4. Confidential:
Late last night, a low-flying alien spacecraft was spotted flying in the sky by people driving down the intersection of 183 and Burnet Road.
At 11: 42 PM a large explosion followed by an enormous flash of light was reported near the Taco Cabana, just west of Burnet Middle School.
A family of aliens was taken into custody, but there is reason to believe an additional alien is on the loose. Examine and sort the cards provided and make a drawing of the missing alien to give the authorities. 4

5. Missing Alien

Record all patterns in your composition book.
Predict what the missing alien would look like.
Draw your missing alien on the card provided by your teacher. 5

20. Periodic Table of Elements
Ask students where the metals are, where the non metals are and where the metalloids are.
Listen for ZigZag or stairstep line as the divider for metalloids.
Metals are on the left
Nonmetals are on the right
Metalloids are by the stairstep – there are 8 metalloids

21. Periodic Table of Elements
Identify where we would find
Metals- color them red
Non-metals – color them blue
And Metalloids. – color them purple (there are only 8)
Tell students to color lightly and put a key or legend on their table so they can identify them later.
Color the metalloids first- then use it as a dividing line between the others.

22. Color the Metalloids first – there are only 8
Students will color in their periodic table – remind them not to color in too darkly they need to be able to read it!
Color metalloids first – it makes it easier.
H is a non-metal weirdo on the left side.
Color the Metalloids first – there are only 8
B, Si, Ge, As, Sb, Te, Po, and At
Don’t forget- H is a non-metal weirdo on the left side

23. METALS Found on left side of periodic table Shiny- looks like metal!
Malleable ( can bend)
Ductile ( can be made into wire)
Good conductor of heat and electricity
Examples from your life?
This will be the notes on the first column of your tri fold

24. Metalloids Near the zigzag line on the periodic table
“KIND OF” elements
Some are “kind of” shiny, “kind of” dull
Some are “kind of” good at conducting heat and electricity
Some are “kind of” malleable – can bend a little bit
Examples from your life?
Second column of your tri fold

25. Non-metals Found on the right side of the periodic table
Dull ( not shiny)
Most are gases
Brittle ( break easily- cannot bend)
Poor conductors of heat and electricity
Examples from your life?
Third column of your tri fold.

26. What is another name for Group?
TAKE A GUESS
Where are the groups ?
Where are the periods?
What is another name for Group?
The groups are at the top of the periodic table.
There are 18 groups.
Another name for a group is a Family.
The Periods are at the side of the chart.
Hint; Sentences have a period at the end. You read a sentence across the page.

27. Groups or Families
Groups are columns ( go down) on the periodic table. All elements in the same group or family have similar characteristics – they act alike ( just like your family).
Have students write GROUPS at the top of their columns
LABEL GROUPS AT THE TOP OF YOUR CHART
Another word for Groups is FAMILY – write it too!

28. Periods
Periods are rows across the periodic table. The elements gain protons and electrons as we move across the period.
Have students label PERIODS at the side of the chart
Label PERIODS on the side of your periodic table.

29. Name those elements Group 14, Period 2 Group 11, period 4
Group 14, Period 2 – Carbon
Group 11, Period 4 – Copper
Group 2, Period 2 – Beryllium
Group 17, Period 3 – Chlorine
Group 1, Period 18 - Helium

30. Vocabulary Cards
