As part of a (hypothetical) challenge to help a city find the most affordable and environmentally friendly way to clean up an oil spill, students design and conduct controlled experiments to quantify capillary action in sand. Like engineers and entrepreneurs, student teams use affordable materials to design and construct models to measure the rate of capillary action in four types of sand: coarse, medium, fine and mixed. After observing and learning from a teacher-conducted capillary tube demonstration, teams are given a selection of possible materials and a budget to work within as they design their own experimental setups. After the construction of their designs, they take measurements to quantify the rate of capillary action, create graphs to analyze the data, and make concluding recommendations. Groups compare data and discuss as a class the pros and cons of their designs. Pre- and post-evaluations and two worksheets are provided.

This collection of videos, animations and documents comes from the NCSSM AP chemistry online course. Chapter nine provides practice and demonstrations related to chemical bonding and geometry.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"A new study from the Max Planck Institute for Human Development unveils the deep bodily connections that can form among choir singers Researchers tracked different physiological variables as a choir sung and used algorithms to uncover connections between them Aside from a blending of voices, they found that choir singers’ heart rates and breathing patterns sync up when performing as a group This merging was coupled to the vocalization patterns of the singers The conductor’s hand movements also caused a shared physiological response among the singers In essence, the work suggests that a choir can be considered a type of coherent physiological entity… or, as the researchers suggest, a superorganism Viktor Müller, Julia A.M. Delius, Ulman Lindenberger. Complex networks emerging during choir singing..."

This lab introduces basic chemistry concepts in molecular interactions, measurements, prediction, and critical thinking.

This course covers the fundamental concepts that determine the electrical, optical, magnetic and mechanical properties of metals, semiconductors, ceramics and polymers. The roles of bonding, structure (crystalline, defect, energy band and microstructure) and composition in influencing and controlling physical properties are discussed. Also included are case studies drawn from a variety of applications: semiconductor diodes and optical detectors, sensors, thin films, biomaterials, composites and cellular materials, and others.

This course focuses on the fundamentals of structure, energetics, and bonding that underpin materials science. It is the introductory lecture class for sophomore students in Materials Science and Engineering, taken with 3.014 and 3.016 to create a unified introduction to the subject. Topics include: an introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to atomistic and molecular models of materials; the role of electronic bonding in determining the energy, structure, and stability of materials; quantum mechanical descriptions of interacting electrons and atoms; materials phenomena, such as heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism; symmetry properties of molecules and solids; structure of complex, disordered, and amorphous materials; tensors and constraints on physical properties imposed by symmetry; and determination of structure through diffraction. Real-world applications include engineered alloys, electronic and magnetic materials, ionic and network solids, polymers, and biomaterials.
This course is a core subject in MIT's undergraduate Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

Students wear nametags of an ion and find others throughout the school with whom they can create ionic compounds.

This activity will take complex molecules and polyatomic ions the students have learned and construct them out of marshmallows and redhots. This develops understanding in VESPR structures and hybrid molecules.

This module is an introduction to using VSEPR to predict molecular shape based on Lewis structures.  It is limited to steric numbers of 6 or less.

This course focuses on the latest scientific developments and discoveries in the field of nanomechanics, the study of forces and motion on extremely tiny (10 m) areas of synthetic and biological materials and structures. At this level, mechanical properties are intimately related to chemistry, physics, and quantum mechanics. Most lectures will consist of a theoretical component that will then be compared to recent experimental data (case studies) in the literature. The course begins with a series of introductory lectures that describes the normal and lateral forces acting at the atomic scale. The following discussions include experimental techniques in high resolution force spectroscopy, atomistic aspects of adhesion, nanoindentation, molecular details of fracture, chemical force microscopy, elasticity of single macromolecular chains, intermolecular interactions in polymers, dynamic force spectroscopy, biomolecular bond strength measurements, and molecular motors.

An intensive survey of structure, reactions and synthesis of the main classes of organic compounds. Laboratory illustrates the preparation, purification and identification of organic compounds by classical and instrumental methods.

This course covers the principles of main group (s and p block) element chemistry with an emphasis on synthesis, structure, bonding, and reaction mechanisms.

This learning activity is designed to be used in a large introductory chemistry course, as part of a larger module of learning activities that includes prior viewing of an interactive instructional video. Instructional videos are to be viewed before class meetings. During class time, students work in small groups and discuss the presented information and question prompts, and will build upon the concepts discussed in that video in order to develop a new, extended concept.Students should be tasked with working together to complete the prompts in each section of the activity by a set time limit. After each section is completed, the entire class can share their answers via a personal response system, and the instructor can review and explain the correct responses, using the accompanying slide deck, which translates the problems into multiple-choice prompts.Instructional resources include 1) interactive instructional videos (these can be embedded directly into the learning management system) 2) the learning activity (.docx and .pdf) 3) the learning objectives (.docx and .pdf) and 4) the slide deck (.pptx). - Chemical Bonding- Resonance - Intermolecular Forces- Collision Theory- Equilibrium- Nucleophiles and Electrophiles
