Kids Programming Classes
Lego Robotics

Welcome to wonderful world of robots! Students immerse themselves in STEM learning, while they build Robots using Lego and learn programming on a graphic user interface. Progressive courses teach students a wide range of skills and STEM concepts.  

Grade 1 to Grade 6
Lego Camps Chantilly

Electronics can be a complex topic to teach, but not so at Science Cosmos. Students learn the fundamentals using an easy to understand system with snap-circuits and then progress gradually to higher levels, to learn more advanced concepts using the ardurino platform.

Grade 2 to Grade 6
Lego Classes Ashburn
Minecraft STEAM & Game Design

Children love to play video games. Why not show them how to create their own games instead? Children learn STEAM Concepts with our Minecraft (Education) Course, where they learn creativity and problem solving in a fun way. Besides Minecraft we teach game design, using the Scratch and Kodu platforms

Grade 2 to Grade 6
Lego Classes Chantilly

Whats a better way to learn STEM concepts, than building Lego Based structures and machines, that relate to everyday life.  Our students enjoy this as much as the Lego Robotics Courses. They are free of the distraction from the computer, and are able to immerse themselves into building. Students comprehend concepts related to simple machines, engineering, while experiencing a sense of accomplishment with their creativity.  

Grade Pre-K to Grade 6
Lego Robotics Ashburn
Math Hands-On

Did you know that kids comprehend Math better if they can visualize better. We bring this idea to reality with our hands on Math programs.  Students live in a 3D world, so isn't it logical that they learn Math concepts by manipulating and building with 3D objects? We have math courses based on Lego, Knex and other manipulatives. 

Grade 1 to Grade 6
