STEM Enrichment Programs for San Antonio Kids

STEM enrichment activities San Antonio after school weekends

Enriching Lives

After-school or weekend enrichment programs, including STEM enrichment activities, offer children the opportunity to discover new interests, develop new skills, hone existing talents, and learn valuable life lessons. San Antonio is home to plenty of places where children of all ages and backgrounds can explore their world. The best part? Many of the city’s programs are free! In this four-week series, we will showcase activities designed to engage everyone from the preschool Picasso to the high-tech teen and every nature lover, sports enthusiast, and animal activist in-between. Read part two on arts enrichment, part three on outdoor enrichment, and part four on volunteering..

Learning STEMs from Play

Our children live in a high-tech world and learning how to live, work, and play within its structure will be paramount to their future. STEM enrichment programs (Science, Technology, Engineering, and Math) offer children of all ages the opportunity to learn advanced concepts using modalities that get them motivated and keep them interested. Video game programming, LEGO construction, robotics, and simulated space missions are just a few of the ways that STEM programs meet children where they live, teaching them valuable, marketable skills hidden within fun, engaging play. You know, kind of like sneaking veggies into their favorite baked treats.

Codeword FUN

In the global world of technology, coding is the universal language. Teaching children to be fluent in that language through video game design is what Code Ninjas is all about. With a focus on Java Script and C Sharp programming, the program is open year-round to children ages 5–18. Code Ninjas Stone Oak Center Director Tyler Radtke says that for those parents who think their children spend too many hours gaming, Code Ninjas provides an excellent alternative by allowing them to learn through their favorite pastime.

“Here they build games, test them out and play them, but they are also learning how coding affects the different aspects of the game from design to function and animation,” he explains. “It is the best of both worlds.”

Children ages 5–7 are considered Junior Programmers and they follow a structured group format. They begin by learning a concept such as algorithms, defining it, and then experimenting with practical applications. Once they master the skill, they take part in Code Spark, implementing what they have learned into a simple game.

Children ages 8–18 participate in a self-paced, individual program where they progress through the ranks, martial arts style, from a white to black belt, learning different skills and coding languages along the way. Each instructor, known as a Sensei, is ready help guide students through the process. Upon reaching black belt status, the student builds a game from scratch utilizing all the skills and coding techniques he or she has learned.

“Tech is only going to become more integrated into our everyday lives,” predicts Radtke. “By providing kids with an opportunity like gaming, that they enjoy, we are giving them experience and knowledge in a language that could ultimately change their lives.”

DoSeum STEM enrichment activities

Learning by DOing

At the DoSeum, San Antonio’s museum for kids, it’s all hands on deck as children explore STEM concepts through interactive structures and programs designed to stimulate little minds.

“Museums like the DoSeum specialize in engaging young learners in STEM, and in foundational skills and concepts fostering literacy and numeracy,” explains Daniel Menelly, CEO. “We contextualize these ‘big ideas’ through hands-on/minds-on learning and creative play. We feel that curiosity and wonder are the powerful first and second gears of learning.”

Immersive story spaces, interesting and accessible design challenges, and thoughtfully engineered climbing structures invite children to problem solve through play while allowing each child to define his or her interests and explore at an individualized pace.

From “Big Days of Play,” to “Family Workshops,” to “Tinkerfest,” and the inventive and always-evolving daily programming, there is something for every child to discover and learn. There is even a “Little Do-ers” pre-school program.

“The variety of options we offer ensure ample opportunities for personalized and self-directed learning,” describes Menelly. “We encourage our young learners to map their own way through the DoSeum’s exhibit halls and yards. In the process of choosing where to play and what to try, we see young learners defining themselves as adventurers and explorers.”

Out of This World

There’s nothing like staring up at the vastness of a starry night sky to unlock the imagination. At the Scobee Planetarium, that’s exactly what is encouraged at the Challenger Learning Center.

“Many children are fascinated by space,” says Michelle Risse, Planetarium Coordinator. “We are putting them in scenarios where they can be engaged and learn.”

In the Micronaut Program, little astronauts ages K–2 can take part in a simulated space mission complete with hands-on activities and story-times. Beginning in third grade, those missions change to more in-depth experiences including setting up a colony on the planet Mars. These programs are designed for field trips and enrichment activities for groups of 20 or more and are ideal for class field trips or home school groups who are looking for STEM enrichment activities.

“Technology is all around us so introducing kids to the idea of using technology and thinking outside the box to problem solve helps them in every aspect of life,” says Risse. “They don’t have to go into a STEM field as adults to benefit from what they learn.”
