This week, we got in to two different caucus groups and did various activities. We first separated our class into two groups. One group was for girls and the other group was for guys. We then got separated and discussed over our experiences. And two
Global climate change and conflict 5/4 It is increasingly likely that the next century will be characterized by shifts in global weather patterns and climate regimes. Change in risk of malaria by 2080 -mosquitoes will be able to live in places that t
5/6/09 Restoring Ecology Ecological restoration and global climate change -Mismatches-ex. -great tit( relative of the chickadee) -caterpillar-food source -today, mismatch, food source is not available to feed tits -caterpillar hatches little earlier

FINAL Strong Inference: disprove hypothesis and accept hypothesis that cannot be disproved. 1) Devise multiple hypothesis 2) Design experiments to eliminate one or more of the hypotheses 3) Carry out experiments in a manner that gives a clean result

Global climate change 5/1 Solar energy: incoming and outgoing -heat is stored and redistributed by winds and currents on Earth's surface. Earth's energy budget -temp of the surface of plant, how much energy comes in and how much energy gets radiated.
