Introduction to Chemistry Chapter 1 L. Bernard, 2016

What is chemistry? L. Bernard, 2016

Chemistry is… The study of matter and the changes matter undergoes Affects every aspect of life L. Bernard, 2016

Earth and Space Science Natural Science Physical Science Earth and Space Science Life Science Physics Chemistry Geology Astronomy Botany Zoology Meteorology Oceanography Ecology Genetics L. Bernard, 2016

What is matter? Anything that has mass and occupies space! L. Bernard, 2016

Are chemicals matter? A chemical is any substance that takes part in a chemical reaction or is the product of a chemical reaction Since they all have mass and volume, all chemicals are matter! L. Bernard, 2016

Remember! Matter cannot be created nor destroyed! The Law of Conservation of Mass We can’t create something out of nothing L. Bernard, 2016

Five Areas of Study Organic Chemistry Inorganic Chemistry The study of chemistry containing carbon Inorganic Chemistry The study of chemistry that does NOT contain carbon L. Bernard, 2016

Five Areas of Study Biochemistry Analytical Chemistry The study of chemistry within living organisms Analytical Chemistry The study of the composition of matter Physical Chemistry The study of the energy in chemical reactions L. Bernard, 2016

L. Bernard, 2016

Pure vs Applied Pure chemists research the fundamentals of chemistry Pursuit knowledge of chemistry just because L. Bernard, 2016

Pure vs Applied Applied chemists research chemistry to answer a specific question Pursuit knowledge of chemistry to solve a problem L. Bernard, 2016

Why even study chemistry? L. Bernard, 2016

What types of careers are there that involve chemistry? L. Bernard, 2016

Jobs that need Chemistry! Cosmetologist Doctor/Nurse/Physician Environmentalist Forensic Scientist Astronaut Farmer/Agriculturalist Hair Colorist Food Scientist Lifeguard Paint Mixer Pharmacist Toxicologist Professor L. Bernard, 2016

DO NOW! Place the following steps of the scientific method into the graphic organizer below. Design Experiment Scientific Theory Hypothesis Not Supported Hypothesis Supported Observations Results New Experiment Hypothesis Collect Data Create New Hypothesis L. Bernard, 2016

The Scientific Method L. Bernard, 2016

The Scientific Method is… A systematic approach to solving scientific problems In other words, a list of steps that help us when we are experimenting in the lab L. Bernard, 2016

The Scientific Method Use your observation to make a hypothesis L. Bernard, 2016

The Scientific Method Design an experiment to test that specific hypothesis Independent Variable-the variable that is changed; manipulated variable Dependent Variable- the variable that is observed; responding variable L. Bernard, 2016

The Scientific Method After experimenting, evaluate your results Was your hypothesis supported? Do you need to perform more trials? How can you revise your hypothesis? What improvements could be made? L. Bernard, 2016

The Penny Drop How many drops of water will fit on the top of a penny? Use the scientific method graphic organizer to create your own experiment regarding this question: How many drops of water will fit on the top of a penny? What other criteria could affect how many drops of water fit on the penny? L. Bernard, 2016

Do Now! Try to identify the pieces of lab equipment in front of you. What are their functions and purposes? L. Bernard, 2016

Setting Up Your Lab Notebook Table of Contents on first page Number each page! Experiment #, Lab Title, Page # L. Bernard, 2016

Setting Up Your Lab Notebook Title and Date List your lab partners Describe the lab List materials Give brief summary of procedures Pre-Lab questions and hypothesis Data table and diagrams Obsesrvations Post-lab questions Conclusion What did you learn? Why did we do this lab? How could this lab be improved? Reflect on the experience! L. Bernard, 2016

Problem Solving in Chemistry Chapter 1.4 L. Bernard, 2016

Effective Problem Solving Develop a plan Implement that plan L. Bernard, 2016

Solving Numeric Problems Analyze What do you know? What do you not know? What can you do to find what you do not know? Calculate Conversions or equations L. Bernard, 2016

Solving Numeric Problems Evaluate Does your answer make sense? Did you use the correct equations? Was the data copied correctly? Where there any errors that you made? Are your units correct? L. Bernard, 2016

Solving Non-numeric Problems Analyze, then solve! No numbers mean no calculations You still need to determine what you know and don’t know, then develop a plan Apply concepts to the problem L. Bernard, 2016

Presenting your Data Numerical Data Non-Numerical Data Tables Graphs T-Charts Venn-diagrams L. Bernard, 2016

How do I draw a proper graph? L. Bernard, 2016
