Happy Atoms is the physical and digital teaching tool that lets you discover the world of molecules in an intuitive, hands-on way! This interactive learning tool combines a digital app with a physical modeling set that lets students from 4th grade through college approach chemistry from a different angle. Happy Atoms requires the use of the Happy Atoms modeling set for full play. The sets are available at www.happyatoms.com and at many educational retailers! Chemistry is an incredibly important subject that many students never fully grasp. Knowledge of chemistry is necessary to solve many real-world problems, but the way chemistry is taught now often fails to capture students’ imaginations, discouraging experimentation and discovery. Happy Atoms aims to change that by offering a chemistry learning experience that sets itself apart. * See the difference between elements * Feel the forces that bond them together * Experiment with ways to combine them * Discover the relationships between molecular structure and properties To report issues and support please email: support@happyatoms.com Funded by the Institute of Education Sciences U.S. Department of Education (ED-IES-15-C-0025)

From elementary school through college, VEXcode is a coding environment that meets students at their level. The intuitive layout of VEXcode allows students to get started quickly and easily. VEXcode is consistent across Blocks and Text, across VEX IQ and VEX V5. As students progress from elementary, middle, and high school, they never have to learn a different blocks, code, or toolbar interface. As a result, students can focus on creating with technology, not trying to navigate a new layout. Drive Forward is the new Hello World We all know that robots attract kids to learn. VEX Robotics and VEXcode are providing opportunities for students of all ages to participate in learning the code that makes these robots work. VEX makes computer science come to life through collaborations, hands-on projects, and engaging experiences. From classrooms to competitions, VEXcode helps to create the next generation of innovators. Drag. Drop. Drive. VEXcode Blocks is the perfect platform for those new to coding. Students use the simple drag and drop interface to create functioning programs. Each block's purpose can easily be identified using the visual cues like its shape, color, and label. We've designed VEXcode Blocks to allow those who are new to robotics to get their robot up and running faster. Now, students can focus on being creative and learning computer science concepts, not stuck trying to figure out the interface. More accessible than ever VEXcode even helps across language barriers, allowing student to read blocks and comment programs in their native language. Drag & Drop. Powered by Scratch Blocks. Students and Teachers will feel instantly at home with this familiar environment. Video Tutorials. Grasp concepts faster. Built-in tutorials cover every aspect needed to get up to speed fast. And more tutorials are coming. Help is always there. Getting information on blocks is fast and easy. These resources were written by educators, in a form both teachers and students will grasp quickly. Drivetrain Blocks. A breakthrough in simplicity. From driving forward, making precise turns, setting speed, and stopping precisely, VEXcode makes it easier than ever to control a robot. Setup your VEX robot. Fast. VEXcode's device manager is simple, flexible, and powerful. In no time at all you can setup your robot's drivetrain, controller features, motors, and sensors. 40+ Example projects to choose from. Jumpstart your learning by starting with an existing project, covering every aspect of coding, controlling robots, and learning to use sensors.
