Currently... 10/15 - 10/18

Upcoming Events:

Important Date:   Our Unit 3 test will be October 17th.

 

Unit 2 Vocabulary that will be revisited on Unit 3:

Element, Pure substance, Chemical Symbol, Matter, Mass, Volume, Density, Chemical, Periodic Table, Atom, Substance,  Meniscus

 

Unit 3 Vocabulary:

chemical changes, physical changes, precipitate, atom, molecule, substance, element, compound, chemical reaction, temperature, chemical formula

 

 Tested TEKS for Unit 3:

6.5(A) know that an element is a pure substance represented by a chemical symbol and that a compound is a pure substance represented by a chemical formula

6.5(C) identify the formation of a new substance by using the evidence of a possible chemical change such as the production of gas, change in temperature, production of a precipitate, or color change.

 

Previous Teks revisited:

6.6(B) calculate density to identify an unknown substance

Week of 10/15-10/18

 

I hope students have had a restful and fun extra few days.  This is the list of upcoming events.  Please make sure that if a student was absent on Friday, that they come in the morning to make-up the quiz we had on Friday.  Students need to be studying for his or her Unit 3 test.  Valuable study tools are found in Google Classroom for the unit.

Monday-Student Holiday
Tuesday- Study --any work not completed in class--Quizizz due on Wednesday, 10/14 (found in Google Classroom)
Wednesday- Study -- any work not completed in class  [Quizizz-due]
Thursday- Unit 3 Exam: Changes in Matter
Information to help students study:

Unit 2 Vocabulary that will be revisited on Unit 3:  Element, Pure substance, Chemical Symbol, Matter, Mass, Volume, Density, Chemical, Periodic Table, Atom, Substance,  Meniscus

Unit 3 Vocabulary:  chemical changes, physical changes, precipitate, atom, molecule, substance, element, compound, chemical reaction, temperature, chemical formula

Tested TEKS for Unit 3:

6.5(A) know that an element is a pure substance represented by a chemical symbol and that a compound is a pure substance represented by a chemical formula  

Ex:  Iron is found on the periodic table and is a pure substance represented by the symbol, Fe.

Ex: H20 is made up of 2 pure substances.  The two pure substances or elements are Hydrogen and Oxygen.  H20 is represented by the chemical formula.

6.5(C) identify the formation of a new substance by using the evidence of a possible chemical change such as the production of gas, change in temperature, production of a precipitate, or color change.

Ex: A chemical change occurs when a new substance has been formed.  It is evident by CHOPG. C=color change, H=heat produced (temperature change), O= odor produced, P=precipitate, G=gas produced

Ex: A physical change occurs when a physical change has taken place, but NO new substance is formed. (paper tearing, ice melting, breaking something in two pieces, etc.)

Previous Teks revisited:

6.6(B) calculate density to identify an unknown substance

Given a mass of 100 grams and a volume of 20 mL, solve for density.

Density = mass/volume

Density = 100g/20mL

Density=5 g/mL

Friday- Analyzing our Unit 3 Exam, corrections, and identifying goals (strengths/weaknesses), identifying how we can grow academically from our data.
