INTRODUCTION TO CHEMISTRY, ATOMS AND ELEMENTS
-------------------------------------------------------------------------PART 1
A) Identify and explain how chemistry affects us.
1. Discuss how advances in chemistry have led to the development of new products.
2. Outline the societal impact of new chemical products.
3. Recognize that advances in chemistry are often driven by societal needs.
4. Explain the relationship between science and technology.
5. Identify some issues or problems for which a knowledge of chemistry is important in
identifying causes and solutions.
6. Recognize that some problems can not be solved by science.
B) Use a wide range of language experiences for developing knowledge of the
importance of chemistry.
1. Show understanding by providing an alternative rephrasing, drawing a diagram or making a
model.
2. Synthesize ideas gleaned from a variety of sources and media.
3. Identify critical issues in factual and editorial argumentative messages from both print and nonprint media.
4. Create questions as tools to further understanding of concepts.
C) Develop an understanding of how knowledge is obtained, evaluated, refined and
changed within chemistry.
1. Focus attention on personal knowledge, and gaps in that knowledge.
2. Reflect upon how knowledge is created, refined and applied in chemistry.
D) Come to a better understanding of the personal, moral, social, and cultural
aspects of chemistry.
1. Understand how application of chemical principles through technology influences the natural
environment.
2. Establish arguments based on human rights, human needs or the needs of the environment with
respect to the use of knowledge about chemical principles.
3. Explore how moral principles influence judgements about the application of chemical
principles.
E) Develop a positive disposition to life-long learning.
1. Cooperate with each other in order to enhance understanding through shared information.
2. Move from choosing among teacher-directed activities toward creating self-directed activities
pertinent to chemistry.
3. Develop a willingness to take risks as independent learners.
4. Recognize the inevitability of profound change due to technological innovations and changes
in society's values and norms.
5. Be willing to try to influence change by continuing to learn and apply what is learned.
PART 2
F) Discuss the development of ideas about the structure of matter.
1. Outline Aristotle's ideas on the nature of matter.
2. Explain the contributions of the early alchemists.
3. Summarize the contributions made by Dalton, Lavoisier, Berzelius, Thomson, Rutherford,
Milliken, Planck, Bohr, de Broglie, Schrödinger or Heisenberg in developing a model of the
structure of the atom.
4. Understand how theory is used to explain observations.
G) Identify the relationships among the components of the atom.
1. Identify protons, neutrons, and electrons as constituents of atoms.
2. Consider the forces which hold the atom together.
3. Draw Lewis diagrams to indicate the valence electron structure of atoms.
4. Recognize the terminology used to describe atoms and their isotopes: atomic number; nucleon
(mass) number; atomic mass; atomic mass unit: average atomic mass.
5. Discuss the concept of the mole.
6. Distinguish between isotopes of an element.
7. Recognize that there is a difference between mass and weight.
8. Calculate atomic mass (atomic weight) values when given the percentage of each isotope of an
element.
H) Examine how elements are described and classified.
1. Recognize that elements have characteristic properties.
2. Classify elements according to their properties.
3. Identify some elements by their properties.
4. Describe the development of the periodic table by Mendeleev.
5. Explain the basic principles of organization of the periodic table.
6. Identify trends and patterns within the periodic table.
7. Understand the history of the use of symbols for the elements.
8. Use symbols for the elements correctly.
9. Use the periodic table to determine the valences of elements.
10. Compare several forms of the periodic table and recognize that each has its advantages.
I) Understand and use the vocabulary, structures and forms of expression which
characterize chemistry.
1. Incorporate the vocabulary of chemistry into writing and talk about chemistry.
2. Recognize the periodic table as a source of information.
J) Apply knowledge of numbers and their interrelationships.
1. Read and interpret information about elements from charts and tables.
2. Use numerical data to compare and describe elements.
