About pinhole camera

1. GRADE VI Science Date : 26.11.2023 Product Realization: Application Orientation Session Number: 4/8 Learning Intent: Light, Shadows and Reflection Associated learning Intent: Pinhole Camera Extended Associated learning Intent: 1. Prove light travels in the straight line. 2. Characteristic of pinhole camera.

2. Learning Outcomes: 1. Explain the construction of pinhole camera. 2. Deduce the principle of pinhole camera. Thinking Routine: I See, I Think, I Wonder. Skill: Handling apparatus Teaching Materials: Essentials to make a pinhole camera. Pedagogy: Experimental

3. LEARNING PROCESS Engage: Prerequisite knowledge: Recall the previous session about Light – A form of energy. Introduce the real model of camera Start by introducing the concept of how cameras work and the basics of light and optics. Show them some simple images or videos illustrating pinhole cameras and their principles . GD: Encourage students to share their thoughts about the history of cameras.

4. Explore Allow students to experiment with making small pinhole cameras using materials like cardboard, tape, aluminum foil, and a small piece of photographic paper or light-sensitive material. Let them explore creating different shapes and sizes of pinholes to understand how they affect the image. (Peer group Activity) Thinking routine: Why do you say so?

5. Explain Guide the students through the scientific explanation behind pinhole cameras, discussing concepts like light rays, the formation of images, and the role of the pinhole in capturing light. Principle: 1. How tiny holes acts as a lens. 2. Creating a inverted image on the photo-sensitive paper . 3. Characteristics of image in pinhole camera

6. Elaborate Encourage students to build larger or more complex pinhole cameras, experimenting with different materials, or creating a pinhole camera obscura to project images on a larger surface.

7. Evaluate Assess their understanding by asking questions, having them present their findings, or creating a small exhibition of their pinhole camera creations. Home work: Prepare album of collection of camera . HOTS: 1. If a pinhole camera’s image appears blurry what adjustments could you make to improve the clarity? How would altering the pinhole size affect the image? 2. Design the scenario where a pinhole camera would be more advantageous than a regular camera. justify your choice based on specific features of the pinhole camera.

8. Learning Reach If it is less than 45 % - Revisit the plan If it is 70-90 % - Remedial will taken and given a activities. If it is reached more than 90% go for the hots of the session.

9. Cross curricular connect Mathematics – Calculate the focal length of the pinhole camera, measure angles, and estimate the size of the pinhole required for different focal lengths. This involves geometry, trigonometry, and basic algebra. History – Investigate the history of photography and the evolution of cameras, starting from pinhole cameras to modern digital ones. Study famous photographers who used pinhole cameras and their contributions to the field. Art : Use the pinhole camera as a tool for artistic expression. Explore composition, framing, and the creative aspects of photography. Analyze pinhole images for their artistic qualities, such as light, shadow, and perspective.

10. Cross curricular connect Technology: Discuss the technology involved in cameras, including the transition from pinhole cameras to advanced digital ones. Explore the components of a modern camera and how they function compared to a simple pinhole camera. Social Studies: Explore cultural aspects of photography, examining how different cultures have used photography throughout history and how it has influenced society. Environmental Studies: Discuss the environmental impact of different types of cameras. Compare the materials used in making pinhole cameras to those used in modern digital cameras in terms of sustainability and environmental friendliness
