Workshopmatics Forum-matics Singa-matics Concept-matics Model-matics ] Subscribe To This Site The Constant Difference Concept The Constant Difference Concept is derived from the Comparison Concept . This concept is applicable when the problems deal with an equal quantity being transferred in or transferred out of the two variables concerned. This leaves the two variables with an equal increase or decrease in value. The unique feature in this concept lies in the fact that after the transfer in or transfer out of quantities, the difference between the two variables remains unchanged, hence the name "Constant Difference" Concept. To illustrate this concept, take a look at the following problems. (A) Equal Amount Transferred into 2 Variables Question: Ken had 14 pens and Ben had 2 pens. When they received an equal number of pens from their teacher, the ratio of Ken's pens to Ben's pens became 3:1. How many pens did each of them receive from their teacher? Answer: For this question, we will work backwards. It is always easier to start drawing models where a multiples-relationship exist, i.e., a variable is a multiple of another variable. In this example, Ken is 3 times of Ben after the transfer in. Step 1: Since the ratio of Ken's pens to Ben's pens after the transfer in is 3:1, we draw 3 boxes to represent the number of units that Ken had and 1 box to represent the number of units that Ben had.

Home Science Notes Web Links Biomes ... Lessons Following the Energy Trail Let's see how the sun's energy flows in the Biosphere. Warning: I am making a lot of assumptions and doing a lot of rounding in the math here. My numbers may be off by several thousand percent, but I think the process is all right. Try to understand the basic idea, and don't use my math numbers on any Important Exams unless you have checked them out! Dr Viau says, "Gerald Nordley and Mark Wistey were kind enough to help with this, but I made the mistakes all by myself!" The Solar Constant How much of the sun's energy gets to the surface of the earth, and what does that mean to a lemming? The earth gets only 2 billionths of the sun's energy, but that is still a lot. However, you can see on the chart that life (through photosynthesis) uses only 023% of the energy that reaches the surface of the earth 34% of the sun's energy is reflected back into space by snow and clouds. This reflective quality of a planet is called its
