SPECTRUM OF LIGHT

2. OBJECTIVES Updating and generalization of the concept of light.
EPP BG-EPPKA3-PI-FORWARD
Updating and generalization of the concept of light.
Clarifying what white light is
To acquaint students what spectrum is
What is causing the color of objects

3. 562113-EPP-1-2015-1-BG-EPPKA3-PI-FORWARD
EXPECTED RESULTS
1. To know that white light is complex and consists of many colors (experience with Newton's prism rainbow) bundle of these colors is called a spectrum of white light
2. Connect the colors of objects with the properties of light.
3. Understand that bodies have color because they reflect in different ways and absorb light beams of different colors.
4. Understand what determines the color of objects

4. Lesson Plan Lesson Plan: 1. Newton’s attempts
EPP BG-EPPKA3-PI-FORWARD
Lesson Plan:
1. Newton’s attempts
2. Spectrum of light. Rainbow.
2.1. Spectral colors
3. Color of objects
3.1. Depends on their ability to affect differently the different colors
3.2. Depends on the spectrum of the incident light
3.3. Depends on the perception of the human eye

5. ACTIVITIES OF STUDENTS

STROKE OF THE LESSON
ACTIVITIES OF TEACHER
ACTIVITIES OF STUDENTS
Update knowledge of light from previous lessons through in-:
What is light?
How does the light spread?
What is reflection and refraction of light?
Have you seen the beautiful rainbow that appears after rain. How do I get these beautiful colors?
It tells how over the years, scientists have given different hypotheses about the color of their bodies and experimental establishment of Newton that white contains all the others.
1. Answer the questions:
examples – something that shines; fire of the sun; straightforward; mirror; on the border of two areas / If they have trouble answering assist with sample images /.

COLOUR OF BODIES
COLORS

10. What have we learned? White light is complex and made up of colors.
EPP BG-EPPKA3-PI-FORWARD
White light is complex and made up of colors.
The beam of these colors is called the spectrum of white light.
The color of object is due to their ability to reflect the colors differently
