Live Oak Fishing

 Check this out! It's the Live Oak fishing dock!
Everybody caught a fish down here.We had to wear life vests so if we fell in the water we would float. The biggest fish caught at live Oak was 5 pounds. Mostly all of the fish were catfish. But there were some blue mouth bass and a couple other fish. We got use live bait. They were worms. Some of the girls got freaked out. There were at least 2 dozen fishing poles so every one got to have one. The boat ramp we had to walk on to get down to the dock was very steep. But mostly I think every one had fun at fishing.

Mixture Lab

the mixture
In science we made a cool but gross mixture with flour, salt, water, and mulch. We were separating the materials. We used a screen and poured the mix into another cup to remove the mulch. After we poured it, the mulch stayed on the screen. The next day the flour settled on the bottom, and we decided to try and separate the salt from the water. We did this by taking 5mL and put it into a petri dish. After two days the water evaporated and the salt was the only thing left on the petri dish.

MATTER AND BILL NYE

Lately, the science class of room 47, hasn't been having to many labs. But, we are getting down to work. We're watching Bill Nye videos, taking notes, and learning about matter and physical properties are.
We also have been learning about what the atoms of the three main types of matter, solids, liquids and gasses. The particles of a solid are compact, and have almost no movement other than vibrating in place. The particles of a liquid are more free to move around than the particles of a solid, and take the shape of the container they are in. The particles in a gas take up all of the space available, and are all over where they can be. We learned that the reason you can't walk through solids is because the atoms are so compact. It is hard to move through liquid, because the atoms are spread out enough to allow movement, but still close enough to make it hard. It takes almost no effort to move through gas because the particles are so spread out that they don't push you back to much, but if you go really fast, like 700 miles an hour, you feel air resistance. That is what is we are learning in science class.

The Private Eye


Chart of findings
 
Little square soury salt
Today we got to classify matter by some other physical properties, we got private eyes (jeweler's loop) and took a really close look. A lot of stuff looked really cool. We looked at glue, chicken feed, and salt. Along with two items of our choice, it was a lot of fun. We looked for the shape, size, color, and texture. Our science teacher also had a bunch of cool stuff to look at. He had a wasp nest, spiky tree things, and other things. We saw little rough holes in the salt, I could just taste the sour square in my mouth. When we looked at the mulch it reminded me of cow patties and old decomposed grass. This Private Eye thing is pretty darn EPIC! No wonder the jewelers all use it. We will see ya next time on the SCIENCE BLOG!
