Information about the Lesson 

Title:

Structure Determines Properties

Brief Description:

Comparison of the structure of liquid water and ice, and how the hydrogen bonds in water explain its properties as a good solvent, and the fact that ice floats in water.

(time required to complete lesson, e.g. "two 45-minute sessions")

The lesson should be completed in approximately 20 minutes.

Goals:
(curriculum and unit related; National or State standards)

“Structure determines properties” is one of the twelve essential concepts identified by Irondequoit chemistry teachers

Objectives:
(measurable specific activities conducted by students)

.Students will visualize water using 3-D molecules, measure bond angles, and distance between atoms to increase their understanding of how structure determines the properties of water.

Procedures:

Read “Why Water is a Good Solvent,” follow links to water molecule, salt, and hydrogen bonding.

Measure distance between atoms and answer all multiple choice questions. Read “Why does Ice Float,” measure bond angles and distance between atoms and answer all multiple choice questions.

Assessment:

The multiple choice questions with immediate feedback should help students identify misunderstandings.

Special Comments:

Make sure you rotate the molecules. It’s fun and very helpful to see how structure determines properties!
