TRANSCRIPT

  • Slide 1
  • Chapter 1 Introduction to Chemistry Milbank High School
  • Slide 2
  • Section 1.1 Chemistry OBJECTIVES: Define chemistry and differentiate among its traditional divisions.
  • Slide 3
  • Section 1.1 Chemistry OBJECTIVES: List several reasons to study chemistry.
  • Slide 4
  • What is Chemistry? The study of matter, its composition, properties, and the changes it undergoes. Everyday life? Applied Chemistry- is using chemistry to attain certain goals, in fields like medicine, agriculture, and manufacturing Pure chemistry- gathers knowledge for the sake of knowledge
  • Slide 5
  • 5 Major Areas of Chemistry Analytical Chemistry- concerned with the composition of substances. Inorganic Chemistry- primarily deals with substances without carbon Organic Chemistry- essentially all substances containing carbon Biochemistry- Chemistry of living things Physical Chemistry- describes the behavior of chemicals (ex. stretching)
  • Slide 6
  • Chemistry is central to modern science, and to almost all human endeavors. important to all sciences - biology, geology, physics, engineers, etc. a natural science. a language with its own vocabulary. a way of thinking.
  • Slide 7
  • Why Study Chemistry? everyone and everything around us involves chemistry What in the world isnt Chemistry? helps you make choices possible career for your future used to attain a specific goal Do you remember pure and applied chemistry?
  • Slide 8
  • Section 1.2 Chemistry Far and Wide OBJECTIVES: Summarize ways in which chemistry affects your daily life.
  • Slide 9
  • Section 1.2 Chemistry Far and Wide OBJECTIVES: Describe the impact of chemistry on various fields of science.
  • Slide 10
  • Chemistry Far and Wide Materials- perfume, steel, ceramics, plastics, rubber, paints, nonstick cooking utensils, polyester fibers Energy- greater demands conserve it, or produce more fossil fuels, solar, batteries, nuclear (dont forget pollution!)
  • Slide 11
  • Chemistry Far and Wide Medicine and Biotechnology- vitamin C, penicillin, aspirin materials for artery transplants and hipbones Human Genome Project bacteria producing insulin cloning
  • Slide 12
  • Chemistry Far and Wide Agriculture- worlds food supply plant growth hormones ways to protect crops disease resistant plants The Environment- both risks and benefits involved in discoveries carbon dioxide, ozone, warming
  • Slide 13
  • Chemistry Far and Wide Astronomy and Space Exploration- composition of the planets analyze moon rocks planet atmospheres life on other planets?
  • Slide 14
  • Section 1.3 Thinking Like a Scientist OBJECTIVES: Describe the steps involved in the scientific method.
  • Slide 15
  • Section 1.3 Thinking Like a Scientist OBJECTIVES: Distinguish between a theory and a scientific law.
  • Slide 16
  • The Scientific Method A logical approach to solving problems or answering questions. Starts with observation- noting and recording facts hypothesis- an educated guess as to the cause of the problem, or a proposed explanation
  • Slide 17
  • Scientific Method controlled experiment- designed to test the hypothesis only two possible answers hypothesis is right hypothesis is wrong Generates data observations from experiments. Modify hypothesis - repeat the cycle
  • Slide 18
  • Observations Hypothesis Experiment Cycle repeats many times. The hypothesis gets more and more certain. Becomes a theory A thoroughly tested model that explains why things behave a certain way.
  • Slide 19
  • Theory can never be proven- due to new information Useful because they predict behavior Help us form mental pictures of processes (models) Observations Hypothesis Experiment
  • Slide 20
  • Another outcome is that certain behavior is repeated many times Scientific Law is developed (math?) Describes how things behave Law- tells how Theory- tells why Observations Hypothesis Experiment
  • Slide 21
  • Law Theory (Model) Prediction Experiment Modify Observations Hypothesis Experiment
  • Slide 22
  • Section 1.4 How to Study Chemistry OBJECTIVES: Explain why learning chemistry requires daily effort.
  • Slide 23
  • Section 1.4 How to Study Chemistry OBJECTIVES: Describe the importance of writing in the study of chemistry.
  • Slide 24
  • How to Study Chemistry Understanding and Applying Concepts requires effort on your part read materials carefully take thorough notes you can use study often and effectively quiet, well-lit, remove distractions
  • Slide 25
  • How to Study Chemistry Understanding and Applying Concepts chemistry has a language of its own, so learn the vocabulary look around you, and make the connection to the level of atoms and molecules
  • Slide 26
  • How to Study Chemistry Using Your Textbook name chemical compounds write chemical formulas interpret graphs techniques to solve problems Use your Teacher and Textbook!
  • Slide 27
  • How to Study Chemistry Using Your Textbook take good notes solve Practice Problems read, keeping objectives in mind Student Study Guide (p. 24) section summaries; Key Terms
  • Slide 28
  • How to Study Chemistry On Your Own go beyond the textbook make flashcards reread and rewrite notes quiz yourself and classmates form a study group ASK, ASK, and ASK
  • Slide 29
  • How to Study Chemistry Tests and Quizzes cramming never a good idea set aside a certain amount of time every day get enough rest daily; nutrition read tests carefully / thoroughly do easy problems first show work, and evaluate answer
