We studied the words ANALOG vs. DIGITAL.
Analog, continuous wave, degradeable
Digital, sampled wave, not degradeable in terms of sound quality.
AMPLITUDE: I actually drew this incorrectly for the class - I told them the amplitude is the height of a wave from peak to trough, but it's actually half that. Just from the middle up or down. Same concept, measuring size of the wave, but it bothers me if they remember my notation of the whole wave.

Bella and Issac will be joining us this year.

Sarah made an angel.

Meet Joseph's cousin. He will be part of our group from half way around the world.

Our Masters class completed their last presentations outside on the stage today! Brian joined in with the best presentation of all!


Orator Amanda captivated the crowd with her award-winning speech.


Isaac!


Kyle!

Melissa and Jessica!

Poor Kyle is being eaten!

Claire placed us into the first ever Reston Orchestra! She explained each of our instruments and roles and then allowed us to play our invisible instruments with classical music. Claire is definitely a TVTL (too valuable to leave). We love her dearly.


Lynne is a baby-monger. I can say this because I am constantly fighting her to hold babies. She has an incredible heart and wonderful hugs. Here Faith is being comforted while her mommy teaches us orchestra.


This was a scene from Isaac's family play. He was one of the Wright brothers finally flying their plane.


Linda takes our little ones so seriously. She has absolutely no fun with them at all. Today she brought in dress up clothes. Seven princesses and one prince!

Brian loves the history cards!


Nancy has cleaned our church every week for the last seven weeks! Wow! Nancy is incredible! Thank you! This week she needed to be elsewhere and our newest Harvest janitor took charge. Boaz made the men's room sparkle and smell great!

Revelations 21 reads Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away and there was no long any sea. I saw the Holy City of the new Jerusalem, coming down from heaven from God, prepared as a bride beautifully dressed for her husband....

The wall was made of Jasper and the city of pure gold, as pure as glass. The foundations f the city walls were decorated with every kind f precious stone. The first foundation was jasper, the sec0nd sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl...

If we believe in Jesus, that he is the Son of God, we will go to heaven. Heaven is a place with a city called new Jerusalem and the earth will be made new and new Jerusalem will be placed on the earth and we will live with God. It is a promise. When loved ones die who know Jesus we have the wonderful assurance that we will see them again, with God, and perhaps at the wall of new Jerusalem. What an amazing sight!

We made walls and streets of gold today to remind us how precious that day will be!


Nathan held his wall up high!


Justinian the Great made his out of pure carnelian.


Caleb's wall has a decorated pattern.


I'm pretty certain we won't see weaponry on the new Jerusalem wall but just in case Joel added a ballistic site.

Travis' wall is fantastic!


Isaac, always prepared and always brilliant, decided to build the pearl gates of the wall of new Jerusalem. He cut the foam board with his Leatherman and then placed jewels in the pearls to make a sparkling gate.


Melissa's street of gold is beautiful with real ridges.


Chris is always pinch hitting for us. Today I came late and Donna had to leave right away to tend to Grace. Chris jumped in and started cutting -- he even calculated and measured! Thanks Chris!


Now that I look at this picture I realize that Isaac could have cut his finger off. He was holding the foam board and cutting with his sharp Leatherman. Amazing what you miss when you're not focusing.

Dr. Lynnea, scientist supreme, had us dissect diapers today. Hopefully she'll email me the scientific explanation!

Melissa, Jack and Boaz were helped by Joel, Daniel, Caleb and Isaac today. They sang and acted out Oh My Darling Clementine while explaining the Gold Rush of 1849.

In a cavern, in a canyon,
Excavating for a mine
Dwelt a miner forty niner,
And his daughter Clementine

Oh my darling, oh my darling,
Oh my darling, Clementine!
Thou art lost and gone forever
Dreadful sorry, Clementine

Light she was and like a fairy,
And her shoes were number nine,
Herring boxes, without topses,
Sandals were for Clementine.

Oh my darling, oh my darling,
Oh my darling, Clementine!
Thou art lost and gone forever
Dreadful sorry, Clementine

Drove she ducklings to the water
Ev'ry morning just at nine,
Hit her foot against a splinter,
Fell into the foaming brine.

Oh my darling, oh my darling,
Oh my darling, Clementine!
Thou art lost and gone forever
Dreadful sorry, Clementine

Ruby lips above the water,
Blowing bubbles, soft and fine,
But, alas, I was no swimmer,
So I lost my Clementine.

Oh my darling, oh my darling,
Oh my darling, Clementine!
Thou art lost and gone forever
Dreadful sorry, Clementine

How I missed her! How I missed her,
How I missed my Clementine,
But I kissed her little sister,
I forgot my Clementine.

Oh my darling, oh my darling,
Oh my darling, Clementine!
Thou art lost and gone forever
Dreadful sorry, Clementine
