Acids and Bases Pt. 2 - 5/14/17


Summary:
Let's review some things, the pH scale tells us how basic or acidic something is. The pH scale ranges from 0 to 14. Acids have a pH ranging from 0 to 6.9. The lower the pH, the stronger the acid. An acid that has a pH of 6 is weak while an acid that has a pH of 1 is strong. Bases on the other hand have a pH ranging from 7.1 to 14. With bases however, the lower the pH, the weaker the base.  A base that has a pH of 8 is weak while one that has a pH of 13 is strong. So what's in between? Neutral substances have a pH of 7. The most known example would be water. Acids have a sour taste, while bases have a slippery feel. Examples would be lemon juice and soap. Acids turn a litmus paper red and bases turn litmus paper blue. A litmus paper tests a pH of a substance. A cool thing to know as well is that it is better to drink acidic things (lemon juice) rather than basic things. Most basic things can be poisonous to humans (oven cleaner).

S&EP: Arguing From Evidence:
Even though there were no experiments or debates with the class, our table had a few discussions over the week about different things. As we have been doing lately, we play the legends of learning games, this time however, we focused in on the topic of the environment to help us for the science portion of the end of the year project. When there were questions we didn't know the answer too, our table would have discussions of which answer was right and why, as well as using the process of elimination to figure it out. By using this process, my team and I were able to play the game successfully, as well as learn new things in the process.

XCC-Cause & Effect:
The Environmental Accords are 21 different policies, that would make the city or the community you live in sustainable, clean, and a better place to live. Already you can tell how this has a cause and effect relationship.  Each specific policy has a direct result. The Accords are divided into energy, waste reduction, urban design, urban nature, transportation, environmental health, and water each hoping to better the environment. For example, one of the accords states that there should be a plan to reduce usage of electricity by 10% in seven years. This helps save money, benefit the economy, and will be eco-friendly. Another policy states that creating a rule that prevents waste from entering landfills by 2040 will lead to less methane gas produced slowing down the heating of the earth. These accords helped show me that there are plans set in place to make your community environmentally friendly.

Multiplier:
This week I was learner, this was because I made sure I knew a lot about the topic we were learning for future reference.

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...
