Last Wednesday, 32 workshop students split up in groups and received a bag with an LED, a battery pack, batteries, & alligator clips. No instructions. Out of the 7 groups, 5 presented me with a lit up LED, at which point they got 2 more LEDs & several more alligator clips....~20 students in K-5th grade worked collaboratively to construct series circuits using good old curiosity. Unfortunately, the other 2 groups were doing everything right with no luck. Even with brand new batteries & LEDs (possibly old battery packs) through no fault of their own got frustrated and asked to stop. Most of them ended up sewing.
Lesson learned by me: test ALL the material next time - I didn't test all the battery packs.
