With the Lewis Structures and Molecular Geometry Guided-Inquiry Chemistry Kit, students draw Lewis structures to predict molecular geometry. Then, molecular models are analyzed to visualize molecules’ shapes, and 3-D structures are sketched.

Molecules have fascinating shapes and patterns! The structure and shape of a molecule influence its physical properties and affect its chemical properties as well. Lewis structures and VSEPR theory offer useful models for picturing the structures of covalent compounds. Students practice drawing Lewis structures of specific molecules, and use these structures to predict their molecular geometry. Students then examine molecular models to visualize the shapes of molecules and sketch their three-dimensional structures.
Words and pictures on a printed page are no substitute for models that students can hold in their hands, rotate, turn upside down and even take apart and put back together. Students develop spatial reasoning skills required for success in chemistry as they discover how atoms join together to make molecules. Includes all the parts needed to assemble all eleven structures shown in the photo along with reproducible student handouts, detailed background information and Teacher Notes with sample data and answers to all questions.
Super Value Kit is complete for 15 student groups. All materials are reusable.
