Theme

What is the theme or topic to be presented?

Students will design an optic device that displays a virtual image by 

implementing their knowledge of the principles of reflection, refraction and 

deviation of mirrors and lenses. 

Learning Objectives

Students will be able to:

• Determine the appropriate materials necessary to build a camera obscura

• Explain the difference between translucent, transparent and opaque

• Understand how light interacts with matter to create an image

• Calculate the angle of deviation of the lens using Snell’s law

• Incorporate mirrors and the data derived from Snell’s law into the camera 

obscura in order to invert the image

• (Optional Extension) Modify the camera obscura to be a phone projector 

that shows the images right side up.
