From the telephone and light bulb to the computer chip and COVID-19 vaccine, scientific inquiry has birthed a plethora of society-changing inventions. As our reliance on technology of all kinds increases, it becomes more important for children to be science literate. And science fairs are a time-tested teaching tool. Locally, the Mendocino County Science and Engineering Fair will highlight the scientific explorations of students in grades 3–12. It will also include a family-friendly STEAM Expo that will feature an art gallery and hands-on activities for kids of all ages. The fair and expo are free and will be held on March 18, 10 a.m.–4 p.m., at Mendocino College in Ukiah. Volunteers and judges are needed. Contact [email protected] if interested.
