Summary: Macromolecules are organic compounds that contain carbon. The elements found in these compounds are carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. There are four macromolecules, lipids, carbohydrates, nucleic acids, and proteins.  Lipids store energy and they make up most of the cell, some examples are things like fats, oils, and waxes. They are made carbon, hydrogen, and oxygen. Carbohydrates are the ones that give you energy. They are made of carbon, hydrogen, and oxygen. Proteins regulate growth, development, and transport oxygen and other substances. There made from carbon, hydrogen, oxygen, nitrogen, and sulfur.  Nucleic acids are the instructions for the cell. They are made of carbon, hydrogen, oxygen, nitrogen, and phosphorus. The two examples of them are RNA and DNA.

SP2: I used the photosithesis lab to test different variables to see what would produce the most oxygen.  The light intensity, the CO2 surrounding a plant, the temperature and the color of the light all contribute to a plant making as much oxygen as possible. I figured out that farmers should always know what the best conditions are for a plant to grow. So the plant can produce the most oxygen by making it from the waste product to the creation of glucose, or sugar, the plants food.

XCC Cause and affect: Plants and trees make oxygen, but not on purpose. In a process called photosynthesis, the plant is making food in the chlorophyll. When it is making glucose or sugar, the waste that comes from it is oxygen. When we breathe in we take in that oxygen and breathe out the carbon that is used in the process of making glucose. Without one or the other, the system would fail which is why its so important that we keep plants alive and well and give them what they need to mass produce oxygen.

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 Am...

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 befor...

The Designer Species Project - Project Blog 11/5/17

Summary: The Fobra is a new species of frog with the body of a red-eyed tree frog, the eyes of an owl, the fangs of a king cobra, and the claws of a squirrel. Since the fobra lives in planet C, a tropical planet with much rainforest and vegetation, our frog can "nest" itself in the plants to stay warm. To stay cool the fobra can soak itself in puddles and absorb the moisture. The fobra is also a warm-blooded animal. The fobra uses both its tongue and teeth to eat, depending on the size of animal it is eating. With the claws similar to squirrels, the fobra will be able to get away and climb up on trees faster, making predators unable to get it. As well having the bite similar to the king cobra, our species will bite predators when it feels threatened or scared by predators that are after them. The fobra will be able to strike extremely quickly, like a cobra, in self-defense. Red-eyed tree frogs will lay clutches of eggs on the underside of leaves that are standing abo...
