Classroom Resources: Molecules & Bonding

1 – 2 of 2 Classroom Resources

• 

  Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School

  Animation: Solubility Animation

  This animation explores how ionic and molecular compounds dissolve (or don’t) in water. Students will see that if an ionic compound such as salt dissolves, the ions dissociate, whereas the molecules in a molecular compound such as sugar remain intact but are separated from one another by water molecules. They will also see that some ionic compounds such as chalk do not dissolve, and the cations and anions remain stuck together. **This video has no audio**

  Molecular Structure, Molecular Geometry, History, Periodic Table, Molecular Structure | Elementary School, Middle School, High School

  Video: Phosphorous Video

  In this video, Sam Kean tells the story of how phosphorus was at the center of the race to discover the structure of DNA.
