Sometimes we all need to know more about things than answers that result in grades only.   A friend of mine told me a story about being on the water and approaching port with his wife.   "Which side of the red light should we be on" he asked.   The response was "I don't know".    But he responded "didn't we both take the seamanship course and didn't you get an A".    "Sure" she answered "but that was only to get a good mark.  I forgot all that stuff when the course was over".

Some things require more than a good grade.   They require an in depth understanding of the basic underlying principles.    This is what this page is about.  Hopefully it will be updated in time .  Of course these must be done with adult supervision.  We are not liable for any loss from these experiments or material.

In dwelling be close to the land.
In mediation delve deep into the heart.
In dealing with others be gentle and kind.
In speech be true.
In work be competent.
In action be careful of your timing.
