Atoms,Elements and More 3/19/17

Summary: Atoms are the basic build blocks of matter.  Atoms are made up of protons, neutrons, and electrons. Protons have a positive charge, while neutrons have a neutral charge, and electrons have a negative charge. You know something is an element if it is a pure substance, made of one atom, and is on the periodic table. While a compound is a combination of two different types of elements. A molecule is two or more of the same type of atom. A molecule can be an element or not. Now it's time for matter, matter is something that has mass and takes up space. Matter can be a solid, liquid or gas. Matter is indivisible and indestructible. All the matter in the world is only made up of about 100 different elements in various combinations. The human body is only made up of about six elements however.

SP5: Using mathematics and computational thinking: I expressed relationships between variables by writing mathematical equations. For example, I calculated the density of the crown that matched the density of gold when we had the assignment of the density dilemma. I had to figure out which crown was made of gold by matching its density to gold. The way I did this was by  taking the crowns mass, which was 3474 g and divided it by its volume, 180 cm3. This got me a density of 19.3, which is the same as gold.

XCC Scale Proportion and Quantity: In atoms, there needs to be a stable/equal amount of protons, neutrons and electrons. If you had more than 1 or less than the other you would have an unstable charge. Which is a bad thing for the atoms as it would have to emit nuclear radiation. The amount of protons neutrons and electrons being equal are very important. As well as the amount of protons, neutrons, and electrons define the atom and make it unique.
This week I was a learner, this is because this is a new topic that I am not an expert on so you always learn new things.

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
