Chemistry – s, p, d & f-Block Elements

Posted on by

CHEMISTRY: Wow! There’s a ton of interesting and important stuff to know about the elements! To make things a bit easier for you, I’ve consolidated the notes on each block into three separate vodcasts. Don’t forget to pay close attention to properties (physical & chemical), occurrence, and uses.

As you are studying, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. And don’t forget the topics I asked you to research for yourself: the nitrogen cycle, the role of transition metals in gemstones (know colors and elements), the role of transition metals in alloys (know names, elements and uses), where the phrase “mad as a hatter” comes from, and the symptoms of mercury poisoning and why you should be careful if you eat a lot of fish. Check out the Chapter 5 Stuff to Know sheet for more.

Physics 2-27-12 Bernoulli – Part 1

Posted on by

PHYSICS: So were you surprised about the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds! Here’s the lecture from Monday on Bernoulli – Part 1. Today we concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. Tomorrow we’ll take the practical applications to an even higher level (pun intended!). That’s the part I like best. 🙂
