THINKING ROUTINE

VERY close looking

 

Look carefully, slowly and deliberately at THREE different materials around you.  For EACH ONE answer the following with detail and considered thought

:

What do you see?

What do you think about that?

What does it make you wonder?

HS-PS1-3 Bonding and imfs

Matter and its Interactions
Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

Intermolecular forces and melting point, boiling point, vapor pressure and surface tension.
