VSEPR Molecular Shapes Student Model Kits

Students visualize and represent molecules in 3-Dimensions. High quality plastic individual model kits for VSEPR configurations are used to enable students to build molecular models. Using an active learning approacah, given a molecular formula, students draw the Lewis Structure, Identify the total regions of electron domains around the central atom, build the model of the molecule, draw a 3D representation of the molecule, identify the molecular shape, identify the bond angles, and classify the molecule as polar or non-polar.

Intermolecular Force Activities Pure Substances and Mixtures: Parts I, II, III and IV

Activity Parts I and II: Students work in pairs to model intermolecular forces by labeling and manipulating plastic arrows and rectangles: General structures, IMFs in pure substances, IMFs in a mixture. Activity Part III: Students work in pairs by labeling and manipulating plastic arrows and rectangles with specific structures, or real compounds: KBr, ethane, ethanol, dimethy ether; identify IMFs in pure substances and IMFs in a mixture, place the arrow with the IMF to connect opposite charges.

Entropy ParaDice

A classroom set of two six-sided dice per student (one red and one white) provides an interactive activity that helps students to understand the nature of entropy.
