Plate Tectonics 9/20/15-9/27/15

Summary

This week we continued our research on plate tectonics. At the beginning of this week we had to create a clay model of the earths layers. But since it's clay we could use it for experiments right away we had to let it dry a bit. So in the middle of the week we learned about a man named Alfred Wegener. We learned that he was the first person to ever believe that the earths continents were once all bunched up together,but no one believed him and said he was crazy. Then near the end of the week we used our model that we had made and pushed them just a bit uneven so it would be what it looks like when their is an earthquake. Then we went around measuring all the gaps between where it was before and where it is now.

I built my model as I learned about plate tectonics. Plate tectonics are a very interesting and important thing to know about. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. When I made my model I wanted it to represent the earths interior and what happens when it splits apart like when it does with an earthquake and how plate tectonics move.

Amedeo Avogadro - 5/27/18

Summary : Amedeo Avogadro was an Italian scientist who created what is now known as Avogadro's law. Known as a founder of the atomic-molecular theory, he was the first scientist to realize that elements could exist in the form of molecules rather than as individual atoms. His biggest contribution to science, Avogadro’s law, states that equal volumes of gasses under the same conditions of pressure and temperature will contain an equal number of molecules. Amedeo Avogadro was born on August 9th 1776 to Filippo Avogadro and Anna Maria Vercellone. Coming from a family of lawyers, Advogadro was guided to a legal career, and became a bachelor of jurisprudence in 1792. Despite a successful legal career; Avogadro has started private studies of mathematics and physics, which then he pursued full time. SP8 - Communicating Information : This week, I communicated information in the form of a wanted poster about a certain scientist. I decided to create a wanted poster about Am...

Roller Coaster Project Blog - 2/18/18

Summary : A roller coaster ride is a thrilling experience which involves a lot of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor which exerts a force on the train of cars to lift the train to the top of a vary tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation. At the top of the hill, the cars possess a large amount of potential energy. Potential energy is dependent upon the mass of the object and the height of the object. As the cars descend the first drop they lose much of this potential energy in accord with their loss of height. The cars subsequently gain kinetic energy. Kinetic energy is dependent upon the mass of the object and the speed of the object. Therefore, their original potential energy is transformed into kinetic energy. Backward-Looking:  How much did you know about the subject befor...

The Designer Species Project - Project Blog 11/5/17

Summary: The Fobra is a new species of frog with the body of a red-eyed tree frog, the eyes of an owl, the fangs of a king cobra, and the claws of a squirrel. Since the fobra lives in planet C, a tropical planet with much rainforest and vegetation, our frog can "nest" itself in the plants to stay warm. To stay cool the fobra can soak itself in puddles and absorb the moisture. The fobra is also a warm-blooded animal. The fobra uses both its tongue and teeth to eat, depending on the size of animal it is eating. With the claws similar to squirrels, the fobra will be able to get away and climb up on trees faster, making predators unable to get it. As well having the bite similar to the king cobra, our species will bite predators when it feels threatened or scared by predators that are after them. The fobra will be able to strike extremely quickly, like a cobra, in self-defense. Red-eyed tree frogs will lay clutches of eggs on the underside of leaves that are standing abo...
