The following Points have been
outlined by SaskLearning to be included in the Chemistry20 Atoms and
Elements Unit. Included is a list of where these points were
addressed. |
|
|
a |
Curriculum Objectives |
| |
Outline Aristotle's
ideas on the nature of matter. |
| |
|
1
Day
5-9: One of the groups prepares a presentation on Aristotle and his
ideas of the "nature of matter."
Day 10: The students are receive a student presentation on
Aristotle.
Day 12&13: The students review Aristotle and his beliefs which is
then followed by a quiz. |
| |
|
|
|
|
| |
Explain the
contributions of the early alchemists. |
| |
|
1
Day
5-9: One of the groups prepares a presentation on Alchemists and
their contribution.
Day 10: The students are receive a student presentation on
Alchemists.
Day 12&13: The students review Alchemists and their contributions
which is then followed by a quiz. |
| |
|
|
|
|
| |
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.
|
| |
|
1
Day
5-9: One of the groups prepares a presentation on one of these
scientists and the hand they played in developing the model of the
atom's structure.
Day 10&11: The students receive a student presentation on the
contributor.
Day 12&13: The students review the atomic model contributions
which is then followed by a quiz. |
| |
|
|
|
|
| |
Understand how theory
is used to explain observations. |
| |
|
1
Day 12:
The root of Aristotle's logic is discussed and how observation
drives theory. This is then applied to the other observations made
by scientists in chronological order and how their findings altered
the model in time. |
| |
|
|
|
|
| |
Identify protons,
neutrons, and electrons as constituents of atoms.
Consider the forces which hold the atom together. |
| |
|
1
Day
5-18: Students work with and discuss the inner workings of the atom
on a daily basis. |
| |
|
|
|
|
| |
Draw Lewis diagrams
to indicate the valence electron structure of atoms. |
| |
|
1
Day 18 |
| |
|
|
|
|
| |
Recognize the
terminology used to describe atoms and their isotopes: atomic
number; nucleon (mass) number; atomic mass; atomic mass unit:
average atomic mass. |
| |
|
1
Day 8,
9, &10 |
| |
|
|
|
|
| |
Discuss the concept of
the mole. |
| |
|
1
Mole
concept is discussed in the introduction unit, then again in the
stoichiometry unit. |
| |
|
|
|
|
| |
Distinguish between
isotopes of an element. |
| |
|
1
Day 8,
9, & 10 |
| |
|
|
|
|

Recognize that there is
a difference between mass and weight. |
| |
|
1
Day 9 |
| |
|
|
|
|
| |
Calculate atomic mass
(atomic weight) values when given the percentage of each isotope of
an element. |
| |
|
1
Day 9
&10 |
| |
|
|
|
|
| |
Recognize that elements
have characteristic properties |
| |
|
1
Day
1-5, 7, 16, 17 &18 |
| |
|
|
|
|
| |
Classify elements
according to their properties.
Identify
some elements by their properties. |
| |
|
1
Day
1-5, 7 &18 |
| |
|
|
|
|
| |
Describe the development
of the periodic table by Mendeleev.
Explain the basic principles of organization of the periodic table.
Identify trends and patterns within the periodic table. |
| |
|
1
Day 4,
5, 15, &18 |
| |
|
|
|
|
| |
Understand the history
of the use of symbols for the elements. |
| |
|
1
Day 1-5 |
| |
|
|
|
|
| |
Use symbols for the
elements correctly |
| |
|
1
Day
1-5, 8-20 |
| |
|
|
|
|
| |
Use the periodic table
to determine the valences of elements. |
| |
|
1
Day 18,
19, &20 |
| |
|
|
|
|
| |
Compare several forms of
the periodic table and recognize that each has its advantages. |
| |
|
1
Objective not met- Universally only one periodic table is used |
| |
|
|
|
|
| |
Incorporate the
vocabulary of chemistry into writing and talk about chemistry.
Recognize
the periodic table as a source of information. |
| |
|
1
Objectives met on a daily basis |
| |
|
|
|
|
| |
Read and interpret
information about elements from charts and tables.
Use
numerical data to compare and describe elements. |
| |
|
1
Day 18 |
| |
|
|
|
|
The curriculum suggests
that this unit runs eight days, but I have extended that to twenty days.
This has been achieved by incorporating two days of laboratory time, and
the ten days of the independent research time.
