Climate Changes Creating Green And Flowering Mountains
http://www.sciencedaily.com/releases/2008/05/080516121650.htm
Scientists at the University of Sweden are reporting the effects of a 1 degree increase in temperature on mountain ecosystems. They says that because of the increased temperatures, many tree species are now growing in higher altitudes than they used to be found, and that this is true for many plant species, as well. Because of this, new species of animals are moving into the area, too.
This is interesting, because we have talked about the effects of global warming in many of my classes in school - all the way back to elementary school! But usually we just talk about all the bad things that will happen. This article doesn't just focus on the bad stuff; the scientists mention that the harsh areas of the Swedish mountains will become more liveable - not necessarily a bad thing! But, they also say that there will be bigger changes if temperatures rise the predicted 3 degrees by 2100...which could be bad.
To complete today's assignment (must use Internet Explorer!):
1. Go to the page on drag-and-drop pedigrees (it's at www.zerobio.com which is awesome!)
2. Solve each problem by building the pedigree and answering the questions.
3. Raise your hand and show me your work for credit.
4. Submit each problem to check your work.
5. After completing all four pedigrees, complete the quiz and show me your results.
This is a good animation that shows independent assortment. This topic tends to be really confusing, no matter how many times I move the chromosomes around on the board. Let me know if this helps!
This link takes you to a video that instructs you how to make a Punnett square. Pretty good stuff if you're still confused after class (or if you missed it!)
Try this click-and-drag activity using principles of Mendelian genetics. It has great practice with genetics vocabulary and Punnett squares. There are three practice crosses followed by a pedigree. We'll do those later! *Must use InternetExplorer*
