The Language of Science and Math

Use facial expressions and sounds to express your reaction to the following equation:

 (pr²)(1-A)(SI)=(e)(4)(pr²)(s)(T⁴) 

This is the basic relationship we used to find the relationship between emissivity and temperature.  This is then related to  CO₂ concentrations and its relationship to global warming.

 How would you rate this equation for level of difficulty based on a scale with 1= easy and 5 = difficult?

Often, the language of science and math is intimidating. 

Let's challenge ourselves.  We might find out that we're smarter than we think we are.

Your goal is to understand the formula given above and its relationship to computer climate models and global warming.

1.  A good problem solving approach is to list the information you already know about the topic.  

 a.  Do you recognize any math terms that seem familiar to you?

b.  What does T generally indicate in science and math formulas?

2.  Read "Basic Earth Systems". 

3.  Complete the Worksheet.

4.  Try the "Emissivity" Activity.
