MANCHESTER, NH – The New Hampshire 4-H Science Bonanza will be held virtually on Saturday, December 12, 2020, from 9:00 a.m. – 2:00 p.m. This free event provides numerous ways for youth to explore STEM from their homes! A combination of pre-recorded and live videos will be available, and registration is required. Live events on December 12, via Zoom, will include:

  • 9:15-10 a.m. — Build your own Crankie (Kinetic Sculpture) for families; young children will need adult supervision
  • 10-10:45 a.m. — Pandemic Response: Quarantine Box Design for grades 6-8

Activities will require materials; some materials will likely be on hand (glue, scissors) but families should plan to prepare materials in advance and purchase items, if need be, like seeds for the hydroponics workshop.

In the week following the NH 4-H Science Bonanza, pre-recorded videos will be released through UNH Extension’s 4-H Science Bonanza website about knots and pulleys, insect communication, maple syrup, the 4-H STEM Mars Base Camp Challenge, building your own hydroponics unit and the non-Newtonian fluid oobleck!
