Choose from these STEM Programs

Lights & Lasers – Explore our darkened Physics Lab, where rainbows sparkle and stars glow in the dark. Experience a variety of colored light demonstrations. Watch as energized gasses glow with their own unique and colorful displays. Learn about different lasers, see how they interact with various substances. Finally, guests will make an energy bead bracelet or glow worms (birthday family chooses when booking party). Appropriate for ages 5 – adult.

Stars & Constellations – Enter our darkened physics lab, where guests will see glowing and sparkling stars energized by KOSC’s black-lights. Learn about what’s visible in the night sky around your birthday! Finally, guests will make a star-finder that they can take home. The star-finder is a movable map for locating stars and constellations in the sky throughout the year. Appropriate for ages 6 – adult.

LEGO SPIKE Robotics – Create robots using LEGO! In this highly interactive program, children will use the innovative LEGO SPIKE platform to build and program robotic sets! As time permits, guests will have the opportunity to reprogram their projects to change their movement and their sounds. Appropriate for ages 7 – 12.

Air Rockets – Rockets are a blast at KOSC! At the start of this popular program, watch footage of NASA rocket launches. Then, build your own paper rocket and launch it into the sky. These rockets are easy to make but they fly well and can achieve altitudes of up to 100 feet! After the launch, guests can retrieve their rockets and take them home! For the grand finale, the birthday person will get to launch one of KOSC’s high-flying Estes Model rockets. Appropriate for ages 7 – adult.
