Triangle du feu
À l'aide d'une bougie, les élèves mènent quatre expériences pour supprimer l'un des côtés du triangle du feu (l'oxygène, le combustible et la chaleur) dans l'optique de comprendre les éléments indispensables au feu. Ensuite, à l'aide d'une plaque métallique, ils observent la flamme d'une bougie pour étudier la combustion.

Transfert de chaleur et déclenchement
Les élèves font part de leurs observations sur les modes de transfert de l'énergie thermique et sur le départ du feu au contact de la chaleur. Les élèves comparent le rapport surface/masse d'un morceau de bois et d'un cure-dent, puis ils comparent leur propension à s'enflammer. Ils décrivent ensuite comment les différents matériaux s'enflamment et brûlent.

Hoverboards, Drones, Electric Bicycles, & Beyond
UL 2849 initially addressed safety standards for electrically pedal-assisted (EPAC) cycles. But with the increased popularity of e-bikes, e-motorbikes and e-scooters, UL 2849 has been updated to include all roadworthy cycles, not just EPACs. The third edition of the standard addresses the most recent issues to support safe use of any product intended for a single rider or possible passenger that is typically considered for road use, may have pedals, and is typically sat upon during operation.
