Notes:

Stage 1: Identify Desired Results

State:	KS       2A:1.1-1.4
Title:	Kansas State Science Standards
Standard(s):	2A:1.1 Atoms are the fundamental organizational unit of matter. 2A:1.2 Atoms have smaller components that have measurable mass and charge. 2A:1.3 The nucleus of an atom is composed of protons and neutrons, which determine the mass of the atom. 2A:1.4 The dense nucleus of an atom is in the center of an electron cloud, and the electron cloud determines the size of the atom.

Understandings:
user	Behavior and characteristics of matter can be predicted by its atomic structure.

Essential Questions:
User	1.How can the components of an atom be used to describe matter? 2.How does the electron arrangement of an atom affect the behavior of matter?

Knowledge and Skills:

K
Atoms are made of protons, neutrons, and electrons.
The specific charges, masses and locations of protons, neutrons and electrons.
The mass of an atom is determined by the protons and neutrons in the atom.
The size of an atom is determined by the number and arrangement of electrons.
Electrons are organized in energy levels.
Atoms tend to form full energy levels to become stable.

S
Determine the number of protons, neutrons and electrons in a given atom.
Describe the charges, masses and locations of protons, neutrons and electrons.
Determine the mass of a given atom. Compare relative sizes of atoms.
Describe the organization of electrons in a given atom.
Explain how atoms form stable arrangements of electrons.

Notes:

Student Directions:
You are an FBI agent assigned to find an element that has escaped from the Periodic Table. Create a Wanted Poster, detailing the description of the element, its common aliases, identifying characteristics and where it is known to frequent. Include a sketch of its appearance on an atomic level. You will also compose and deliver a special press conference bulletin, explaining all of the parts of your poster. Your poster and special press conference bulletin should meet the following criteria: accurate, clear, organized, and thorough with a polished oral delivery justifying all descriptive characteristics.

Other assessment evidence to be collected:

Stage 3: Plan Learning Experiences and Instruction

Learning Activities:

W
Provide handouts laying out the performance requirements, deadlines, rubrics, and reference materials.
Post essential questions.

H
Demonstration showing startling reactions of different elements.

E
Teacher lecture and modeling on atomic structure. Students research information on assigned element.
Using cooperative learning, students determine atomic structure of various elements.

R
In cooperative groups, students will critique and offer feedback on poster design.

E
Students will present their Want Poster / Press conference presentation against criteria of the scoring device.
Students will watch videotape of their oral delivery and self-assess their work.
