Day 62: False-Color Images

This slideshow requires JavaScript.

Astronomy: Today we did a false-color image activity.

Devise a color palette for the picture:

  • You may use only 4 different colors.
  • Assign each color a brightness key.

Look at each classmate’s picture and answer:

  1. What is different and what is the same as you look at everyone’s picture?
  2. Compare the pictures in terms of the pros and cons of using different color palettes.
  3. When you choose a different color palette, do the data change, or do we just see the data differently? Explain.

Here’s a copy of the student sheet: ASTRO Color Coding Activity
(Adapted from a Hands-On Universe activity.)

NGSS Science and Engineering Practices:
#2. Developing and using models
#4. Analyzing and interpreting data
