Measurement and The Mole
Almost everything is made up of matter and matter is defined as anything that has mass and volume. We will look at the make up of matter and how we can quantify and measure it as well as the interactions of matter that result in the formation of new substances. At the end of the unit you will be able to
Upon Completion of the Unit You will be able to:
- Define matter and identify its physical states
- Distinguish the difference between chemical and physical properties as well as identify chemical and physical changes
- Characterize matter as pure or a mixture and any of its sub classficiations
- Define the mole and perform basic mole conversions
- Define mole ratio and use molar mass as a conversion factor in solving stoichiometry problems
- Demonstrate problems involving conversions from moles of given to moles of unknown
- Explain the concept and perform calculations involving limiting reactant and percent yield
- Calculate the percent composition using mass and molar mass
- determine the empirical formula and molecular formula from percent composition
- SI units
- Accuracy vs. Precision
- Extensive vs. Intensive Properties: be able to define and identify what is an extensive and intensive property
- Scientific Notation
- Significant Figures: be able to assign the correct number of sig figs and determine the number of sig figs during a calculation
- Dimensional Analysis
Day 1: 8/22
\Course Expectations: Today you will become familiar with course expectations and the syllabus. Please bring to class everyday your packet, something to write with, and something to take notes on. We will finish the day with what floats your boat (this does not need to be made up).
Day 2: 8/25
Lab Safety: Today will be all about lab safety. Remember if it does not seem like a good idea DO NOT do it. By the end of class you will be able to locate all of the safety features of the classroom, know what to do in case of emergency. During class you will identify and explore the uses of specific pieces of lab equipment. This will be completed using google classroom (Lab Equipment Exploration).
Watch the following for Monday and answer the questions on goformative.com about Dimensional Analysis.
Day 3: 8/29
Scientific Notation, SI units, and Dimensional Analysis: Today in class we how to properly use scientific notation, SI units and work dimensional analysis problems (you should have watched the video). You will also create a rainbow using dimensional Analysis.

Watch the following for Wednesday and answer the questions on goformative.com about Significant Figures and Error in the Laboratory
Other Links that may interest you.
Day 4: 8/31
Significant Figures and Error in the Laboratory: Today you determine how many significant figures (SFs) a number has and determine how many SFs to record during Accuracy v Precision of Glassware.
Accuracy v Precision of Glassware Investigation
Day 7: 9/9
Today during lab you will explore the properties of matter and how this allows us to know a reaction has taken place. From this you will begin to be able to identify the types of reactions based off of the reactants (starting substance(s)) and products (ending substance(s)).
Classification of Changes in Matter
Classification of Changes in Matter Report Template
For Monday have a rough draft of your lab report completed and printed for peer review.
Day 5: 9/2
Numbers in Science Lab: Today in class you will explore how the instrument used to measure can make a difference in the measurement.
Numbers in Science Lab
Watch the following video over properties of matter for Friday and answer the questions in google classroom about properties of matter.
Day 8: 9/12
Quiz 1.1 over lessons 1.2-1.7
Today in class after completing the quiz, you will peer review your lab report.
Day 6: 9/7
Exploration of matter and its properties: Today during lab you will explore the properties of matter and how this allows us to know a reaction has taken place. From this you will begin to be able to identify the types of reactions based off of the reactants (starting substance(s)) and products (ending substance(s)). We will finish the lab during the next class.

Day 9: 9/14
How did they know a reaction was taking place? Now that you know how changes in matter and the formation of new matter results indicates a chemical reaction has taken place, you will be able to write, balance, and classify the reaction as one of five main different types. You will also complete the types of chemical reactions lab.
Types of Chemical Reactions
Day 10: 9/19
How did the calculate the amount of product produced?
For next class please watch the video on mole and mole conversions. Once you have watched the video complete the goformative.
Day 11: 9/21
What is a mole? Today you will determine Avogadro's number and its relationship to the mole. You will also look at how the mole is central to chemistry.
Determining Avogadro's Number
How big is a mole?
What if there was a mole of moles?
For the next class watch the video on stoichiometry. Once you have watched the video complete the goformative.
