Humidity – The moisture content of air

Absolute Humidity – The mass of water vapor contained in a ceratin volume of air

Relative Humidity – The ratio of the mass of water vapor in the air at a given temperature to the maximum mass of water vapor the air could hold at that temperature, expressed as a percentage

Greenhouse Effect – The process by which certain gases (principally water vapor, carbon dioxide, and methane) trap heat that radiates from earth

Lyrics:

What does the glass of a greenhouse do?
It lets the short solar rays pass through.
The objects in the house absorb these rays
And re-radiate them as long heat rays.
What does the glass of a greenhouse do?
It doesn’t let the long heat rays pass through.
Trapped by the glass they bounce back and forth,
Re-radiated and re-absorbed.
Stay! Stay, you long heat rays!
Warm up the house on cold, cold days!
Stay! Stay, you long heat rays!
Warm up the house on cold, cold days!
The atmosphere is like a greenhouse, too.
It lets most of the solar rays through.
The surface of the Earth absorbs these rays
And re-radiates them as long heat rays.
There’s vapor in the air, what does it do?
It doesn’t let the long heat rays pass through.
Trapped by the vapor, they bounce back and forth
Re-radiated and re-absorbed.
Stay! Stay, you long heat rays!
Warm up the house on cold, cold days!
Stay! Stay, you long heat rays!
Warm up the Earth on cold, cold days!

Global warming = the concentration of carbon dioxide (and other greenhouse gases) being so great that the greenhouse effect would warm the earth up too much, causes problems with the ecological balance. 

Global Warming???

What is Ozone? A molecule composed of three oxygen atoms. It is an AMAZING filter!

Ozone: Good up high, bad nearby.

The Lonely Homeschooler

Have you ever wondered if you are causing your children to be forever lonely by homeschooling them? While some siblings get along just great, others seem to be the lone sheep in the family, constantly searching for a companion. A ‘bosom friend’ as Anne Shirley would say.

This article by Melody Lyons was shared to me by a good friend.

A siblings ‘girls night’. Painting nails, face masks, hair styles, food and a movie.

In it she addresses every mother’s concern for her children. She affirms what I have been thinking for the past few years, ever since we pulled all of our children from our private Catholic Schools.

Melody begins with:

This article is written primarily for homeschooling parents who wonder if their kids will ever find true, Christ-centered friendships with someone of similar age… and also for those parents who avoid homeschooling because they are afraid for the same reasons. I will spoil the ending for you in this first paragraph but then you still have to read the rest of the post. The answer to your question is: Likely, but not certainly.” >>more…

This is well worth the read and I would love to know your thoughts. Either comment here or head over to my Facebook page.

~ Have a simply happy homeschool day!
