined with a primary colour to get white light are
called complementary colours.
Teacher consolidates the class by revising the topic once again.
Students actively combine
colours and finds result.
Students replied green and
magenta, red and cyan, blue
and yellow.
Students attained the concept.
FORMATIVE EVALUATION
Review
