Chemistry
Today in class, we learned what our earth is made of, how the earth’s landscapes were made, and how to make rocks.
First, I learned that the earth is made up of several different layers, with their own materials. The crust is made out of solidified mantle, which is made out a thick liquid called silicate(which is a salt molecule that contains silicon and oxygen). The outer core is made up of liquid iron and nickel. Also, that’s the place where we get all the material we need to make coins and other metallic things. And finally, the inner core is also made of iron and nickel, but it is a very hard solid. Another interesting fact I learned today was that all of the earth’s landscapes were made from earth currents. Earth currents are currents under the earth that go around the earth and mix hot elements with cold elements, which eventually go up in the ground to create mountains. Finally, I learned how to make my own rocks. First I got carbon and water, and then I combined them together into a flask. Next, I then put some piece of calcium chlorate( which is a salt of chloric acid) inside, and waited for the magic to happen. A few minutes later, rocks were sprouting up from the pieces of calcium chlorate. Bubbles were being made in the water, going up and up, while making a very strange veiny track behind it.
