Recap:
Welcome back! I hope everyone had a restive and rewarding Fall Break and we're into the homestretch before Winter Break. I graded all of the work I had turned in before Thanksgiving and I have to admit, I was disappointed. I have been moving at a snail's pace making sure we cover everything in depth, but I can't do that going forward. This is high school and you are expected to copy down your own assignments and stay caught up with them. Case in point; less than 20% of my students turned in their STEM SIMS lab on time. Less than an additional 10% took advantage of my Power Hours and an extra week to get them done. Less than 50% of you completed the argumentation essay I asked you to write even though I gave you an additional two weeks to complete the steps.
Today we continued our discussion of the atom and the periodic table of ELEMENTS. I defined an element as a pure substance formed only of atoms and can be found in the Periodic table. I used examples of pure substances versus alloys and mixtures. Students also got a brief history lesson about gold miners and economic strategies of mine owners. They also learned where the thumbs up symbol came from.
Since there seemed to be much more comprehension, we branched out our discussion to include What defines a period on the table and what are groups or families. Check out this link: Periodic Table made simple. Imagine rows on the periodic table as sentences in a book. Every time you come to the end of a row, you have reached the end of a sentence. The end of the sentence is a period. There are seven (7) periods on the periodic table. Every element in a period has the same number of shells within the electron cloud. There can only be a MAXIMUM of 7 shells. I used the analogy of a town they might be planning and they place all the important buildings- police, fire, city hall in the center along with all the neutral buildings such as movie theaters, grocery stores, and malls, in the center. This represents the nucleus with the protons (+), neutrons (~). The different shells represent streets in their town all circular. The PERIOD tells them how many streets their town will have.
I then presented the formula 2n2. This tells them the MAXIMUM electron capacity at any given shell. For example, the first shell would be 2(1)2, meaning there can be a maximum number of 2 electrons on the first shell, or following our analogy, 2 houses on the first street. THAT DOES NOT MEAN THERE ARE 2 ELECTRONS THERE Automatically. Let's look at Hydrogen for example:.
Hydrogen only has one electron so it only has one "renter" to move into one house. There is still one open house in Hydrogen's Valence shell. Valence, meaning the outmost shell of any given atom. This is the most important shell since it is the one that determines what elements can bond with. We also said that all atoms like to be stable and therefore try to fill all their inner shells before moving to the next one.
We ended the discussion with groups but didn't get to cover it before the bell rang.

Students who correct ALL the mistakes on their returned papers will receive 10 points more. Make your corrections on a separate piece of paper and staple it to the actual paper, turn it in. Example: If you scored a 60 on an assignment and you correct ALL of the mistakes, I will add 10 points to make it a 70.
Entry Task/ Brain Bender:
In Hawaii, if you drop a steel ball weighing 5kg from a height of 45 inches, will it fall more rapidly through water at 20 degrees Fahrenheit or water at 40 degrees Fahrenheit or will it make no difference? Explain why.
