1. TOPIC: 4.0 Chemistry LG and SC

2. HAND OUT Learning Goals for this unit Put a check if you “KNOW” the information or “NOT YET” if you do not yet understand the SC UNIT 4: Chemistry LG and SC Know!No t Ye t Vocabulary 4.1 How Does Chemistry Fit In? LG: Understand that chemistry is a microscopic study that creates the macroscopic world  I CAN describe how the building block of biology (the cell) and the building block of Chemistry (the atom) are related  I CAN explain what microscopic and macroscopic mean in relation to chemistry.  I CAN describe how the microscopic influences the macroscopic. Macroscopic Microscopic Atoms Cells Matter particles 4.2 History of the atom LG: Understand that models help describe matter – how it behaves and how it MAY look if we could actually see it.  I CAN describe the progression of the model of the atom through time  I CAN take a given scientist and state what model he created.  I CAN take a given scientist and state the scientific experiment that was conducted in order to create a new model Dalton Thomson Rutherford Bohr Current Quantum Model 4.3 Subatomic Particles LG: Understand that everything is made up of elements and these elements are actually made of specific individual atoms.  I CAN describe each subatomic particle by stating the charge, location, and relative size  I CAN look at an element on the Periodic Table and identify the number of subatomic particles using the atomic mass and number Proton Electron Neutron Nucleus amu Atomic mass Atomic number 4.4 Periodic Table LG: Understand The elements are represented on the periodic table by symbols and these symbols are organized in systematic ways  I CAN identify the various families on a Periodic Table  I CAN describe the main properties of each family Families Group Noble Gases Halogens Transition Metals Metals Non-metals Metalloids Alkaline Earth Metals Alkali metals Inert 4.5 Isotopes and Ions LG: Understand that elements are defined by the number of protons, yet neutrons and electrons can change.  I CAN compare neutral atoms, ions and isotopes by discussing how the subatomic particles change in each.  I CAN deduce how many subatomic particles are in an element from a word problem.  I CAN communicate why the atomic mass is a decimal.  I CAN predict ions based on placement in the Periodic Table (1,2,6,7 columns) Ions Cations Anions Isotopes Net charge 4.6 Bohr Model LG: Understand that the Bohr Model can help us illustrate why atoms react and change.  I CAN draw a Bohr Model for the first 20 elements  I CAN identify where the low energy and high energy are in a Bohr Model  I CAN compare core and valence electrons in a Bohr Model Energy levels Octet Rule Valence Electrons Core Electrons Quantized Energy Shel Bohr Model Principal Quantum number 4.7 Lewis Dot Structures LG: Understand that the valence electrons are where the Chemistry happens – so we represent just the valence electrons in a Lewis Dot Structure  I CAN draw a Lewis Dot Structure for the first 20 elements Lewis structure 4.8 Bonding LG: Understand that elements combine in predictable and specific ways.  I CAN predict the type of bond given 2 elements.  I CAN take a name of a given compound and state the type of bond that is present. Covalent Bond Metallic Bond Ionic Bond compound 4.9 Conservation of Matter LG: Understand that matter is not created or destroyed, only changed  I CAN define the Law of the Conservation of Mass  I CAN balance a simple chemical equation Balanced equation Chemical Equation Conservation of Mass Summative: Lab Report and Exam

3. TOPIC: 4.1 How Does Chemistry Fit in?  EQ: How does Chemistry relate to Biology?

4. Let’s put things in perspective! Let’s start small and go big Let’s start small and big then rewind and go very small!!! (at 6:46 the “Cell” is introduced, at 7:15 the “atom” is introduced) http://youtu.be/vRjGarICal4 http://youtu.be/0fKBhvDjuy0

6. How does the microscopic influence the macroscopic? Example 1 Rub your hands together Describe observations to neighbor Example 2 Blow up a balloon Volunteer rub on hair Describe observations to neighbor What is going on beyond what we can see?

7. In your notes please write these L. side questions and then write your response in the notes. 1. How are the cell and atom related? 2. What does chemistry look like on the macro level compared to the micro level? 3. How are microscopic things related to macroscopic things?
