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...

Summary:  Galaxies come in three different forms, spiral, elliptical, and irregular. Spiral galaxies have a distinct winding or twisting shape. The Milky Way galaxy (above) is an example of a spiral galaxy. Elliptical galaxies have more of a spherical shape and look similar to circles. Irregular galaxies look unique compared to spiral and elliptical galaxies, hence their name. Irregular galaxies appear misshapen and lack a distinguishable form because they are within the gravitational influence of other galaxies close by. During nuclear fusion, four hydrogen atoms fuse into one helium atom. This makes hydrogen the most common chemical element in stars. When the core of a star starts losing Hydrogen, the star begins to collapse. Black holes form from the collapse in the core of a supernova. S&EP: Analyzing Data:  I used tables to display and analyze data on different planets, noticing the differences and similarities between them. I no...

Summary : Stress takes a variety of forms. Some stress happens as the result of a short-term event such as having an argument with a loved one. Other stress happens due to recurring situations, such as working a demanding job. When recurring situations cause stress that is both intense and sustained over a long period of time, this is known as chronic stress. Even though all stress triggers physiological reactions, chronic stress is a big problem because of the significant harm it can do to the body and the brain. When someone experiences a stressful event, an area of the brain that contributes to emotional processing sends a distress signal to the hypothalamus. This area of the brain functions like a command center, communicating with the rest of the body through the nervous system so that the person has the energy to fight or flee. This “fight-or-flight” response is responsible for the physical reactions most people correlate with stress including increased heart ...

15) What type of tide would this arrangement of earth-moon-sun create?  My answer: Spring tide. Correct answer: The correct answer is spring tide. This is the correct answer because when the moon and sun are aligned, they combine their gravitational pulls. This is also why spring tides have the biggest difference between the high tides and low tides. On the mastery quest, this answer was marked wrong even though it was correct. 17) Why do we experience the changing of seasons on the earth? My answer: Rotation of the Earth Correct answer: The correct answer is the tilt of the Earth's axis because when the Earth revolves around the Sun, the axis affects the position of the northern and southern hemispheres in relation to the sun, which causes a change in the seasons. 37) What is your science teacher's full name?  My answer: Mariana Garcia-Serrato Correct answer: The correct answer is Mariana Garcia Serrato. This is the correct answer because in all other ...
