US Grade 3 - 6

Everything we use today seems to be wireless, which of course means it has a radio inside it.  This class explains how a radio actually works, what radio waves are, and what the main components of a radio are. This basic understanding applies to anything wireless (except infrared) including wifi, garage openers, bluetooth, etc.

Concepts explored in this session include: 
The nature of radio waves
Antennas
Frequencies
Modulation
AM/FM
Radio frequency and power for range
What can radio do?

All of this is presented in an age appropriate manner so the younger students can grasp and start on a proper understanding into the world of computers. 

This is an interactive whiteboarding class where illustrations are used explain the lesson throughout.  Interaction means questions and comments are encouraged  to whatever level of participation the student desires. 

 
      ==========

This class is part of a series on physics and how things work around our homes. Each class is independent, and can be purchased separately. I recommend taking all the classes to become well rounded!

Teacher expertise and credentials

Learning facts and skills is definitely important, but an often missed but critical piece of education is understanding the foundation. Without a proper understanding of the underlying principles of "how something works," the collection of facts are not only less useful, but often dangerous. It is the understanding of principles that makes interpretation and application of facts possible. By achieving a basic understanding of the principles, it is possible to truly master life skills.

I am mid 50's, Father of 12 children and 4 grandchildren. My life experience is one of constant learning, across many disciplines, resulting in a very broad understanding of everything from the basic skills of life to deep high technology and innovative agriculture. I have several patents in my name and I am releasing a series of books on food and health through profitable small farms. 

As a homeschool Dad, my desire is to bring a wealth of basic understanding to the next generation. Not how to use things, but how they really work. The type of understanding the next generation misses through education designed to only teach how to use something. 

My classes are intended to give enough understanding to peak interests for further learning through independent research. Each class covers a single topic, at a deep enough level to empower the student to dive further successfully.  There is no pre-requisite except a love of understanding. If you are looking to just know how to use something, this is not the place. But if you want to learn how life works, if you love to understand how this or that works, then come along on this journey of exploration into the beautiful simplistic complexity of life and nature. 

The classes I teach are independent in addition I offer classes organized into series. It is not a requirement to take all the classes in a series, nor is it required to take them in order. This is designed to give you the most flexibility in scheduling. Also, the classes do repeat often and on different days and time slots, so that if you can't make one class there will be another soon that will match your schedule. 


See you in class!
