Building Atoms and Molecules
Grade 6th Grade · Science · 45 min· Develop Models To Describe The Atomic Composition Of Simple Molecules And Extended Structures. Emphasis Is On Developing Models Of Molecules That Vary In Complexity. Examples Of Simple Molecules Could Include Carbon Dioxide And Water. Examples Of Extended Structures Could Include Sodium Chloride Or Diamonds. Examples Of Molecular-level Models Could Include Drawings, 3-d Models, Or Computer Representations Showing Different Molecules With Different Types Of Atoms. Structure And Properties Of Matter Substances Are Made From Different Types Of Atoms, Which Combine With One Another In Various Ways. Atoms Form Molecules That Range In Size From Two To Thousands Of Atoms. (ms.ps1.a.a) Solids May Be Formed From Molecules, Or They May Be Extended Structures With Repeating Subunits (e.g., Crystals). (ms.ps1a.e)

Guided Notes
3 key concepts
- 1
An atom is the smallest piece of an element that still has all the properties of that element.
- 2
The word 'atom' comes from the Greek word meaning uncuttable, because it was once believed that atoms could not be broken down any further.
- 3
Atoms are incredibly tiny; a typical gold ring contains about one sextillion atoms, which is about the same as the estimated number of stars in the observable universe.
