# Molecular Modeling for K-12 -- A STEM Activity

-------------->spin on -------->- spin off
------>space fill/cpk -------->stick ----> ball-and-stick

The following activities were originally used to complement the Middle School Physical Science curriculum. But are also ideal for an introductory Chemistry class or for those just interested in learn about molecules. The original activities required the software Chime to be downloaded to each computer to run the activities. The activities went online with the introduction of Jmol, and currently are used being updated on World of Molecules using Jsmol which allows students to work directly online with either Mac or PC computers or laptops. Most activities use Javascripts to allow assessment. All these pages are also mobile ready!

### Part I: Introduction to Molecular Modeling

Using water, methane, aspirin, and ethanol atoms. Learn about chemical formulas for the basic hydrocabons and view online. Activity contains online assessment.

### Part II: Crystal Structures.

Learn about Ice structure... Graphite vs. Diamond...Salt vs Calcite.

### Part III: Activity Sheet

Activity Sheet for Introduction to Molecular Modeling. Questions which can be turned in to teacher when done as a class activity.

### Part I: 1Dimension, 2 Dimensions, 3 Dimensions

In this lesson we will take a look at the 3-Dimensional world we live in.

### Part II: Measuring Bond Distances and Angles in Molecules

Using Jsmol students will learn how to measure distance and angles in water and carbon monoxide and see relationships with mathematics.

### Part III: Geometric Structures in Molecules

Activities show geometric comparisons of molecules such as ice and methane to tetrahedrons. Molecules also include benzene and buckeyball.
