Introduction to Periodicity Aliens Introduction to Periodicity

Your Mission NASA has recently found life on a nearby planet! 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.

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. g r o u p period

The Aliens that Escaped Two of the aliens found escaped in the transportation process. NASA would like you to make drawings of what you believe those aliens looked like. They would also like you to describe the two missing aliens.

The Aliens We Didn’t Find Describe what the next alien would look like in your periodic table. Also include a drawing of this alien. 1 2 3 4 5 6 7 8 X Period __ & Group __ 1 2 3 4 5 Y Period __ & Group __

Teacher Notes Printable copy of LAB Printable copy of 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.

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. Developed by John Bergmann and Jeff Christopherson

1 2 3 4 5 6 7 8 2 3 4 5 This table has six periods and 9 groups (families). You will most likely have your table with six families (same body type) and 9 periods. Notice that the number of fingers increases as you move from left to right. The hair or number of legs or foot length increases as you move from top to bottom. Answer Key
