Builder's Lab

Builder's Lab is the engineering counterpart to the Code Crew coding line. Each week presents a real engineering challenge: build a tower that holds a tennis ball five inches off the table, build a paper airplane that flies at least 10 feet, build a marble run that takes 5+ seconds. Kids design, build, test, fail, and iterate. Photos and timing logs are kept in a parent-shared notebook. Suitable for K-5 with parent guidance scaling.

• Sketch a design before building
• Test, measure, and record what happened
• Identify why a design failed (load, balance, friction, geometry)
• Iterate: change one variable at a time
• Compare two designs honestly using a measurement
• Explain a design choice in plain language
