After opening its new "Nano" exhibit last week, ExplorationWorks in Helena welcomes the community to come check out that and everything else it has to offer at no cost today.

The exhibit on nanoscale science, engineering and technology includes hands-on exhibits that introduce real-world applications and explore the societal and ethical implications of the new technology. Free Day at the museum is scheduled for 10 a.m. to 5 p.m.

At noon, the community is also invited to join the Democratic Action Club at Lewis and Clark Library for a program on health care and climate change. Kim Abbott of the Montana Human Rights Network will discuss the Healthy Montana Initiative at noon and local Rhodes Scholar Aven Satre Meloy will address climate change at 12:30 p.m.
