Students, you can download the Power Point Notes for Tuesday's Unit Test on Thermochemistry by either clicking HERE or on the graphic below:
Students should use this to complete their Study Guide, an Assignment which is due during Thursday's class, in order to prepare for Tuesday's UNIT TEST!
Students:
Here are the first 15 Power Point slides from Mr. Hatfield's Thermochemistry Notes. Use these to 'catch up' on completing the first two pages of the Study Guide on Thermochemistry. Click HERE or on the image to download these slides.
In this VIDEO, Mr. Hatfield models calculations that allow students to determine the frequency and the energy of a particular light wave seen in spectroscopy, as discussed in Section 4.2 of our text, and as seen in the Bright Line Spectra Lab.
BUT JUST AS IMPORTANT, Mr. Hatfield AGAIN models the use of a notation for displaying very large or small numbers that mimics with the 'EE' key found on many scientific calculators.
This method was previously taught in class. It is a SUPERIOR method that saves time, reduces the likelihood of student error and has students writing out these numbers in a form that matches the way they enter those numbers into a calculator!
And, since students will continue to use that method for the rest of the course, it is important that students master the use of that method for future success.
Students: HERE is the latest set of Power Point Notes.

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