UNIT CONVERSION, STEP BY STEP

The attached graphic models (again!) the steps involved in unit conversion, as taught in class. If you haven't mastered the method, download the graphic:

VIDEO: EXPERIMENTAL DESIGN AND SIGNIFICANT FIGURES

Students:  here is a new VIDEO that introduces a concept that you must ALWAYS employ when performing calculations in Chemistry. 

Well-designed experiments take place in controlled conditions that account for variables, and which express their results in significant figures in order to handle the inevitable limitations to measurement that will occur.

When we do math in this course, we are NOT engaged in an abstract exercise in which the answer is simply a number for someone unknown variable, 'x'.  Instead, we are attempting to measure real phenomena and make predictions about what these phenomena will produce in the real world.

In that real world, there are limits to the ACCURACY and the PRECISION of our measurements.  Students must understand the difference between the related but distinct concepts!   Students must understand that the limits require us to not express our results with an UNREALISTIC level of precision, that was NOT actually observed!

POWER POINT: THE NATURE OF CHEMISTRY

Students:   HERE is a link to where you can get the Power Point, 'The Nature of Chemistry', which is used to help complete the Study Guide of the same name:

Remember: that Study Guide is a relatively-easy Assignment given to streamline the process of note-taking in this course.   You want to complete every part of it and hand it in as soon as possible, as it will be graded and returned to you in order that you can create your complete, detailed Notes inside your Composition Book:

You are not allowed to use the Study Guide on the Unit Test, but you ARE allowed to use your Composition Book, so this is really a very important routine that you must maintain in this class.  Make sure you do!

WELCOME BACK! THIS IS CHEMISTRY!

 Students, my name is Scott Hatfield, and I will be serving as your Chemistry Instructor in the 2021-2022 school year.

                                   

We live in interesting times, in a world of unexpected challenges.  

In our case, the most obvious challenge is working together at school to create a safe environment that supports all students. 

To help support you, I've created a virtual classroom page that has built-in links to supporting materials and important information that you would want at your fingertips:

I've also begun setting up our individual classes, and when you go looking for them on Teams, I hope they'll be easy for you to find, and even FUN for you to use!

We'll use MICROSOFT TEAMS to access our individual classes, obtain materials and send out many important messages, many as links to THIS blog!    

We will also have a new textbook created for California students, Experience Chemistry.   

While you will receive an actual student text to work with, we will often access the digital version of this curriculum, on-line.  To do this, you will need to access this through the Clever app.  Log on HERE, using your FUSD student account:

Once you are in, you will find the 'Saavas Realize' link, that will take you to where you can log onto the digital curriculum, as shown below:

Just like Microsoft Teams, the online version of the text will be organized around classes---and your student information should already be imported into those classes.  Pretty convenient!

NOW, ALL OF THESE RESOURCES are important.  You will need to be able to access and use all of them.  

But, in addition to all of that, the main way you'll receive information about events in my class is through the virtual classroom page and this blog, 'Chemistry Knights'.   

I encourage you to explore both!  WELCOME TO CHEMISTRY!
