Filtering and Mixing Light
Learning Objectives
- Understand how colored light can be produced using filters and how filters work by allowing only certain colors of light to pass through.
- Recognize the primary colors of light (red, green, and blue) and how they can be mixed to create other colors in the visible spectrum.
- Explore real-world applications of light filtering and mixing, such as in stained glass, stage lighting, and traffic lights.
- Explain how digital displays like televisions and monitors utilize primary colors to produce a wide range of colors.
- Investigate how computer graphics software uses primary colors to generate precise shades for digital art and design.
Introduction and Hook
Show an image of a stained glass window to illustrate how filters work by allowing only certain colors of light to pass through.
Direct Instruction
Explain how colored light can be produced using filters and the primary colors of light (red, green, and blue).
Discuss real-world applications such as stage lighting and digital displays that use light filtering and mixing.
Guided Exploration
Watch a video on how digital displays use primary colors to produce a wide range of colors. This video helps students understand the practical application of light mixing.
Engage in a discussion about how computer graphics software uses primary colors to generate precise shades for digital art.
Hands-On Activity
Conduct an experiment where students use colored filters to observe how different colors of light are produced.
Have students create their own stained glass designs using colored cellophane and observe the light passing through.
Independent Practice
Assign students to explore their environment and identify examples of light filtering and mixing in everyday objects.
Encourage students to use computer graphics software to mix primary colors and create digital art.
Check for Understanding
Use the 'Forms of Energy' assessment to reinforce vocabulary and concepts related to energy and light.
Discuss students' findings from their independent practice and clarify any misconceptions.
Review and Reflection
Review the key concepts of light filtering and mixing, and how they apply to real-world scenarios.
Encourage students to reflect on what they learned and how they can apply this knowledge in their daily lives.
Assessment and Extension
Assign the 'Visible Light – Comprehension' assessment to evaluate students' understanding of light dispersion and color perception.
Encourage students to explore further by researching how light is used in technology and art.
