Introducing Atomic Tiles: an Exploration of Atoms and Molecules, designed by Dr. Seth Bush, Assistant Professor, Department of Chemistry, Cal Poly University, specializing in Chemical Education and developed by Dr. Fred Ventura, Ventura Educational Systems. Atoms are nature's building blocks. Everything is made of atoms. Atomic Tiles is an active learning tool where students explore how atoms come together to form molecules. Using Atomic Tiles students begin to understand the structure of atoms. Students learn that an atom has a dense inner core called the nucleus that contains protons and neutrons. The outer layer of an atom contains the electrons called the electron cloud. Most chemical properties properties of atoms, including how atoms bond to one another, are the result of the outermost electrons in the 'electron cloud' known as valence electrons. Atomic Tiles depicts valence electrons as open or closed circles, similar to Lewis Dots. Open circles are electrons that can be shared to form bonds. Closed circles are electrons that are not shared. Targeted Development of Science Concepts in the Following Areas: Atomic Structure - Neutrons, Protons and Electrons Valence Electrons - Covalent Bonding Properties of Elements - The Periodic Table of Elements Building Molecules - An Interactive Exploration of Molecular Structures

Dencity: AI Science Lab for Classes 6-12 (CBSE, ICSE, State Boards) Learn science by actually doing it. Dencity is a Virtual Science Lab for Classes 6-12, built to support CBSE, ICSE, and State Boards with interactive learning in Physics, Chemistry, and Biology. 400+ Interactive 3D Experiments in Physics, Chemistry, and Biology Explore 400+ experiments in a fully interactive 3D science lab simulator. Use the virtual lab to repeat experiments safely, test outcomes, and build strong understanding through practical learning. Step-by-Step Guidance with Theory Every experiment comes with step-by-step guidance and supporting theory, so students know what to do, what to observe, and why it works. Perfect for classroom teaching and self-learning. Physics: Change Parameters and See Instant Results Perform Physics experiments in mechanics, energy, thermodynamics, fluids, waves, optics, space concepts, and more. Change parameters, control objects, and observe real-time changes in outcomes inside the 3D lab. Chemistry: Mix Chemicals Safely in 3D Run Chemistry experiments without real-world risks. Mix chemicals, adjust quantities, vary concentration and conditions, and observe reactions in a controlled virtual lab. Interactive experiments make core chemistry concepts clearer and more memorable. Biology: Anatomy + Botany (Plants, Leaf, and More) Learn Biology through visual, interactive 3D learning. Explore Anatomy and expand into Botany topics like plants, leaf structure, and related life-science concepts. Observe parts clearly, interact with models, and understand systems with better clarity than static diagrams. Real-Time Calculations and Clear Understanding Dencity shows real-time calculations during experiments, helping students connect observations with the science behind them. Combine this with theory and interaction to strengthen conceptual clarity. Virtual Classroom Collaboration Teachers and students can join a virtual classroom, run experiments together, and transfer control seamlessly for guided learning, doubt solving, and collaborative exploration.
