Activity:  Perception and judgement of color in Landsat images.

Pre-Activity:  Introduction to Landsat data.

Do Now:  How does color affect food choice decisions.

Aim:  To transform innate color judgement models into Landsat models for analysis, prediction, and mitigation.

Major Assignment:  Examine colors in Landsat images and assign quality judgements.

Processes, Skills, Goals:  Using remote sensing data to create and tell a science story.  Understanding benefits and limitations of the Landsat bands of color.  

Content:  Analysis of Landsat Images

Instructions:  Assess what students explained about judging food using color.  Explain that one's brain perception is driven by generations of evolution.  Landsat data is a new view of the earth's color using reflected EM radiation.  Explain three benefits and limitations of using Landsat data via slide show.

Materials:  Slide show on benefits and limitations of using Landsat data.  Landsat data examples.

Guiding Questions: What does color tell us about food?  What is food color a good choice for creating judgements about it properties?  Where does food color judgement come from?  Why are stoplights red?  Is green and go a soothing concept?  What happens when we perceive color elsewhere?  What happens when we examine color in a satellite image of the earth?  Is black good?  Green?  Brown?  How does our personal perception and interpretation affect our descriptions and therefore decisions?

Homework:  Visit the Landsat viewer, download a good image of the surrounding area, and explain what you see.  Choose a place where you would want to live, and explain why you think that would be a good place to live.
