Objectives-
|
(5) Matter and energy. The student knows that matter is composed
of atoms and has chemical and physical properties. The student is
expected to:
(C) interpret the arrangement of the Periodic Table, including groups
and periods, to explain how properties are used to classify elements; |
| |
|
Materials and Aids-
|
| 12 shape cut-outs, shapes instructions, periodic table, periodic
table notes page, element square notes, "Who am I?" handout |
| |
|
Procedures/Methods-
|
|
A. Introduction-
1. The students will complete a warm-up (four questions over the
periodic table)
2. The students will complete coloring metals, nonmetals and metalloids
on their personal copy of the periodic table. |
| |
|
|
B. Development-
1. Students will be given twelve squares with images of various
sizes, shapes, numbers and backgrounds.
2. They will be asked to arrange the squares in groups with similar
properties
3. These shapes will then be organized into patterns in rows and columns.
4. The students will answer questions on the "Looking for Patterns"
handout. We will go over them upon completion. |

|
|
C. Practice-
1. The students will view a 3.5 minute Bill Nye the Science Guy
video clip about the periodic table.
2. The students will take notes on the "My Chemistry Notes: The Periodic
Table" CLOZE notesheet using the document camera. |
| |
|
|
D. Independent Practice-
1. The teacher will show and explain how to find the number of protons,
electrons and neutrons based on each element's atomic mass and atomic
number.
2. An example will be shown using a large foam-board "Boron" element
square.
3. The class will work one or two more examples together.
4. Students will be left with 8 or 9 more elements to direct, independently. |
| |
|
|
E. Accommodations (Differentiated Instruction)-
|
|
F. Checking for understanding-
After the students have worked at least 9 element squares, they
will complete the "Who Am I? worksheet.
They will need to use their knowledge and the Periodic Table to unmask
the identities of 20 elements using clues. They must list both the
name of the element and the element's symbol. |
| |
|
|
G. Closure-
| After the class has put their things away, ask them questions using
the large Periodic Table in the room. |
