Group Kit
Everything a class needs to build circuits at 10 stations at once, packed in a sturdy plastic carrying case. With up to 3 students per station, one kit serves a class of up to 30. Dough is not included: add 2 Dough Kits or the Group+ Refill Kit.
What students can build and learn: simple, series and parallel circuits, conductors and insulators, and sound and motion with buzzers and motors. Free NGSS-aligned lessons are on our Education page.
What's in the box
- 10 battery holders (each takes 4 AA batteries, 40 total, not included)
- 10 piezoelectric buzzers
- 10 motors with fan blades
- 10 switches
- 80 LEDs: 10 each of red, green, white, yellow, orange, purple, blue and color-changing
- Plastic carrying case
Options (the dropdown above the button): add 2 Wired LED Assortments, or swap the 10 battery holders for 10 USB Power Hubs and 2 USB-C transformers so there are no AA batteries to buy. Both together is the $475 option.
Good to know
- Each battery holder takes 4 AA batteries (40 total), not included. The Power Hub options need no batteries.
- Recommended for ages 8 and up. Younger children can use it with adult supervision.
- The dough is non-toxic but contains wheat (gluten). Keep the conductive dough sealed in its tub or it dries out. The white insulating dough does not dry out.
- Tested to the ASTM F963-23 toy safety standard (Eurofins, 2026).
