Biodiesel video

Unfortunately I do not have the link to Dylan's video since I'm in New York, but I saw it and it looks great! I'm glad he was able to finish it on his own, I feel awful about it.

What is Biodiesel?

I've learned a lot about biodiesel in these few days researching it for Dylan and I's video. I think Biodiesel.org explained it best:

"Biodiesel is a renewable, clean-burning diesel replacement that is reducing U.S. dependence on foreign petroleum, creating jobs and improving the environment. Made from a diverse mix of feedstocks including recycled cooking oil, soybean oil, and animal fats, it is the first and only EPA-designated Advanced Biofuel in commercial-scale production across the country and the first to reach 1 billion gallons of annual production. Meeting strict technical fuel quality and engine performance specifications, it can be used in existing diesel engines without modification and is covered by all major engine manufacturers’ warranties, most often in blends of up to 5 percent or 20 percent biodiesel. It is produced at plants in nearly every state in the country."

Now we start making a video

More Lectures

Chemical bonding revolves around one concept: a covalent bond is formed by sharing electrons. We do not focus on ionic bonding too much in this unit. Atoms want electrons to fill their valence shells to make them stable. More often than not, it's 8 electrons to fill a valence shell except for Be, B, H, & He. We learned lewis structures, formal charge, electron geometry.

Atomic Model lab

Basically this lab was about practicing have need share. I've been having a lot of struggle focusing so this stuff is still lost on me. I'm trying though

Good luck on the test/quizzes everyone!

Unit Test Thoughts

Well, I don't have the grade back yet... but I think I did pretty okay. I actually got to read all 50 questions, which is rare for any unit test. So I'll count that as a victory.

Periodic Trends

The last lesson for this unit was periodic trends. The periodic table has trends that can provide information about the chemical and electronegative characteristics of S & P block atoms. i believe this concept was very easy to understand as long as you memorize the details.
