VIDEO: THE BUNSEN BURNER

VERY IMPORTANT:  On Monday, Oct. 4th, all of Mr. Hatfield's classes will be doing an activity that involves gas.  Students are expected to know how to do this safely!

Mr. Hatfield has made a video to demonstrate the correct way to use the Bunsen burner.  Make sure you review this before you come to class on Monday, as we will be using the Bunsen burners in class to perform the 'Flame Test Lab'.

VIDEO: RED TAPE ON THE FLOOR

Some students have suggested that I should do more about my aging, overcrowded classroom.   They think I should raise a complaint, and get people to understand how rooms like mine make it difficult for students to achieve.

Well.  I can't say that my students are wrong on that point.  Our situation's not that great, I admit.

But this situation is also something that's definitely in my wheelhouse, as this video from the summer of 2020 should show:

VIDEO: DRAWING ATOMS, "HATFIELD STYLE"

In THIS video, Mr. Hatfield demonstrates his cartoony, unrealistic way of drawing atoms, where '+' are protons, '0' are neutrons and 'e-' are electrons.


Every attempt to draw an atom is, in some sense, unrealistic: after all, atoms are smaller than the waves of visible light which our eyes use to form images. In a sense, atoms don't look like ANYTHING.

Yet, while unrealistic, mastering the use of these symbols can help students develop a better understanding of atomic structure, which can be applied to ions and isotopes as well as neutral atoms.

POWER POINT: THE FLAVORS OF MATTER

Students:  HERE are the Power Point Notes on 'The Flavors of Matter', as shared in class between Aug. 31 and September 9th.

Please note that the final slides not only demonstrate how to write nuclear notation to show isotopes, but that it contains an image of that notation with 'atomic drawings, Hatfield-style', as shown in class and shared on Teams.
