Middle School Chemistry: Lesson Plans: Water Is a Polar Molecule
Students develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.

Concord Consortium: Molecular Workbench: Water Molecules & Carbon Nanotubes
View this simulation to observe how water molecules move through carbon nanotubes.
Museum of Science
Miami Museum of Science: Making Water Molecules
This simple lesson involves making a model of a water molecule from gumdrops. A toy car is also used to explain how a model compares to the real thing.

Ucar: Just a Phase: Water as a Solid, Liquid, and Gas
This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

Concord Consortium: What Happens to the Energy of Water Molecules During Hurricanes?
In this investigation students will add energy to the model of how molecules interact by completing the following activities. Activity 1 What does boiling do to water molecules? Activity 2 How hot can water go? Activity 3 How does energy...

Middle School Chemistry: Lesson Plans: Why Does Water Dissolve Salt?
Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.

Concord Consortium: Molecular Workbench: Water and Polar Substances
Adjust amounts of ionic charges in this simulation to see how water molecules react to polar substances in solution.

Middle School Chemistry: Changing State: Evaporation
Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.

The Concord Consortium: Molecular Workbench Micelle Formation
Watch how micelle formation changes in a solution with water compared to a solution consisting of oil.
Utah STEM Foundation
Utah Stem Action Center: Salt Dissolved in Great Salt Lake
In this lesson, students will compare water from a fresh lake to water from the Great Salt Lake to begin to build a conceptual model for how salt dissolves in water. The lesson focuses on students using and developing models of molecules...
