Summary:  The cell is the basic unit in life. All living things are composed of cells.  The way you know things are alive are if they reproduce, grow, need nourishment and the respire. Most organisms are made of multiple cells, but there are single celled organisms such as bacteria.  Cells are made up of pre-existing  cells which is how you know they reproduce.  The cell is made up of many parts called organelles which helps the cell function properly. There are many organelles, such as lysosomes, peroxisome, cell membrane, mitochondria, vacuole, ribosome, and Golgi body and more.

S&EP 6: I explained how atoms and cells are different in a worksheet in class. I explained how cells are the 'building block' for life while atoms are the 'building block' for everything. I used evidence that I learned in fifth grade to answer my questions. I also had to decipher which one out of a group of things was the odd one out and why.

XCC: Systems and System Models: When you think about it, the whole body works together as a system, without one piece the whole system would fall apart. Like how cells are a system of organelles working together and when you have enough cells you can make tissue and after they become tissue, they become organs and enough organs create a living thing.

Amedeo Avogadro - 5/27/18

Image
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
