ChemTube3D vs Kalzium

ChemTube3D is a free chemistry learning resource with interactive three-dimensional structures, animations, and supporting information. It covers organic mechanisms, organic structure and bonding, inorganic chemistry, polymers, and A-level chemistry for students, lecturers, and practising chemists. In a web browser, the JSmol viewer lets users manipulate animated structures. Organic reaction schemes show bond breaking and forming, charges, and lone pairs. Learning designs guide activities built around these visual models. Pages can be embedded in a learning management system or virtual learning environment through LTI; the site reports testing with Canvas and Blackboard, with the LTI tool supplied through OpenOChem. Free iOS and Android apps are available, with the iOS app offering selected Organic Chemistry and Structure and Bonding material. Selected transition-state models can be downloaded in STL and X3D formats for 3D printing. ChemTube3D also provides virtual labs, molecular modeling, and reaction simulation.
