Quantum Numbers Explained...

Still not sure about those Quantum Numbers? Hopefully Mr. Anderson can help in the above video. Remember there are four numbers along with electron configuration that will be taught in this section and introduced in the video below . Please leave a comment when you have watched both videos. Thanks!

Speed, Velocity, and Accerleration...

It's important that you understand the difference with speed, velocity, and acceleration. Mr. Anderson does an excellent job describing this difference. Please leave a comment below once you have watched the video so I know you have completed your assignment. Thanks!

Spanish Quiz Reschedule...

The Spaish vocabulary quiz scheduled for Wednesday, October 5th, will be given on Thursday, October 6th  Be prepared to do both the Verse Test and the Vocabulary Quiz.

Kinematics....

In Section 4A we learned that mechanics (the study of motion) can be broken down into three categories: Kinematics  (the description of how things move), Dynamics (the description of what causes things to move), and statics (the description of how stationary things react to pushes and pulls--stationary being the key word here).

Section 4B introduces us to Kinematics or the description of how things move by measuring positions, speed or velocity, and acceleration of the objects being observed. Let's deal with the objects position to start with. This leads us to the difference between distance and displacement. Distance is a scalar quantity where you take the individual lengths in your trip and add them up to get a total. On the other hand, displacement is a vector quantity is measured as the shortest distance between where you started from to where you ended at. Looking at this mathematically, distance uses addition of the total lengths involved in the motion while displacement deals with the difference from the start to the finish. Calculating these two is described in the video below.

Scalars and Vectors...

In Chapter 4 we are learning the very basics of mechanics, or how objects move. When we first look at a moving object we must take into account the system (a boundary that clearly defines the limits of the objects or processes being studied) before answering the questions "How" the object is moving. Once the system is defined we need to determine the point of reference, or the space where we are making our observations from.  There are several different types of points of reference: inertial (movement in a straight line or simple curved path), accelerated (when observational point that is not moving at a constant speed or direction), or a rotational (forces felt while on a spinning reference frame, i.e. The earth).

Motion occurs over a period of time measured in seconds (s) and the length of that time span is known as an interval (represented by delta [triangle] t). We must correctly identify the time interval  as an important part in understanding how things move.

In a system a scalar or a vector are used to describe the motion of an object. The above video by Mr. Anderson at Bozeman science will give you a good understanding of the difference between these two and how they relate to motion.

The Electoral College Explained...

Not understanding what the Electoral College is and how it functions? This video published by TedEd will explain exactly how our voting system works!

History of the Atom...

Chapter 4 in Chemistry takes us back to the very foundation of our periodic table. Since we will be dealing with elements, and more elements, compounds of these elements in different shapes and forms, including equations, we need to understand how each element is identified. We call this the "fingerprint" of each individual element and that is the atoms that make them up. So here is the history of how the atom was discovered done by Mr. Anderson from Bozeman Science. Be sure to pay close attention to the names and the particular experiments used to discover the tiniest particles of matter.
