The second annual STEM Expo, an offering of the Enumclaw Schools Foundation in partnership with the Enumclaw School District, will take place from 4 to 8 p.m. Thursday.

STEM is an acronym for science, technology, engineering and math. The Expo, which takes place in the Enumclaw High commons, is designed to excite young people about careers in those fields.

The free event, with the theme “Spirit of Innovation,” brings together teachers, students, families and businesses to showcase various high-tech activities and industries that are growing and providing jobs for those with the right skills.

Last year’s STEM Expo attracted more than 1,000 guests.

Earlier in the day, the Enumclaw Rotary Club will sponsor a STEM Expo luncheon at the Enumclaw Expo Center fieldhouse.

The keynote speaker will be Jeffrey Charbonneau, 2013’s national teacher of the year, who will share his thoughts related to the interactive teaching of science and technology. The luncheon also will feature a demonstration by NAO, the most widely-used and advanced humanoid robot for academic purposes in the world. In addition, Enumclaw Superintendent Mike Nelson and district teachers will share information about recent advances in STEM programs and high-tech equipment in the school district.
