STEM Programs in San Francisco, CA

In our STEM LEGO® class we use LEGO® bricks to teach concepts of science, technology, engineering, and mathematics (STEM) through a play-based model of learning. Kids construct a unique model each week using project instructions and LEGO kits. All models are interactive and classes are thematically linked to deepen and support a child’s understanding and vocabulary for STEM concepts. Each session covers new topics/subjects. Topics and discussions are geared for our younger TK, Kinders, and 1st graders. Free-play time rounds outs the class giving our students an opportunity to develop their creativity.

Get ready to make a little magic—and a whole lot of mess! In Sparkle & Splash, young artists will dive into three days of colorful, shimmering, and wonderfully messy art experiments. Campers will explore what happens when water, color, light, texture, and unexpected materials come together. They’ll splash, drip, mix, layer, sprinkle, swirl, and experiment with a variety of wet and dry materials to discover new ways of making and creating. There’s no step-by-step project and no “right” way to make. Instead, campers will be encouraged to follow their curiosity, experiment with materials, make discoveries, and let the process lead the way. This three-day camp is perfect for curious young artists who love getting messy, trying something new, and making art that shimmers, splashes, and surprises! 📅 December 28–30 👧 Ages 4–8 Children must be ready to follow safety guidelines and engage in their projects for 30 minutes or more.
