Data Collection- Group Collaboration
Use the PhET simulator to explore the bonds and geometries of different molecules, and investigate how those impact molecular properties.

HAVE 1 PERSON AT YOUR TABLE OPEN THIS TO CREATE A COPY.


**SHARE THE COPY WITH EVERYONE AT YOUR TABLE**


Split the work for the molecules on the document and work together to complete the table.

Use pubchem to research molecular properties.

Conclusion- Individual Responses

Answer 5, 6, & 7 using the data you collected with your group.


These answers can be discussed with your group, but written responses must be your own.

1.5

What patterns did you notice about symmetry?

Hint: If molecules are symmetrical, what do they have in common? If they are not symmetrical, what did you notice?

1.5

What patterns did you notice about bond types (polar or nonpolar)?

Possible sentence starters:
"I see that polar bonds seem to happen when....but non polar bonds..."
"Polar bonds show up with bond diploe arrows that...but..."

3

What overall patterns did you notice about bonding & geometry (shape) and the molecular properties you found?

YOUR RESPONSE SHOULD INCLUDE:
  1. STATE OF MATTER
  2. SOLUBILITY
  3. MELTING POINT

"Molecules that are gas at room temperature are..."
"When molecules are soluble, they are usually..."
"A high/low melting point is consistent with..."
