Alien Periodic Table
Procedure:
**Create a periodic table of elements
that has 8 groups and 5 periods. The
group aliens must be exactly the same in ONE way (the Key Similarity) and must
also share one feature that changes in a periodic pattern as you move down the
group (the Varying Trait). Within each
period, the aliens must be exactly the
same in ONE way (the Key Similarity) and must also share one feature that
changes in a periodic pattern as you move across the period (the Varying
Trait).
**Two aliens are missing from your
set, leave empty spaces to draw them in later.
Questions:
1. How many
groups of aliens do you have? ________
How many periods of aliens do you have? ________
2. Draw in the
missing aliens and describe. Group ______ Period ____
Description of missing alien #1 Drawing of missing alien #1
(Give 5
characteristics of the alien)

Description of missing alien #2 Drawing of missing alien #2
Group ______ Period ____

3. Give detailed information about your
chart of aliens. Then list the Key Similarity and Varying Trait for the aliens
in that group. Be very specific about
what is staying the same and changing.

Period 4 _____________________ __________________
Period 5 _____________________ __________________
4. The ‘Next’
Alien? For one group and one period…
Group number: _____
Period number: _____
A) Describe what the ‘next’ alien
might look like
B) Draw neatly what it might look
like
The ‘next’ alien almost certainly
has… Drawing
of ‘next’ alien

Analyzing and Comparing Questions:
5. What do the groups of aliens have
in common (how are they similar) to the groups/families of atoms on periodic
table? Think about how the groups on the periodic table are similar and compare
to your aliens.
6. How are the periods of the aliens
in common to the periods on the periodic table? What similarities do they have?
7. Compare the alien in group 1,
period 1 to the atom in group 1, period 1 (hydrogen) on the periodic table. How
are they similar; compare their characteristics. Think about what are the
characteristics of the hydrogen atom.
