Safety goggles and hardhats are required at the Build It exhibit, where little sidekicks get tools (that’s right, mom) and an operational dump truck to help with these pint-sized structures. Over in Arts and Parts mini makers can can take part in a quick craft sesh with glue guns, awesome electric scissors, and new and recycled parts. The offerings extend to the outdoors, with a trike-and-hike loop, driftwood fort construction zone, chicken coop, garden, and more. hocm.org.
