Grade Level: 7th and up; Type: Physical Science and Mechanics

Objective:

Discover whether DSLR (Digital Single-Lens Reflex) and Point-and-Shoot cameras work the same way under all conditions.

Research Questions:

What is the difference between DSLR and Point-and-Shoot cameras?

Cameras date a long time back. The pioneer camera is called the “camera obscura” which was basically a box with a pinhole in it that allowed people to see external images on another surface. Cameras evolved ten-fold over time from big boxes to the tiny compact ones we use today. Cameras once only captured black and white, but now it is captured in color and digitally, without film. In this experiment, we will test the latest in camera technology to see how they compare in bright conditions, normal conditions, dark conditions, motion, and closeups. In the process, students will gain knowledge of how each  camera works to produce such images.

Materials:

  • Three DSLR Cameras
  • Three Point-and-Shoot Cameras
  • Pen and paper to take notes

Experimental Procedure:

  1. Take your first camera and take a photo under very bright conditions and evaluate the results of the photo.
  2. Do the same thing for your other cameras and also under dark conditions, normal conditions, motion, and closeups.
  3. Use the chart below to organize your findings:
