Walder Science

Coding Crash Course

Welcome to the Home Learning Coding Crash Course! This course is a great opportunity to learn the basic concepts of coding at home, while schools are closed due to COVID-19.  By the end of the course, you should be able to create your own animations and simple games using the Java programming language. This course is for beginners who are comfortable reading and typing. Recommended age group is 6th grade and up. The course consists of 4 weekly video lessons, each approximately 10-15 min long. Each video lesson is accompanied by a detailed handout and coding challenges (linked under each video) that would take approximately 45 min to 1 hour to complete.  

You will need a computer and an internet connection to download the program and to download the course material. But internet is not required to work on the coding challenges. Students who submit their projects (based on the coding challenges) will be entered into a weekly raffle to win prizes. You can email us your projects to programs@walderlab.org in form of a screen shot, a video, or the source code, or you can upload your creation to openprocessing.org and send us a link to view it there. Please provide student's name, school, and grade level when submitting your answers. Happy coding!
