Classroom Resources: Molecules & Bonding

1 – 9 of 9 Classroom Resources

• 

  Solubility, Solubility Rules, Solute & Solvent, Intermolecular Forces, Chemical Bond, Ionic Bonding, Covalent Bonding, Polarity, Intermolecular Forces, Intramolecular Forces | Middle School, High School

  Activity: Animation Activity: Solubility

  In this activity, students will view an animation that explores how ionic and molecular compounds dissolve (or don’t) in water. They 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.

• 

  Covalent Bonding, Ionic Bonding, Lewis Structures, Polarity, Ions, Electrons, Valence Electrons, Lewis Dot Diagrams, Electrostatic Forces | Middle School, High School

  Activity: Animation Activity: Bonding

  In this activity, students will view an animation that explores how different chemical bonds form. Examples of ionic, covalent, and polar covalent bonds are animated, and then students are given a sample of compounds to predict the bonding types.

• 

  Physical Properties, Covalent Bonding, Electronegativity, Polarity, Molecular Geometry, Intermolecular Forces, Solubility | Middle School, High School

  Activity: The Chemistry of Water Video Questions

  In this lesson, students will watch a video and answer questions about how the molecular geometry and polarity of water give rise to many of its unusual physical properties, including its relatively high boiling point and its ability to dissolve some substances but not others.

• 

  Physical Properties, Molecular Structure, Polarity | High School, Elementary School, Middle School

  Activity: What Makes Water So Special?

  In this activity, students will become familiar with the special properties of water by completing several activities that investigate the following physical properties/phenomena: cohesion, adhesion, surface tension, and capillary action.

• 

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

  Lesson Plan: Watch the Baby! Superabsorbent Polymer

  In this lesson, students will learn about how polymers, specifically superabsorbent polymers, work. Through lab activities, students will investigate polymer properties.

• 

  Polarity, Physical Change, Intermolecular Forces, Intermolecular Forces, Physical Change, Matter | Middle School

  Lesson Plan: Sandy Beaches—A Foray into ‘Magic’ Sand

  In this lesson, students will investigate the properties of magic sand and learn about the concept of hydrophobic and hydrophilic molecules. It also introduced students to the field of nanotechnology.

• 

  Polarity, Mixtures, Intermolecular Forces, Intermolecular Forces, Physical Properties, Observations, Mixtures | Middle School, Elementary School, High School

  Lab: Salad Dressing Science: Emulsions

  In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.
