Cell Division - 9/16

Summary: Cells growing and dividing is known as cell division or mitosis. There are few steps to this process, the steps are interphase, prophase, metaphase, anaphase, telophase and cytokinesis. Interphase is the processes were cells grow, copy their DNA, and prepare for division. Prophase is were the cell's chromatin condenses and turns into chromosomes. Metaphase is the step were the chromosomes line up across the center of the cell. When anaphase occurs, the centromeres split and the chromatids separate. During telophase a nuclear cover forms around the chromosomes. At the final step, cytokenisis, the cytoplasm splits moving organelles into the new cell. The DNA is copied before mitosis occurs to insure the new cell has the correct genetic information.

 S&EP 4: I used a flip book to to display and analyze data. We drew the steps of mitosis slowly changing. This helped with the understanding of mitosis as you can see the small changes the cell makes in it's development of turning into two cells. Also I recognized patterns in data and saw relationships between variables. For example, I observed that the centromeres in most steps was either moved do a different spot or looked different, but I knew it was always there.

 XCC: Stability and Change: The cell goes through a special change in it's lifespan, mitosis. The cell is contentiously changing until it splits and becomes two cells. First it must copy it's DNA so the daughter cell has the correct genetic information, then it goes through interphase, prophase, metaphase, anaphase, telophase and cytokinesis. Depending on the animal/plant the cell is in the cell cycle can take from 100 minuets to 24 hours to complete.

 Multiplier: This week I was a creator as I had to make my own flip book and I had to be confident in my self of what I was putting down on the the flip book was correct.

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
