Background Research
Core: Made of solid iron and nickel. Earth's magnetic field (also known as the geomagnetic and magnetosphere) is the magnetic field that extends from the Earth's inner core to where it meets the solar wind, a stream of energetic particles coming from the Sun. The earth uses that to stop solar winds and most of the radiation from the sun. Outer Core: Made of liquid metals, like liquid iron and nickel. Silicates: Combination of silicon (si) and oxygen (o). 95% of earth's crust, and 97% of earth's mantle is made of silicates. When silicates in the mantle bond with the metals in the outer core, it produces metal silicates. Mantle: Made of molten rocks (silicates). That's where the molten metals meet with other things like silicates4. Crust: The outer, solidified mantle Earth = apple Crust = skin of the apple Chemistry: Silicon to Rocks
First, we poured the solution of 100 ml of sodium silicate and ionized water into test tubes. At the end of pouring, the solution of sodium silicate and water was in roughly a 2:3 ratio. Then we poured calcium chloride into one test tube. We had to be careful not to touch it because calcium chloride is a mild base similar to lye so it could burn your skin. Next, we poured cobalt chloride into a test tube, it started out as this red-purple color but then it turned into purple, green, and blue The little formations that took place at the bottom started releasing little strings of it to the surface of the water. Then Andrew added copper sulfate to another test tube, the color of the formation at the bottom was blue. At first, it didn't work that well but after a couple of minutes the pointy, bubbly things started to form. Reflection: I really didn't know what I expected from this lab, but it turned out to be pretty cool. It was really informative, and the way it looked at the end was pretty cool.
