Introduction
In 1869, a Scientist named Dimitry Mendeleyev constructed the first periodic table.
He organized the elements according to their families, atomic numbers and many other
properties. Today, the periodic table shows 112 elements.
Elements are pure substances made of only one kind of atom. Atoms are tiny
structures found in all matter. Most substances contain many different atoms. Only
elements contain only one kind of atom.
•
•
•
ELEMENTS:One kind of atom and pure
COMPOUNDS:Two or more kinds of atoms chemically bonded.
MIXTURES: Two or more elements or compounds physically together and it is not
pure.
We will study the periodic table and make one wall-size periodic table showing at least one
use for each element.

Task: The assignment
1. We will be studying 84 elements on the periodic table.
There will be seven groups you are assigned to; four to
a group.
2. Each individual is responsible for making three 5x7
note cards on the elements provided you have 50
mintues.
3. Your periodic table should contain element name,
symbol, atomic number, and whole host of scientific
data.
4. You will need a black marker and may use any color to
represent your elements. Include one place you can
find your element in.
5. Review the Periodic Element lecture online, take
notes. Then present to class.
6. Afterwards take the group quiz online.
7. Evaluate your group work.

Get into your the cooperative groups and assign group leaders.
Leader: Student passes out the cards and checks that directions are being
understood.
Materials manager: student brings all materials to your group.
Communicator: This student will collect completed note cards and return them to
the teacher as well as ask any questions.
Computer Expert: This student will lead the group in completing the online lesson
and quiz.
Search for elements in text books or online for the necessary information and write
it done on the 5x7 note cards.
Present individual cards to class .

Objectives:
– Students should have an idea about the 84 elements
– Understand physical, chemical, and atomic properties of matter.
– Students should be able to identify the element locations, trends, and physical properties.
Materials: will need 5x7 note cards, markers, crayons, colored pencils, tape, text books, and computer.
Notes: There are no atomic numbers on original periodic table, only atomic weights and the groupings of
elements based on their known properties. 30 years later J. J. Thomson suggested that the electronic
configuration of atoms might account for the periodicity of the elements, 40 years would pass before atomic
numbers were recognized as the basis for ordering the elements.
Science standard 5:
PO 1. Describe substances based on their physical properties. PO 2. Describe substances based on their
chemical properties. PO 3. Predict properties of elements and compounds using trends of the periodic table
(e.g., metals, non-metals, bonding – ionic/covalent). PO 4. Separate mixtures of substances based on their
physical properties. PO 5. Describe the properties of electric charge and the conservation of electric charge.
PO 6. Describe the following features and components of the atom:
•
•

•
•
•
•
protons
neutrons
electrons
mass
number and type of particles
structure
organization
