The Three Phases of Matter -- posted by John, George, and Richard

We did some science experiments to show the different phases of matter (solid, liquid, gas), by using different materials to create each phase.

First, we put seltzer water in a jar and dropped raisins in it. The raisins were heavy and went to the bottom of the jar, but the gas bubbles from the seltzer water attached to the bottom of the raisins and lifted them to the top of the water. Once the gas bubbles popped and dispersed into the air, the raisins sank to the bottom again. Then they collected gas bubbles and did it all over again. They continued to go up and down and up and down even while we were doing the other experiments.

The next experiment we did was to add vinegar to a bottle with baking soda in it. When the liquid vinegar and the solid baking soda are combined, they make carbon dioxide. When we quickly put the balloon on the bottle, it captured the air that had been displaced by the carbon dioxide. Carbon dioxide is heavier than air.

In the next experiment we put a fizz tablet in a jar of water. The fizz tablet contains citric acid and baking soda. The water causes the citric acid and the baking soda to combine and it makes a gas. We watched the gas bubbles float to the top of the water and escape into the air.

After mixing liquids and solids to make gas, we then mixed solid and liquids to make something really fun. So much fun that we were joined by the older boys: Will, Spencer, and James. And they loved it!

This was the most exciting experiment by far, even though it was simple. All you do is add 1 tablespoon of water to 2 tablespoons of cornstarch. It makes a substance that behaves like both a liquid and a solid!

We poured it in our hands as a liquid, and then when we squeezed it, it became a solid. If we just held the solid in our hands, it turned back into a liquid! We all played with it for a long time.

In the last experiment we combined two liquids and a solid to make slime. We combined Borax, water, and glue, plus three drops of food coloring. At first, it was liquid-y and could be played with like slime. Then, when it was poured into James's hand, and he kneaded it and squeezed it for about 5 minutes, it became a solid and he rolled it into a ball! It was a very bouncy ball! Mom said when it quits raining, she'll let us make more slime and balls, but that should be an outside project.





This is the bouncy ball with its little buddy:

Earth is Our Favorite Planet -- posted by John, George, and Richard

To answer your question, Mr. Billy, even though Earth is obbo (Billyism) our favorite planet, because it is God's masterpiece and where he sent his only begotten son to be born and die and come back to life, we also like Pluto because it is so little and lost its status. Saturn is special for its rings. George and John like Jupiter because it is the largest. John made that one on the model. He also made Saturn. Richard made Pluto, the Sun, and Neptune. George made Uranus, Mercury, Venus, and Mars. James made Earth for us because he's good at painting. Earth is the center of the Universe.

Our Solar System -- posted by Richard, John, and George

This is the model we made of our solar system. It's obviously not to scale, and you'll see why when you watch the Bill Nye video.

Where's M. Night Shyamalan When You Need Him -- posted by Sarah Grace

Recently, Mr Billy and I had been talking about our first Bibles, and today I went in my room to pull mine out. It's a light pink children's Bible, and I received it for my birthday when I turned eight. Today as I flipped through it, I noticed some hot pink highlighter marks. There was only one chapter highlighted, and it was Psalm 103. I have no memory of doing that, and I didn't take much notice of it at the time because I was too tickled with taking a picture to show Billy the pink highlighting eight-year-old Sally drew in her pink Bible, as I knew he'd get a kick out of it.

Later, Mom read Psalm 103, since she had seen I had highlighted it. She came to me in the kitchen with tears in her eyes--

It was the very Psalm I chose to read during my eulogy for Webb.
