2. Essential Questions Why is it important to study chemistry?
How do chemists solve problems?
- Have students discuss within small groups what they believe the answer to these questions are. Post answers on chart paper.

3. Key Questions 1.1 Why is the scope of chemistry so vast?
What are five traditional areas of study in chemistry?
What are the central themes of chemistry?
- refer to the Vade Mecum and explain the expectation of the vocabulary, book notes and exercises. Remind them these are due prior to instruction.
1.5 days for Chapter 1 completion (scientific method and problem solving will be practiced and reviewed throughout the semester)
Have students refer to example of book notes in the Vade Mecum. Use this first chapter to instruct how to complete vocabulary, book notes and book exercises. (I do, We do, Students do format)

4. What is chemistry?
To understand chemistry you need to understand what matter is.
Matter is anything that has mass and takes up space.
Can you think of anything that is made up of matter?

5. What is chemistry?
Chemistry studies the composition of matter and the changes that matter undergoes.

6. Key Question: Why is the scope of chemistry so vast?
Chemistry affects all aspects of life and most natural events because all living and nonliving things are made of matter.

7. Key question What are five traditional areas of study in chemistry?
Because the scope of chemistry is so vast it is broken into different areas of study.
Organic Chemistry
Inorganic Chemistry
Biochemistry
Analytical Chemistry
Physical Chemistry

8. Key Question What are the central themes of chemistry?
To truly understand chemistry you need to study all of the Big Ideas.
Chemistry as the Central Science
Electrons and the structure of atoms
Bonding and interactions
Reactions
Kinetic theory
The mole and quantifying matter
Matter and energy
Carbon chemistry
List the big ideas, then with individual clicks the areas to be introduced during the semester will pulse
- Have students look at the book exercises in the Vade Mecum

9. Key Questions 1.2 What are three general reasons to study chemistry?
What are some outcomes of modern research in chemistry?
1.5 days for Chapter 1 completion (scientific method and problem solving will be practiced and reviewed throughout the semester)
Have students refer to example of book notes in the Vade Mecum. Use this first chapter to instruct how to complete vocabulary, book notes and book exercises. (I do, We do, Students do format)

10. Why study chemistry? Explaining the natural world:
Why do apples turn brown?
Why does sugar dissolve faster in hot water than cold water?
How do antibiotics work?

11. Why study chemistry? Preparing for a career
You do not need to be a chemist to benefit from knowledge in chemistry.
Firefighters
Landscapers
Food service

12. Why study chemistry? Being an informed citizen
Many decisions you need to make in life involve chemistry
Voting on initiatives
Medical
Understanding environmental issues

13. Key Questions what are some outcomes of modern research in chemistry?
Modern research in chemistry can lead to technologies that aim to benefit the environment, conserve and produce energy, improve human life and expand our knowledge of the universe.

14. Pogil Time!!! – Fundamentals of Experimental Design and organizing data
What is a POGIL?
Process Oriented Guided Inquiry Learning
Groups of two or three
Listen, read and follow all instructions carefully!!
Raise your hand when you reach teacher check points.
Be prepared for discussion

15. Key Questions 1.3 How did Lavoisier help to transform chemistry?
What procedures are at the core of scientific methodology?
What role do collaboration and communication play in science?

16. Alchemy to science
Alchemist tried to change metals, such as changing lead to gold.
Alchemy did not provide a logical set of explanations for the changes in matter that they observed.
The shift to science began in the 1500’s
Science based its conclusions about the natural world on experimental evidence, not on philosophical debates.

17. Key Questions How did Lavoisier help to transform chemistry?
Lavoisier helped to transform chemistry from a science of observation to the science of measurement that it is today.

18. Scientific Methodology
A very logical, systematic approach to the solution of a scientific problem.
Making observations
Qualitative – color, bubbles, texture, etc
Quantitative – measurements, counting, etc
Hypothesis – proposed explanation in response to the problem/question
If, then, because format
Experiment – procedure used to test hypothesis
Variables
Independent – you change
Dependent – what you measure or observe due to the change in the IV
Control – important variables that must stay constant

19. Model – are often used to represent something better.
A model of the solar system allows students to understand the organization of the planets better.
When a proposed explanation, hypothesis, has been tested many times by different scientist it may become a theory.
A law generalizes a body of observations. At the time it is made, no exceptions have been found to a law. Scientific laws explain things, but they do not describe them. One way to tell a law and a theory apart is to ask if the description gives you a means to explain 'why'.

20. Key Question What procedures are at the core of scientific methodology?
Scientific methodology involves making observations, proposing an dtesting hypothesis, and developing theories.

21. Collaboration and communication?
Why collaborate?
Share knowledge
Different disciplines
Research/industry
Communication
Necessary to collaborate
Verbal, written, technology, etc

22. Key question what role do collaboration and communication play in science?
When scientists collaborate and communicate with one another, they increase the likelihood of a successful outcome.

23. Key questions 1.4 What is a general approach to solving a problem?
What are the steps for solving numeric problems?
What are the steps for solving non-numeric problems?

24. Key question what is a general approach to solving a problem?
Effective problem solving always involves developing a plan and then implementing that plan.

25. Solving numeric problems
1. Analyze:
Read the problem to determine what is known and exactly what unkown(s) you need to determine.
Make a plan for using what is know to determine the unknown.
Draw a diagram, table, chart, or picture to help you draw a relationship between the known and unknown.
Determine if you need a equation

26. 2. Calculate:
Rearrange the equation to solve for the unknown when necessary.
Use a calculator to avoid mistakes.
Convert units when necessary.
3. Evaluate:
Is your answer reasonable?
Reread the problem and be sure your found the answer that makes sense.
Do you have the correct units, labels, and significant figures?

27. Key question: what are the steps for solving numeric problems?
The steps for solving a numeric work problem are analyze, calculate, and evaluate.

28. Estimate Walking Time You are visiting Indianapolis for the first time
Estimate Walking Time You are visiting Indianapolis for the first time. It is a nice day, so you decide to walk form the Indiana State Capital to the Murat Centre for an afternoon performance. According to the map the shortest route from the capital to the theater is eight blocks. How many minutes will the trip take if you can walk one mile in 20 minutes? Assume that ten blocks equals one mile.

29. Solving nonnumeric problems
1. Analyze:
Read the problem to determine what is known and exactly what unkown(s) you need to determine.
Make a plan for using what is know to determine the unknown.
Draw a picture, table or diagram to help you understand
2. Solve
Make a relationship between the known and the unknown you need to determine.
Re-read the problem to make sure your answer makes sense and answers the unknown.

30. Key question: what are the steps for solving nonnumeric problems?
The steps for solving a nonnumeric problem are analyze and solve.
