Mud & Water

We did something really cool in our last experiment because we got to play with mud and water. We set up a stream table with some dirt and elevated it with 3 text books on one side, then we poured water out (I think it was 24 oz what ever a Gatorade bottles are). We then recorded the width at the middle of the channel the water made. The erosion was really interesting.

The earth that we live on is, in a way, divided into different parts. all the different plates is the reason why the earth is split up. There is different types of plates. Some plates crash, some slide, and some move away from other plates. Some island have split in half and others have come together with other islands or even whole continents. Around the plate boundaries is where a lot of earthquakes and volcanoes happen because the plates our crashing, or sliding underneath each other. Usually, new land is found where the plates have moved away from.

There are a few kinds of earthquake waves on our planet one S waves and P waves.
P waves that can travel through solids even water and are the first wave.
S waves are second and can only travel through solids not water.

In class we learned that the earth has two heat sources, the primary being the sun, which gives it energy through the form of radiation entering the atmosphere, and becoming convection, partially, and the rest of the energy reaches the plants, they receive that energy, and use it to scrub the air of its CO2, and put it into various carbon stores, which provides the rest of the food chain a basis of life. Carbon, the basis of pretty much all life on earth comes from carbon, amino acids, and H2O, or water. when a rabbit, or other vegetarian eats plant matter, they receive carbon stores in an interaction of matter, and energy, an energy transformation, like when you charge a battery, electricity converts into chemical energy, to be stored by the battery, for use by people. the other form of energy that the earth has is convention, in the mantle, and core of the earth, which works like a lava lamp, the magma rises, cools, then falls back down, or, if its hot enough, will burn through the crust, in the form of volcanic activity

Temperature density

From doing some experiments in class, I learned about how heat affects density.
I learned that when a liquid or gas is heated, the molecules spread apart and take up more space, which makes them less dense. I also learned that cold water is more dense than hot water.
One experiment that Mr. G did was heat a ball and stick it through a hole in a rod. When the ball wasn’t hot, it went through the hole. Once it was hot, however, the ball did not go through. This happened because when the ball was heated the molecules started moving around a lot, fast, and needed more room which made the ball expand. The mass/weight of the ball stayed the same but the volume/size had increased.

float your boat

Our team did how the size of the walls affects how much it floats.
As we increased the size of the walls we will count each pennies. Our results were that for boat one held 31 pennies boat number two held 34 pennies, boat number three held 37 pennies, boat number four held 27 pennies. The reason why this happened was because the walls cannot hold up before it sinks but by the last one the mass was smaller and so it would sink more. Our guess was sorta right we were right at first but after a while it became wrong our highest data point was boat number three at 37 pennies boat number four got 27 pennies. We had no problems. What would happened if we used salt in the water?

Weathering is The break down of materials by Air, Water, Plants, and Animals. Erosion takes stuff and washes it out. As you may be able to tell this kind of thing can have a negative affect on a lot of things. My team tried to think of a way to protect framers from their farms getting eroded. One of the things they can do is manage live stock grazing to prevent overgrazing.

In my group We had the Coniferous forest, Also It is called the Taiga, I also Learned that Their is a lot of rainfall, warm summers and lots of other stuff. I really like other peoples video, they where really creative. I kinda which we could do it again so I could make our video better.I also learned that the desert has only cactus, as plants, all the Biomes are, Tropical rain forest, Desert, Chaparral, Deciduous, Tundra, Savana, Polar, Grassland, Taiga, and Ocean.

In Mr. Gonzalaz's class we had a baking soda and vinegar lab. In are group we decided to add more baking soda each time we did the experiment. We did it three seperate times and each time the circumference of the balloon over the tube increased. Are results of my teams experiment were that each time we added more baking soda and that way balloon size increased. Our prediction was correct.
