Motion - Scalars and Vectors | 12/3/18-12/7/18

Cube by DynaBlast
Summary:

       Motion can be described in two different types of quantities, scalar and vector quantities. Scalar quantities are quantities that only have a magnitude or size. Vector quantities are quantities that have both a magnitude and an associate direction (also known as a magnitude direction). One example of the difference between scalar and vector quantities are distance and displacement. Distance, a scalar quantity describes the amount an object has traveled. Displacement however, is a vector quantity and it expresses the distance between the origin and destination of an object in the shortest interval or distance possible. Displacement also describes the direction of a straight line from the origin to the destination. An example of distance is that the person ran half a lap around circular track that is 400 meters, meaning that they ran 200 meters. An example of displacement would be that the distance from one end of the circular 400 meter track to the other is equal to the diameter of the circle, which is less than 200 meters (the distance). Meaning that the displacement is just about equal to 127 meters East (the direction of the origin to the destination).

S&EP 2-Developing and Using Models:

       I developed and used a model this week in science when creating a foldable that helps build understanding of scalar and vector quantities. The foldable consisted of the definitions of scalar and vector quantities, examples of scalar and vector quantities, and lastly, an illustration of one of the examples of scalar and vector quantities. Some examples of scalar quantities are distance, mass, volume, length, temperature, and speed. Some examples of vector quantities are displacement, velocity, acceleration, force, weight, friction, and momentum. The illustration that I created for scalar quantities was a picture of a cube with measurements and its volume listed below. The illustration that I created for vector quantities was a picture of the example given above about distance and displacement (except in this case I only described the displacement part) with a circular track. Although, in my illustration I used different measurements so the displacement was not 127 meters.

XCC-Energy and Matter:

       The system that I identified this week in science that relates to energy and matter is the system of motion. Energy and matter are related to motion due to how motion would not even exist without energy and matter. Energy is required due to how objects are put in motion with some type of energy being used. As for matter, well matter is what makes up objects. Also, without objects, there would be no need for motion because their would be nothing that could be moved. This is how energy and matter are related to the system of motion.

Systems In a Human Body Info Paper 10/15/15

Friday and Monday we were writing down the definitions of (I believe) organelles that are part of the urinary and digestive system. Here are some examples of some of the organs my class had to write down the definitions for, the esophagus, the pancreas, the liver, the small intestine, and the large intestine. One thing that I forgot to add is that there was one other paper that had the definitions down for my class because I did not want anybody thinking that my teacher would make us write the definitions on our own out of the blue. The way we knew the definitions was because on Thursday or Friday I forgot which day any ways my teacher showed what every organ that we had to write the definition for what each organ did in order. But the fun part was she assigned every single person in my science class an organ to make it fun. What also helped was that Ms. J went over the answers with my science class also she allowed ...

Chemistry Mastery Quest 2 Regrade

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

Plate Tectonics 3/10/18

Image
Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges...
