Weekly Blog 10/5 - 10/9 - Volcanoes Unit

www.blastr.com


 Summary: 
In this science unit, we (the class) are learning about volcanoes. Volcanoes are usually formed from "hot spots" in the Earth's continental or oceanic crust(s). Those spots begin to grow and form. The magma inside the volcano has actually come from mostly parts of the Earth's mantle. There are four main types of volcanoes. There is Cinder cone volcanoes,Shield volcanoes,composite volcanoes and Dome volcanoes. As they are all volcanoes they all look different and erupt differently. Like a Dome volcano is one of the interesting ones (in my opinion) because Dome volcanoes function in which their magma is pushing out of the volcano. That is because hardened magma is staying above the magma. Once the magma and other gases push hard enough, that pressure destroys most of the rock bits and flings them into the air. With the magma traveling upward, the volcano will seem to have erupted.
Science And Engineering Practice: SP2: Developing and using models: Earlier this week (Monday) my table-mates and I got to see how cinder cone volcanoes function. First, we put a tube with baking soda or salt into the inside of the volcano. Then, someone had to pour a liquid into the tube and then cap it quickly. If we waited long enough and timed it correctly, the experiment would've ran smoothly. We will see the cap pop off while the vinegar liquid is pouring out. That is how dome or cinder cone volcanoes work. Those two volcanoes are actually similar, judging their actions. Both of them push against some kind of pressure that is holding the magma down.

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 Amedeo

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 before we

Wave Communication - 3/25/18

Image
Summary : There are two types of signals, analog and digital. An analog signal changes in frequency and amplitude all the time in a way that matches the changes in the voice or music being transmitted. A digital signal has just two values, which we represent as 0 and 1. An analog signal varies in frequency and amplitude. A digital signal has two values, 0 and 1 (or ‘on’ and ‘off’). The signal is converted into a code using only the values 0 and 1. The signal becomes a stream of 0 and 1 values. These pulses are added to the electromagnetic wave and transmitted. The signal is received and then decoded to recover the original signal. Both analogue and digital signals can pick up unwanted signals that distort the original signal. Digital signals can be cleaned up in a process known as regeneration because each pulse must be a 0 or a 1, so other values can be removed. Analogue signals can be amplified, but the noise is amplified too. This is why digital signals give a
