ESSENTIAL QUESTION: How do we name compounds?
RELEVANCE: What’s in a name?
NGSSS: SC.912.P.8.7; MAFS.912.N-Q.1.1; LAFS.910.WHST.1
LEARNING OBJECTIVES: Students will be able to:
-explain the significance of a chemical formula and the meaning of symbols and subscripts.
-determine the formula and the name of an ionic compound formed between ions including binary, transition metals and polyatomic ions.
-write and name molecular compounds using prefixes.
-continue quarterly project how does pH affect plant growth.
BELL RINGER: rewrite the recipe OR Kahoot Balancing Equations
SUPPLIES/TECHNOLOGY: white board and markers, computer(s) with internet access, LCD projector, glue, scissors, rulers, highlighters, calculators
VOCABULARY: molecule, monatomic ion, polyatomic ion, subscripts, prefix, diatomic molecules, oxidation numbers, anion, binary, cation, formula unit
HOME LEARNING: HL 1 Balancing Chemical Equations
AGENDA
WHOLE GROUP
We reviewed the focus calendar objective for the two week period.
The bell ringer was to rewrite the recipe or do a Kahoot on Balancing Equations. You can find the recipe bell ringer below.
Complete the bell ringer and place in the appropriate place in your notebook.
Home learning 1 was distributed and explained. You have two copies; complete one for you and the other to submit. You can find the home learning below. Be sure to record it in your notebook on page 3.
This is HL 1. Complete a copy to submit and one for your notebook.
Types of Reactions reports were collected.
We watched a video on balancing chemical equations. You can see it below.
Watch the video to learn about balancing chemical equations.
We then took notes on naming chemical compounds. Click the link Writing and Naming Formulas Of Ionic and Covalent Compounds. You do not have to write any information you already know, such as the definitions of ionic and covalent bonds, and valence electrons. You DO, however, need to write down the The 5 Steps for writing an
ionic compound formula and the information on page 35 about naming binary compounds.
There are several handouts that we began last class period (you can find them on the blog for Feb 02/03). You should continue and complete those handouts on balancing equations and naming chemical compounds. Below, you will find a handy reference on how to name compounds. It is to be placed in your notebook.
Use this handy reference when naming compounds.
Students will take QSBA2 next class period, and should look over all notes from second grading period.
SMALL GROUP/INDEPENDENT PRACTICE/DI
Students who compete work early should go to
Khan Academy - chemical reactions and stoichiometry - balancing chemical reactions
HOTS:
-Explain how the Law of Conservation of Mass relates to a balanced equation.
-Does the Big Bang Theory contradict the Law of Conservation of Mass? Explain your reasoning.
EXIT STRATEGY: Quick write - In notebook, write to explain the difference in naming molecular and ionic compounds.
