**Chemistry**

Announcements:  

1. Test:  Tuesday, February 25th. Chemical Bonds

Standards and Benchmarks:

1. EALR4.9-11.PSD: Ions are produced when atoms or molecules lose or gain electrons, thereby gaining a positive or negative electrical charge.  Ions of opposite charge are attracted to each other, forming ionic bonds.   Chemical formulas for ionic compounds represent the proportion of ion of each element in the ionic crystal.  
2. EALR4.9-11.PSE: Molecular compounds are composed of two or more elements bonded together in a fixed proportion by sharing electrons between atoms, forming covalent bonds.  Such compounds consist of well-defined molecules.  Formulas of covalent compounds represent the types and number of atoms of each element in each molecule. 

Big Idea:

1. Various types of chemical bonds exist based on the electronegativity difference of the bonding atoms.
2. The type of bonding between elements, in part, determines properties of the compound. 

Class Outline:

1. Attendance
2. Reading Check: Section 9.3
3. Entry Task  
4. Review Section 9.3
1. Types of Intermolecular forces
1. Dipole-Dipole Forces
1. Bonds formed due to polarized molecules. 
2. London Forces
1. Bonds formed due to instantenous (temporary) dipoles
3. Hydrogen Bonds
1. Bonds with extremely strong dipoles
5. Chemical Bonds Test Review Sheet
6. BrainPop:  Chemical Bonds (If time)
7. BrainPop: Ions (If time)

Homework:

1. TBA  

***Biology***

Announcements:

1. Essay exam on Thursday of this week. 

Standards and Benchmarks (Biology 9-12):

1. EALR 4.9-11.LS1G:  Cells us the DNA that forms their genes to encode enzymes and her proteins that allow a cell to grow and divide to produce more cells, and to respond to the environment. 
2. EALR 4.9-11.LS1H:  Genes are carred on chromosomes.  Animal cells contain two copies of each chromosome with genetic information that regulate body structure and functions.  Most cells dived by a processes called mitosis, in which the genetic information is copied so that each new cell contains exact copies of the original chromosomes.  

Big Idea(s):

1. Organisms reproduce by passing genetic information to their offspring.

Class Outline:

1. Attendance
2. Entry Task
3. Finish Correcting Meiosis / Mitosis Packet (Few questions remaining)
4. Class Time for Homework: 
1. Prep for Mitosis / Meiosis Writing Assignment:
1. Students will have 1 class period to write a ~300-400 word essay on Mitosis and Meiosis.  
2. The essay should demonstrate understanding of:
1. The importance of Mitosis and Meiosis
1. The purpose of meiosis/mitosis
2. The importance of meiosis and mitosis with regards to transferring genetic material. 
2. A description of the stages of each, and the key differences between mitosis and meiosis.
3. The essay will be hand-written in class on Thursday of this week.    
1. Each student may have 1 notecard (front and back) of hand-written notes, with reasonable size print (not less than what would be considered 10pt font)
4. The essay should use appropriate vocabulary, such as chromosomes, chromatids, spindle, centromere, haploid, diploid, etc. 
5. Grading:
1. This essay will count as your TEST over Mitosis and Meiosis.  
2. You will be given a letter grade, A-F, based on how well you have demonstrated and communicated understanding of meiosis/mitosis.  This means not only must you have correct information, but you must communicate it in an organized fashion using appropriate vocabulary.   

Homework:  

1. Essay Exam on Thursday of this week. 

****Life Science****

Announcements:  

1. Entry task notebooks are now kept on the shelf at the back of the room.  They need to be put away NICELY at the end of each period. 

Standards and Benchmarks (Life Science 6-8):

1. EALR 4.6-8.LS1C:  Multicellular organisms have specialized cells that perform different functions.  These cells join together to form tissues that give organs their structure and enable organs to perform specialized functions within organ systems.
2. EALR 4.6-8.LS1C:  Describe the components and functions of the digestive, circulatory, and respiratory systems in humans and how these systems interact.  

Big Idea:

1. The respiratory system is composed of cells that form various tissues that aid in the breathing process.
2. The circulatory system is composed of various organs and cells that are responsible for transporting blood and nutrients throughout the body.  

Class Outline:

1. Attendance
2. Entry Task
3. Finish Video:  Pushing the Limits:  Strength
4. Return Test & Review
5. Introduce:
1. Digestive System
2. BrainPop:  Digestive System

2. Game: Guts and Bolts

Homework:

1. TBA

***Trigonometry***

Announcements:

1. n/a

Standards and Benchmarks:

1. CCSS-GSRT.1
2. Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute triangles
3. CCSS-GSRT.7
1. Explain and use the relationship between sine and cosine of complementary angles.
4. CCSS-F-TF
1. Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle.  

Big Idea:

1. Fundamental math skills are the building blocks upon which trigonometric skills are built.

Class Outline:
