Lesson
Plan: Newton’s Color Disc
Class Level: VII
Curriculum Links: Science Class VII Chapter 15
Method: Project
Based learning
Author: Mrs. Shephali Bose,
TGT Science, KV Bhandup
OBJECTIVES:
1.
Student
will learn that visible light is made of seven colours.
2.
Students
comprehend what are primary colors and that all other colors are a combination
of primary colors.
3.
Students
can creatively express their understanding of the concept through an Alice
project they design.
Approach
·
Students will investigate
the splitting and mixing of light. Through this activity children learn that
not only can white light be broken up into the rainbow colours, but also that
the rainbow colours can be brought together to produce white light. Students
understand and experience persistence of vision.
·
Students will observe the
Alice presentation Newton’s Color Disc
SKILL DEVELOPMENT: Observing
an Engineering a small machine, Animation, Literary fluency.
BACKGROUND:
1. Show
the splitting of white light using seven colours.
2. Showing
the video made by using the Alice software showing the concept
3.
This would be followed by a
video quiz made by each group and play it in the class.
Life skills to be learnt:
a)
Like the colours of light
when we work in collaboration we should be one.
b)
Respecting intellectual work
of others.
Pre-requisite skills
·
Knowledge of working on Alice
·
Surfing the Net
·
Designing and working with
Newton’s color disc
Background Information:
1. Ordinary
light consists of the seven rainbow colours, viz. Red, orange, yellow,
green, and blue, indigo, violet.
2. Isaac
Newton was the first person to show that light could be split up into seven
different colors.
3. Just
as raindrops, prism, etc. can split white light into these seven colours so can
white light be made by mixing the seven colors together.
4. By
spinning the disc quickly the eye sees all the colours together (persistence of
vision) and so the disc appears white (in practice the disc appears off-white,
as most colours are not pure).
Student Activity:
Divide yourself into
groups of four
·
Design a presentation using
Alice ( For Formative Assessment)
o
Animation
o
Quiz
o
Game
o
Small Machine from trash to
demonstrate the concept.
