Kick off the school year with Girlstart’s Back to School STEM Extravaganza! Join us for free and exciting science, technology, engineering, and math (STEM) hands-on activities for all genders and ages at the Girlstart STEM Center in Austin, Texas.

Check out Girlstart's booth at Del Valle's annual STEAM Extravaganza! Using craft sticks, rubber bands, and straws to design your very own sound sandwich instrument! Explore how you can change pitch by changing the vibrations, or the wavelengths, of your instrument. This event is open to members of the school district community.
