Empowering Students with STEM
Meet Hala Rivera Rentas, a passionate STEM teacher from Pasco County, Florida, who is transforming how students see themselves through hands-on building, coding, and invention. By using Strawbees and micro:bit, Hala empowers her students to become confident problem-solvers and young innovators — proving that with the right tools and encouragement, every child can succeed.

Background
Passionate is the word that could best describe Hala Rivera Rentas. Despite pursuing a Master’s Degree in Public Administration and a Doctorate in Business Administration, Hala had always been passionate about building and inventing.
“I was never the smartest in my class. If I got an A, it was a shock. I usually got C’s, sometimes B’s. I was really quiet and no one really saw me. But I was good at inventing. That was my thing.”
Since she was seven or eight years old, Hala has been inventing. She had her own Facebook page where she posted the robots she’d build with 3D printed parts and when she was first hired at Pasco Middle School, it wasn’t for business. After they learned about her enthusiasm for building, she was hired.
“It just felt meant to be. I never asked for this opportunity, but it came to me. And I truly believe this is a job I could do 24 hours a day and still be happy— especially when I get to do it with kids.”
Tinkering alone never appealed to Hala. As much as she loved inventing on her own, she found it meant a lot more when she was able to implement it in the classroom, especially with what Strawbees offers.

Implementation
All you have to do is ask Hala about the inventions her students have made with Strawbees and she can lead you on a full classroom tour of all of the things they’ve made – a helmet with a flower on top, a lie detector hat, robots of all sizes including one that dances when you clap, a dog that moves, a safe that will swat anyone that tries to take money from it...
A garbage can that automatically opens and a rock-paper-scissors game all made with the combination of Strawbees, recycled materials, and the micro:bit. And she would have even more inventions hanging from the ceilings of her classroom if it weren’t for the fire marshal.
“I challenged them one day to make a frog because the Strawbees frog is so cute. I love those frogs. I had all of them hanging from the ceiling but then I had to take them apart. The fire marshals didn’t like it though. But I did tell them that, ‘If you can recreate the frog, I’ll show the principal and you’ll get some candy!’ They loved the challenge.”
With Strawbees, Hala finds it easy to spark the competitive spirit in students. Giving them all of the steps and just telling them to do it could be too boring or overwhelming. She uses her own spark for creativity and invention to inspire them, even when they are intimidated by robotics and coding.
“I don’t just say ‘Make a robotic dog that walks and wags its tail’. That would overwhelm them. Instead, I say, ‘Build the body. Don’t attach the head yet. Let’s learn how to make the tail spin.’ Once we’ve coded that, then I ask, ‘Now, how would you attach this to the tail?’ And they can figure it out on their own.”
Lessons naturally build on each other. Kindergartners build simple shapes and then the first graders recreate what they built. Second graders add to it and write code. By third and fourth grade, they are working on themed projects – from silly trash cans, to alarm clocks to safes. By the fifth grade, they can explore more inventing.
“I realized that if I taught code step-by-step, I’d lose them. But if I presented it as a challenge, something competitive, they’d be all in. They’re smart and tech-savvy. I just show them the tools. I spread code snippets around the room, and they figure out how to put them together.”
Teamwork becomes natural as fast learners help others and the kids who need support get hints and help. With the help of Bobbi Starling in her district and the Strawbees team, Hala was able to take on her role effectively, and the way parents also feel proud of what her students create gives Hala even more passion in her role.

Outcomes
The student’s reactions and the change within her students has been the most noticeable for Hala.
“Sometimes I have students who don’t believe in themselves. They say, ‘I’m not smart,’ or ‘I’m not good at anything.’ But they’re amazing at problem-solving and being creative. And when they create something, I send them to the principal and she takes videos of them and these moments change the students. They start saying, ‘I’m an inventor. I can do this’. It makes them feel smart.”
One particular student with significant behavior and disciplinary issues caught Hala’s eye. She thought that if he had nothing to lose, then she needed to give him something he wanted to lose. She got the whole class involved and challenged him to build a robot and, if he could, the whole class would get a treat.
That spurred the students to encourage him to try and build something and even though he doubted himself, when the entire class clapped for him when he finished and when the principal took a video of him, Hala could see the change in front of her eyes.
“I saw his face– it was glowing. For the first time, he was proud of something he did in school. From that moment, everything changed.”
He started showing up to class on time and helping other students and his referrals stopped. There were still moments, but he was not the same kid. Once he saw he could succeed, he didn’t want to lose that feeling.
“That’s why I believe in what I do. It’s not just about coding or robotics—it’s about helping these kids feel seen, showing them that they’re smart in a way that maybe no one ever told them before. That they can build, lead and invent.”
Hala knows not just through one student but through many that all they need is someone to believe in them first and show them that they have something special inside. That’s what she tries to do every day. When they realize it, Hala says that it’s magic.
“I’ve realized how long-term this impact is. This isn’t just a job— this is a message. I’m here to motivate them. That’s why I love this job.”
