Summary

This week in science we learned about matter and atoms through various activities like taking notes, a gizmo, and completing a doc. I learned that most of the weight of an atom is in the nucleus. What makes up the nucleus is neutrons and protons and the electrons are left on the outside. Also that in the space between the electrons and the nucleus their is absolutely nothing there to fill that space. I also learned what density is, it is how close an objects atoms are together and how much stuff we have in a given space. Or as most people put it mass divided by volume equals density. llAnother thing I learned was a good definition for molecules, compounds and elements. A molecule is when 2 or more atoms are chemically bonded, a compound is when two different atoms are chemically bonded, and an element is when one pure atom makes up a substance. Also that all compounds are molecules but not all molecules are compounds.

S&EP 4-Analyzing and Interpreting Data

I analyzed data and interpreted data through the triple beam balance gizmo. I had to find data like which objects were over 300 grams and how much each object weighs and had to put it into a table. I got the data through using the triple beam balance. The data really helped me understand how data can be found through experiments because before this I had never done an experiment where I had to do it all by myself with no help.

XCC- Systems and System Models


The system and system models I used were the triple beam balance gizmo. The parts of the triple beam balance are the measurement tray, the 1 gram rider, the 10 gram rider, the 100 gram rider, and the pointer. The parts of the system work together by if one rider can't find the weight of the object then you use another rider and maybe even another rider to help balance out the pointer. After that they work together because when the object is balanced you then have to add up where each rider is to find the weight of the object. The limitations to this system is that the max weight the triple beam balance can find is 610 grams. The function of the system could be better by maybe having something electronically tell you if the object is balanced instead of having to use a magnifying glass.

Multiplier

This week I was a learner because I didn't at first know how to do the chemlink assignment or how to use the mass and volume gizmos. But that didn't stop me because I really wanted to learn so I asked my friends and Mrs. Garcia for help when I needed asking things like,"how does this work" or "where can I find this." I consistently asked questions so I could learn to the best of my ability.

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

Image
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...
