POWER POINT NOTES: THE FLAVORS OF MATTER

Students:  HERE are the revised Power Point Notes for Unit 2, 'The Flavors of Matter'.

The Unit 2 Test is

Tuesday, October 4th!

You should be using these slides to complete your Unit 2 Study Guide of the same title.   

That Study Guide should be handed in before the beginning of Thursday's class in order to ensure that you have plenty of time to create your personalized, detailed copy of the notes in your Composition Book.

UPDATE: UNIT 2 SYLLABUS

STUDENTS: due to the disruption of classes caused by both alarms and attendance, Mr. Hatfield is revising the present Unit Syllabus.  

Four items have been removed, and about half of the remaining assignments have been reordered.  

Please notice, however, that you are STILL expected to hand in your completed Unit 2 Study Guide this week, and you are STILL expected to take your Unit 2 exam on Tuesday, October 4th.

VIDEO: 'THE LIVES OF THE STARS'

;

The following episode of Carl Sagan's Cosmos, 'The Lives of the Stars', forms the basis of a student homework assignment given in class on Friday, September 23rd.

 

  It can be viewed on-line currently HERE.

VIDEO: 'DRAWING ATOMS, HATFIELD STYLE'

In this VIDEO, Mr. Hatfield demonstrates his flat, two-dimensional, cartoony and unrealistic way to draw atoms. But that's not a bad thing.

Atoms don't 'look like' anything in the real world, so every attempt to draw them is going to be unrealistic in some sense: they're smaller than visibile light, after all!

But, Mr. Hatfield's way of drawing atoms does allow you to distinguish at a glance between the internal structure of a standard neutral atom, an ion or an isotope---and that can make all the difference in understanding the way that different substances (elements and compounds) actually behave.

VIDEO: THE PARTS OF AN ATOM

This video supports the basic knowledge needed to make drawings of atomic structure in Mr. Hatfield's Chemistry classes.  This knowledge will be tested and you will be expected to use those kinds of drawings on the Unit 2 Test.

UNIT 2 SYLLABUS

 

UNIT 2 BEGINS: THE EXPECTATION

 STUDENTS:  Today we begin Unit 2 of the course.

All work from Unit 1 is now past due, but may be submitted without penalty by Friday, September 16^th.

Students who have not yet completed portions of their Unit 1 Exam may come in to work on it today during lunch. 

Students who have yet to take the Unit 1 Exam will be given a Makeup Test that they will have to complete outside of class.

Students will be expected to hand in their Composition Books to be graded on Monday, September 12^th.

A detailed Unit 2 Syllabus will be provided next week.  In the meantime, our first assignment is Unit 2 will connect two topics covered in Unit 1, the nature of science and scientific notation.  That assignment will involve a video, ‘COSMIC VOYAGE’, which is available on-line, HERE:

VIDEO: "COSMIC VOYAGE"

Chemistry students will be viewing a 36-minute IMAX video in class beginning on Tuesday, September 3rd, and completing a worksheet based on part of the video. The film, 'Cosmic Voyage', was made in 1996 for the Smithsonian Institute and was clearly inspired by a classic science education film called 'Powers of Ten', originally produced in 1977 by the husband-and-wife team of Rae and Charles Eames.

'Cosmic Voyage' approaches the idea of using the metric system, which is based on powers of ten, to explore the question: "What is really large, and really small?" The film first zooms out from an acrobat's ring in St. Mark's Square in Venice, the place where Galileo first trained his telescope on the heavens.


Through 23 powers of ten, we leave first the Earth, then our solar system, then the Milky Way Galaxy behind, until we reach the limit of modern astronomy, where we can see images from about 13 billion years past.


Reversing course, the video then zooms in on drop of water in the Dutch town of Delft, where Antonie Van Leuuwenhoek first trained his early microscope to discover the hidden world of microbes.



As we zoom in on a paramecium, we penetrate its cell nucleus, then zoom in on a molecule of DNA.


Within that molecule is a carbon atom, and the world within that atom is mostly empty space! Within the atom, the atomic nucleus contains virtually all of an atom's mass, made of particles called protons and neutrons. These, in turn, are formed from even smaller particles called quarks.

The film continues with a discussion of the search for a fundamental theory in physics through the use of particle accelerators like Fermilab, along with an overview of the likely "recent" events that led to our sun, our solar system, the Earth and life itself.

Here, presented on YouTube, is the entire film,  if you wish to review the material or share it with others. As the narrator (Morgan Freeman) intones, 'we are all travelers on a voyage of discovery!'
