NSF STEM Day

The U.S. National Science Foundation (NSF) commemorated its 75th anniversary on May 10th, 2025.

The free event showcased some of the research projects, education initiatives, and public science communication efforts that the NSF has funded at Â鶹Ãâ·Ñ°æÏÂÔØBoulder and Â鶹Ãâ·Ñ°æÏÂÔØAnschutz. Â鶹Ãâ·Ñ°æÏÂÔØScience Discovery organized and led the celebration with its Build a Better Book partners at Mountain Lakes Library in New Jersey, Explora Science Center in New Mexico, Laredo Public Library in Texas, and Arecibo C3 Center in Puerto Rico. The celebration at all 5 sites included activities and demos for the public, young and old!

Â鶹Ãâ·Ñ°æÏÂÔØ (Main Internship site): Led the coordination, design, and dissemination of activities and experiences for STEM Day events and hosted a main event at the Engineering Center that showcases BBB intern projects and maker activities.

In the months before NSF STEM Day, Â鶹Ãâ·Ñ°æÏÂÔØScience Discovery BBB Interns recreated various projects created during their 2022, 2023 & 2024 Build a Better Book Summer Internships. Projects included laser cut accessible games - Ingenious and Chess and 3D printed Chess and Othello/Checker pieces. We disseminated the activities to our 4 partner sites for their NSF STEM Day celebration.

Activities at each site included:

  • Braille Embosser with text blocks that say "Build a Better Book"
  • Braille Twister dots
  • Braille Eggs
  • Braille Legos
  • 3D printed Braille Crayon caps, crayons and swell paper coloring pages.
  • Each site had a tactile laser cut map of their state and the public used fabric and craft materials to create a tactile map of their state.
