Summary - This week I learned about Soil. There are two types of soil treatments - plant and trench. Trench makes the soil shape like a staircase while plant keeps it as a firm,flat surface as the plant roots hold the figure of soil together. There are  also different soil types. A few types of soil are silt, sand, and a mixture of both. We used virtual explorations to learn about soil texture and type, and more. I also learned about carbon footprints. A carbon footprint is the amount of carbon and other compounds let out due to the utilization of fossil fuels. Soil has different layers called horizons. Topsoil is the top layer aka the A horizon, and is made up of decomposed materials. The next layer is the subsoil aka the B horizon, and it is  made up of clay, mineral deposits, and less decomposed materials. The layer below is the C horizon. It is made up of a little unbroken rock and very little decomposed materials is in this layer.

SP5 - I used math when I tried to find the carbon footprint of all of my and my groups supplies. We had to do calculations to find the amount of products we needed to make to 1000 kg of the supply. We had wrong calculations, but we still used math for it. We also used math to calculate the distance from where ever the supply was coming from to San Jose. For some people, they had to do it by boat so they also had to find the closest port and things like that.

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

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
