Nationally aligned
Not just making.
Engineering thinking.
Every activity connects the challenge, student evidence, and assessment to NGSS Engineering Design. ITEEA STEL connections are added when they meaningfully support the work.
3-5-ETS1-1
Define
Identify a need, criteria for success, and project constraints.
3-5-ETS1-2
Develop
Create and compare possible solutions using the criteria.
3-5-ETS1-3
Improve
Fair-test a prototype and use evidence to make it better.
The E-Fabrication lab
Ideas become
real objects.
Students may combine cardboard, paper, craft materials, reused objects, simple circuits, coding, sensors, and any lab machine that genuinely improves their idea. Every challenge welcomes more than one solution, with adult-operated fabrication steps, safety guidance, and no-machine alternatives.
