NGSS: 

HS-PS1-2: Simple Chemical Reactions Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. 

Phenomenon: 

Why do some substances, like salt, dissolve in water and allow electricity to flow (like in sports drinks), while others, like sugar, dissolve but don’t conduct electricity? What does this tell us about how different substances are bonded? 

Guiding Questions: 

Do Lewis dot diagrams represent all of the electrons in an element? If not, what electrons are being represented? How many electrons can any electron shell but the first hold? 

What are some of the key differences between ionic and covalent bonds? 

What do we notice in the products of ionic and covalent bonds? Are there any key differences? 

How can we predict whether an element will share, steal, or give away its valence electrons? 

Learning Objectives: 

• Understand fundamental differences between ionic and covalent bonds 

• Draw lewis dot diagrams, electron transfers, and compounds resulting from ionic and covalent bonds

Phenomenon: 

What are the properties of water that make it unique and important for life? 

Guiding Questions: 

What would happen if you stopped drinking water? 

How important is water to humans? What about the environment as a whole?

What is a hydrogen bond, and how does this relate to polar compounds? 

How can we define the following vocabulary based on the lab staons and how we noced water behaved? Adhesion, Cohesion, Surface Tension, Capillary Action, Density, Miscibility, Solvent, Solute 

Learning Objectives: 

• Understand that water participates in hydrogen bonding, but is unique from various other molecules and compounds found in nature

• Articulate why water is so important to humans and nature
