Thursday's Reviewing Class

Today, May 27th, our class was about reviewing things from Chemistry Unit for our final exam. First off all, Ms. D asked us to go Dr. Heslips office. There we took some pictures and later visited Dr. Haddons balcony to take a picture with Mr. Houlis. After taking some lovely images, Ms. D and us returned to the classroom. There we started discussing exercises that were on the chemistry quiz we took Tuesday, May 25th. Here is the list of the exercises including the answers and the notes we took with Ms. D.

Protons vs. Electrons

Proton is a stable particle with positive charge equal to the negative charge of an electron. It is also found in nucleus and it is made from quarks.
Electron is an elementary particle with negative charge. It is also spinning around the nucleus. It can also be found in a lightning.

Matter vs. NRG

Matter is anything that takes up space or anything that has mass.

NRG is not matter, it is an ability to do work or cause change.

*Mass vs. Weight

Mass is the amount of matter inside an object. Uses kg or g as units. It also stays the same.

Weight is the amount of force put on the object by gravity. Uses newtons as units. It also changes itself depending on the position. (Ex. On the moon, on the poles.)

Solute vs. Solvent

Solute (dissolute) is a mixture that is added to the solvent, where the solvent dissolves it. The process is called a chemical change. (Chemical change – a change in matter that produces one or more new substances.)

Solvent (dissolvent) is a substance that is mixed with the solute.

(Ex. Cedevita: solute = powder, solvent = water)

Homogeneous vs. Heterogeneous

Homogeneous mixture is a mixture where you can’t see the different parts. (Ex. Alcohol.)

Heterogeneous mixture is a mixture where you can see the different parts because everything is grouped up. (Ex. Sperm.)

*Capacity vs. *Volume

Capacity is the amount of matter an object can contain.
Volume is the amount of 3-dimensional space occupied by an object.

*SI is the metric system that measures them. Here is the list of some other chemistry-related vocabulary words.

Shape a 3-dimensional geometric shape.

States of Matter a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary.

Molecular Motion the movement (average) of particles in a state of matter.

Molecular Proximitydistance of particles in a state of matter.

Last thing Ms. D said is the relation to today’s world; if someone would solve the Filament state of matter, and make it be together and stay for more than one second, that person would create a whole new type of energy, more efficient one. So, that means that no more oil or gas needs to be spent. After the long reviewing session, Ms. D showed us the assignments for homework, located on Moodle.

Due Friday, May 28th:

1. The 7th Blog Comment. Remember, you must have three 8th grade comments, three 7th grade comments and two 6th grade comments.

2. Color in the TWO Periodic Tables in your packet - be sure to read the directions for what you need to do for each.

  1. Hi Severyn,
    I think that you could have checked your grammar a bit for this - you are missing "a" and "the" in front of some nouns. You could have made the font bigger at the end, as well. The link to Moodle is helpful! Except for that, this post has good information and I understood what you were doing in class.

  2. Severyn - after a bit of difficulty, I am glad your Scribe Post has come through. You have written about most of what we covered during class, but some of your scientific information is incorrect - especially with mixtures vs. compounds. Make sure you understand the differences between these two things as they will be on the Final Exam. Your spelling looks great, but your grammar in many places makes this difficult to read, Your opening picture is great, but the font next to it is almost missed by the reader. You have a great looking chart on the States of Matter. I think a few more links or pictures would have added to this post. Your real-life relationship is clear and well done. Overall, nice work! ~Ms. D.
