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…
The focus of the following clip is the physical properties of water…remember water is a POLAR molecule.
The following clip looks at the two types of chemical reactions…
Remember also the kinetics of a reactions (the relative energy of reactants, products and the role of activation energy).
Endergonic vs. Exergonic Reactions
Here are some videos that review what we covered in class.
Types of Matter: Elements, Compounds, and Mixtures (Professor Dave Explains)
Chemical Bonds: Covalent vs. Ionic (Bozeman Science)
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…

Today we talked about what an ecosystem is. This video reviews some of our key terms and reviews what an ecosystem is.
Remember our ecological hierarchy (or levels of organization)
Here is a video clip that reviews how evergy flows through an ecosystem and covers nutrient cycling.
Remember the following relationships:
Keep in mind that energy flows ONE WAY through an ecosystem, while nutrients are RECYCLED.
Here are some videos looking at the relationship between photosynthesis and cellular respiration
