Mad Scientists!

We put on our aprons and set out to experiment and discover.  Our first question - what simple things found around the house can turn a piece of coal into a garden of growing crystals? 

We read the steps of the experiment and then assembled our supplies and equipment. We needed:  chunks of coal, bluing, ammonia, salt, water, food coloring, a tablespoon measure, and a glass pie plate.
 
 
Cannon arranged the pieces of coal on the pie plate. Then we measured 2 tablespoons of the ingredients to a jar and mixed them until all of the salt was dissolved.  Cannon poured the mixture over the coal.  Then we started the stop watch so we would know exactly how long it took for the crystals to begin to grow.  It took 37 min. for the first tiny crystals to appear and 2hrs and 30 min.
for them to get large enough for a good look through the magnifying glass. 

 
While we were working we found more questions than answers.

What is the difference between growing crystals and growing plants?
What is the difference between a chemical and an element?
What is coal?
What is a crystal?
What does the word dissolve mean?
What is evaporation?
What does absorb mean?

And we just added the word research to our list of words to define and understand next week.

On Monday mom sent this picture of  "The Invasion of the Crystals"




Planting a Peat Pot Pizza Garden

 
Since we were in a growing mood Cannon selected some herb seeds to start for his “pizza” garden. We added warm water to the peat pellets. They absorbed the water and expanded until they were two inches tall.  Then Cannon carefully added a few seeds to each pellet. We put the “greenhouse” cover over the container.  It will sit in the warm sunshine and in about two weeks we should see some nice little leaves emerging from the little pots. When the plants get big enough we will plant them in a large bowl.  Cannon can harvest fresh basil and oregano for his pizza and a few mint leaves for his favorite summer drink.
 
Painting Time!   
This time Cannon painted with a brayer and printing inks. We added two different colors of blue and white to the ink tray.  Cannon got a good grip on the brayer and began loading the roller with color.  Then he rolled and dragged the brayer across the paper. He overlapped, changed directions, dragged the colors and tilted the brayer to “draw” lines on his paper.  He used all of his paper going right to the edges. 

 


For his second composition he chose red and yellow for Avalon.  Both compositions show a variety of textures and intensity of color.

We used the Fast Fact Flash Cards to practice adding four to numbers 1-12.  We enjoyed a Frog and Toad story and a chapter from Captain Underpants.  Then we used the Banana Grams and the Phonographics words to make some fun sentences.
