The following is a clip looking at carbon chemistry and life…

This next clip is Carl sagan looking at organic chemistry, carbon, and life on other planets…

The final clip is looking a Crash Course in Biological Molecules…

Keep in mind CONPTT as you watch this video clip and think about how this applies to the steps that we discussed in class. Also think about how important detailed observation is to ensure that the fundamental assertions of science are accurate.

Welcome to Mr. Kenna’s biology. I look forward to a great year. Here is a cool TV spot from BBC television advertising showing clips from their nature shows to the tune of What A Wonderful World, narrated by David Attenborough. Enjoy…
