Do YOU Remember….?
1. What is an element?
2. What are examples of physical properties used to describe an element?
3. What are examples of chemical properties used to describe an element?
4. How are physical properties used to position elements on the periodic table?
5. Label the atomic structure below and include the mass number and electrical charge.
Pretest…to see what they know
Missing Alien Activity
(Cousin Al)
Students are given pictures of various
aliens that have similar patterns, increasing
body size, increasing number of hair, arms &
fingers. They analyze the aliens and arrange
them in order, using the periodic table as a
guide. When they have completed the task,
they use the periodic table to discover what
alien (element) is missing…which is Aluminum
(Al).
Atomic Structure Relays…
 Student groups are given a dry erase board, dry erase
marker and a periodic table.
 Teacher will give a clue as to what element they must look
up and draw the Bohr Model Atomic structure for that
element

presentation and/or label on model
Power Point Criteria – 6 slides
Title Page to include Element Name, all members
names, teacher name and period
Summary – a brief description of your group’s process
in discovering, evaluating and naming this element…a
great time to tell your story.
 Atomic Structure Information (use Atomic Structure
Relays as a guide)
Physical Characteristic/Properties of Element
(you can use www.chemicalelements.com as a guide)

(you can use www.chemicalelements.com as a guide)
Placement Justification – ELABORATE…give a
justification as to why your element should be placed at
its position on the Periodic Table of the Elements
Please note that when your group presents in front of the
committee, you will have a 7 minute time limit!
