1. 2.1 The Nature of Matter LT: Today I will…
Identify the three subatomic particles found in atoms
Describe the two main types of chemical bonds
Word
Atom
Nucleus
Electron
Proton
Element
Compound
Ionic bond
Covalent bond
Valence electrons
Entry Task: grab a text book and a copy of the people search from the front of the room.

2. FQ: What are atoms and what are they made of?
ET: take out your vocabulary flipper from Friday. Review all the terms.

3. Atoms: Smallest building blocks of matter
Atoms are the building blocks of elements. They are made of 3 sub-atomic particles
Protons
Neutrons
Electrons

4. Sub-Atomic Particles

6. Elements and Compounds
Pure substances composed of only one type of atom
Compounds
Pure substances composed of two or more elements, chemically combined, in a set ratio/proportion.

7. Valence Electrons
Electrons located in an atoms outermost “shell” that are used to bond with other atoms
Bonds can be with atoms of the same element like O2 or can be with other elements like CO2

8. Chemical Bonds
Ionic Bonds: Give or take electrons

9. Chemical Bonds
Covalent bonds share electrons

10. EXIT TICKET Draw a basic atom and include the following
The 3 different sub-atomic particles
The charges next to those particles
Note: the number of each does not matter

11. Homework Read section 2.3 Take notes on the following What is a…
Protein
Carbohydrate
Lipid
Nucleic acid

12. Friday 11/11 - 2.2 Properties of Water
LT: Today I will…
Explain polarity
Explain what makes a water molecule polar
ET: What is responsible for the making and breaking of chemical bonds? Please explain your answer
Your POGIL is your notes for this section and should be in your notebook

13. 2.3 – Carbon (organic) Compounds
ET: What elements does carbon bond with that make up life’s molecules?
Lt: Today I will…
Describe the unique qualities of carbon
Describe the structures and functions of each of the four groups of macromolecules

14. Why Carbon?
4 valence electrons – easily forms covalent bonds with other elements
Bonds with other carbons
Can form large complex structures

15. Macromolecules (large molecules)
Monomers – smaller units that, when linked together, form larger molecules (macro).
Polymers – a macromolecule formed from linked monomers
The monomers may be identical or they may be different

17. Carbohydrates The main source of energy for living things
Monomer: Monosaccharide ex. Glucose
Polymer: Polysaccharide ex. Starch

18. Lipids Store energy, biological membranes, waterproof coverings
Monomers: Glycerol and Fatty acids
Polymers: Triglycerides
Saturated VS. Unsaturated Fats
Lipids

19. Nucleic Acids
Store and transmit hereditary, or genetic, information (DNA).
Monomer: Nucleotide
Polymer: DNA

20. Proteins
Proteins control the rates of reactions, regulate cell processes, and transport substances into or out of the cell
Ex. Enzymes are proteins that do “stuff”
Monomer: Amino Acids
Polymers: Polypeptides (peptide bonds)

21. In your body…

22. Enzymes and Chemical reactions
ET: Get your conclusions out and be prepared to share them.
Write down the following words and leave room to add definitions in your notes
Activation energy
Reactant
Product
Enzyme
Substrate
LT: Today I will
Explain why enzymes are important to living things
Identify the parts of a chemical reaction
Explain what chemical reactions do

23. Enzymes: Speed up chemical reactions by reducing the energy needed to start the reaction. (lower the activation energy)
Catalyst

24. Enzyme/Temperature Lab
Will work with a bin at table groups *except hot plate groups
Clean up: rinse out graduated cylinders in the sink
Safety: goggles

25. Quiz Tomorrow on organic compounds and enzymes
Enzyme Structure
Quiz Tomorrow on organic compounds and enzymes

26. Chemical Reactions Produce new substances by rearranging atoms
Parts of a chemical reaction = Reactants and Products
NA + Cl NaCl
Sugar + flour + eggs

27. Homeostasis Maintaining a constant internal environment
How does your body do this?
It uses a process called FEEDBACK
2 types of feedback are
Negative – works to maintain a baseline level
ex. Your every day stuff like maintaining temperature
Positive – works to push way passed a baseline level
ex. Rarer events like child birth

28. Lab Question: At what temperature does the enzyme catalase work best?
The reaction
Why? Our cells produce a lot of this when they are carryout regular cellular function as a waste product so we have to get rid of it
