Classroom Resources: Molecules & Bonding

1 – 5 of 5 Classroom Resources

• 

  Mixtures, Polarity, Observations, Physical Properties | Elementary School

  Demonstration: Colorful Milk

  In this demonstration, students will observe as the teacher creates several colorful mixtures. Using food coloring, water and milk, students will watch the colors swirl and mix. Students will have the opportunity to make a prediction about what will happen to the colors when a sample of soap is introduced to the mixture.

  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

  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**

• 

  Ionic Bonding, Covalent Bonding, Polarity, Molecular Formula | Elementary School, Middle School, High School

  Animation: Bonding Animation

  This animation 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. **This video has no audio**

  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.
