Each group needs:

• ball-and-stick molecular model building kit, available from many vendors such Frey Scientific
• paper and pencils, to create a compare/contrast chart
• Pre-Activity Quiz, one per student
• Lewis Dot Structures and Molecule Geometries Worksheet, one per student
• Post-Activity Quiz, one per student
• Blender Tutorial Step-by-Step Procedure, one per group
• computer with Blender software installed, open source 3D creation software, free at https://www.blender.org/; alternatively, use other CAD software you have available

To share with the entire class:

• computer with Internet access and projector, to show students two interactive simulations at https://phet.colorado.edu/ (requires Java) and a six-minute Blender software tutorial (or else students watch the latter on individual team computers)
• a 3D prototype of an atomic model of water, or any other example produced from a 3D printer, to show the class
• 3D printer
• ABS filament for 3D printing
• (optional) Visual Aid, contains graphics that you may want to project to show the class
