These aliens have many similarities and differences and NASA is in need of a way to organize these life forms.
Your job is to create a table to arrange these new life forms.

5. Getting Started NASA’s instructions:
Organize the aliens in a rectangular block.
Each group (vertical column) must be the same in some way and must have some feature that changes regularly as you move down the group.
Each period (horizontal row) must also share one thing in common and also must have one feature that changes regularly as you go across the periodic table.

pre-LAB
This lab is used to introduce periodicity and trends in the periodic table.
Students work in small groups to organize aliens into a meaningful pattern.
Two aliens are missing and the students task is to draw pictures of the missing aliens.
Students learn to organize information and predict patterns.

9. Aliens "A"
We print the cards on colored card stock and laminate them. This helps students keep track of their cards.
The teacher removes two cards from each deck and has the students group the cards; look for pattern and finally draw the missing aliens.
