Engaging 8- to 10-year-olds for an entire hour requires more than just talking and showing visuals; it calls for hands-on interactions. This age group thrives on activities that allow them to touch, think critically, and participate actively. To maintain their interest, break your presentation into short segments interspersed with interaction. While demonstrating elements like a traffic light or an elevator can offer insight into your work, it doesn’t foster meaningful engagement. Instead, consider transforming your session into an exciting contest.
Incorporate activities that may relate to your field or even basics from physics, such as building a tower with limited materials, constructing a bridge, or launching objects. Introducing a timed component can create a sense of urgency and keep the group on track.
Remember, engineers are problem solvers, so challenge them with relevant issues to tackle. When it comes to programming, it's important to involve as many students as possible. You could create a sequence of actions and ask the class to experiment and decipher the logic behind your code. For example, you might explain that pressing PB1 three times activates the green light, while pressing PB2 twice causes it to blink—but only if it's already on. PB3 could turn off the light when it’s blinking, and holding PB3 could deactivate the light if it’s steady.
Invite the whole class to brainstorm test scenarios, like pressing buttons multiple times or holding them down. Document their ideas on the board, and as they identify patterns, write those down too. Encourage the class to piece together the logic behind your programming, ultimately demonstrating how structured reasoning was used to develop the program. This interactive approach not only fosters engagement but also cultivates critical thinking skills in young learners.
Jaden suggested an engaging approach: How about incorporating an interactive element? I've been considering a setup using an infrared photo sensor to create a counting system, allowing students to walk through an "invisible beam" to be tracked. Would it be possible to include a brief video showcasing an automated machine? This idea resonates with me, and I believe interactivity is crucial for making learning enjoyable for kids. Standard concepts, like elevators and traffic lights, don’t capture their interest as much.
Building on Jaden's concept, why not turn it into a game? Think of a modern twist on "Red Light, Green Light." Instead of shouting “red light" or "green light," we could implement programmable buttons and lights. Students would press the red or green buttons, and if they reach the photo sensor while the light is green, they get counted; if it’s red, they’re out. We could also track how often the lights change and display that information on a small Human-Machine Interface (HMI) screen. Additionally, we could program various sequences for the lights, encouraging all participants to join in the fun!

**Engaging Young Minds: Keeping It Fast, Cool, and Interactive**
As dowthebow pointed out, the attention span of children aged 8 to 10 is notably brief. Having spent over 25 years as a scout leader, I can confirm that maintaining a fast-paced and interactive environment is crucial to keeping them engaged. Kids thrive on conversations with enthusiastic and engaging adults. This week, I'm collaborating with an engineering society to promote STEM education during Professional Engineer’s Week, targeting select eighth graders—typically math and science enthusiasts.
**Effective Strategies for Engaging Kids in Engineering:**
1. **Dynamic Slideshow on Engineering Basics:** Begin with a concise presentation explaining “What is engineering?” Help the audience recognize that nearly everything they encounter daily— from the alarm clock that woke them up to the breakfast food prepared using engineered products, the desks they occupy, and the clothes they wear—is a creation of engineering. Encourage participation by asking them to compile a list of these items on a board.
2. **Connect with Personal Interests:** If the discussion slows, prompt them to share their favorite toys or activities, then pivot back to how engineers made those experiences possible. Emphasize that life without engineers would be quite dull!
3. **Highlight Problem Solving Skills:** Guide the discussion towards the central role of engineers: solving problems. Explain that successful problem-solving not only contributes to society but also drives profits for companies, making engineering a lucrative profession. Sometimes, innovative solutions emerge to problems we didn’t even realize existed, such as personal computers and mobile devices that spawn new industries.
4. **Visual Impact:** In one of the slides, display the phrase “Engineers see things differently” using flipped or mirrored text for a striking visual effect. Contrast this with sports: if a professional basketball player consistently achieves a 75% free throw rate, coaches are pleased; at 90%, they are thrilled. Now imagine turning on a favorite toy or electronic device that only works 90% of the time—engineers strive for almost flawless performance, with zero tolerance for failure in critical areas like space exploration or water systems.
5. **Explore Engineering Disciplines:** Expand the discussion beyond traditional engineering fields such as Mechanical, Electrical, Civil, and Biomedical to encompass the various roles engineers play: design, manufacturing, testing, research and development, sales, service, project management, and computer/PLC hardware and software. Pose the question, “Does anyone know an engineer?” This inquiry usually sparks a few hands. Follow up by asking what these engineers do, revealing to students that engineers are more accessible than they realize.
6. **Broaden their Perspective on Career Paths:** Remind them that many engineers branch out beyond engineering roles. Numerous professionals, including patent lawyers, doctors, and business leaders, leverage their engineering backgrounds for diverse careers. Impress upon them that about 60% of Fortune 500 CEOs began their journeys with degrees in engineering, often progressing to an MBA.
7. **Incorporate Hands-On Activities:** Consider integrating a hands-on project or demonstration to spark interest in engineering. I recall an engineer father who created a Rube Goldberg machine for my 6th-grade classmate, harnessing potential, kinetic, chemical, and thermal energy to trigger a flashbulb. His explanation of the energy transformations captivated the students, creating a memorable learning experience.

Connect one of these robotic arms to your Programmable Logic Controller (PLC) and program it for automated pick-and-place tasks. Allow children to interact with the Human-Machine Interface (HMI) to directly control the robotic arm or modify the sequence of operations. You can find this model on Amazon: [OWI Robotic Arm Edge](https://www.amazon.com/OWI-OWI-535-Robotic-Arm-Edge/dp/B0017OFRCY). Although it is constructed from plastic, operates slowly, and has a weaker grip, it integrates seamlessly with PLC systems. For those willing to invest additional time and money, consider purchasing and assembling a metal robotic arm for enhanced durability and performance.
You never realize the impact you can make... I just wrapped up a session with a group of enthusiastic 8th graders (check out post #11) and was pleasantly surprised when one of the young ladies recognized me. She exclaimed, "You're the same person from last year's program! You're the reason I wanted to participate again, and I'm really interested in pursuing a career in engineering."
Last year, we had the students engage in a fun "computer programming" exercise where they created a step-by-step guide on how a "robot" (me) would make a peanut butter and jelly sandwich. They quickly understood the importance of being explicit in their instructions—otherwise, the robot wouldn't execute their intended actions accurately. For example, the initial command was to "drop the jellied slice of bread onto the plate that held the peanut butter slice"—all from about 3 feet in the air—with the jelly side facing up. As they observed the unfolding chaos, they wished they had an emergency stop button, especially when they realized what was about to happen. They had imagined the slices aligned perfectly at a 1-inch height, with the jelly side down and edges aligned within 0.25 inches, which led them to refine their instructions for the next sandwich.
It's clear why I made a lasting impression on her. This year's program featured a similar "programming challenge," but this time, we constructed a Lego car. It required significantly more steps and was much less messy. The key lessons remained: time management, effective communication, and teamwork towards a shared objective.
I introduced the concept of a light switch and a light bulb, providing a clear explanation for better understanding. We then engaged in an interactive activity where we created a human switch. In this fun exercise, the last person in the line represented the light bulb. When they were tapped, everyone enthusiastically shouted, "Light on!" - James.
MikeW remarked: In professional basketball, a player who successfully makes 75% of their free throws is considered satisfactory by their coach, but hitting 90% elevates them to elite status, prompting sheer joy from the coaching staff. Imagine if your favorite toy, television, or gadget only functioned properly 90% of the time—how would that make you feel? Engineers strive to design systems that operate flawlessly, aiming for nearly 100% reliability. In critical fields like aerospace and water management, where safety and health are paramount, any malfunction can be unacceptable, such as when recycling water that may have previously been sourced from sewage. If only our salaries reflected our performance ratios! Nonetheless, it's a fitting analogy.
I’m truly grateful for the incredible response to this thread! Thank you all for your support. I reached out to the teacher and found out that there will be several groups of children at different “stations.” This means I’ll be able to engage with smaller groups, although my interaction time will be shorter than expected—approximately 15 minutes each. This adjustment addresses the challenge of keeping their attention, but it also prompts me to consider what activities will be the most impactful during our time together. I’m glad I have a couple of months to get everything ready!
Please share your updates with us on how everything unfolds.
I recommend using a compact goal post attached to a stepper-driven linear actuator. The objective is for participants to throw a ball through the goal posts; however, incorporate a sensor to detect the ball's trajectory. This sensor will enable the goal posts to move sideways, creating a challenging experience that makes scoring a goal at throwing speed nearly impossible. This engaging setup will not only enhance the challenge but also provide a fun and interactive activity.
Last Friday, we held a successful STEM Day event that left a lasting impression on participants. Children from kindergarten to fourth grade were divided into more than a dozen groups, each consisting of around 8 to 12 students. Each group had the opportunity to engage in my session for about 15-20 minutes.
To make the most of this time, I created two interactive projects:
1. In the first activity, using six flat wood shims and four 2-inch steel squares, the students were challenged to construct the longest bridge possible between two small plastic containers (upside down). They faced the unique constraint that the bridge could ONLY touch the plastic containers—no support from tables, floors, or even themselves!
2. For the second project, inspired by Jaden's suggestion, I introduced a basic counting program utilizing a CompactLogix/PanelView Plus test kit provided by my local Allen-Bradley distributor. We started with an overview of various proximity and photo sensors, discussing their applications and importance. Then, I positioned a photo eye about a foot above the ground and had each child walk through the beam individually. Much to their surprise, the count doubled because the sensor detected each leg separately. This led to an enlightening discussion about the phenomenon. I then implemented an off-delay feature in the program, demonstrating how this adjustment resolved the issue of double counts.
The students asked insightful questions and made keen observations, showcasing the potential of several future engineers and technicians among them! Overall, the experience was incredibly rewarding, and I’m already brainstorming ideas for next year's presentation. I encourage anyone with a passion for teaching and the opportunity to inspire the next generation to seize such invitations and share their knowledge.
Thank you all for your valuable contributions!
I'm thrilled to hear that your event was a success! Back in March, I had a similar experience at my grandson's 4th-grade class for their "Career Day." I showcased a career in engineering through an engaging demonstration using a PLC (Programmable Logic Controller) and HMI (Human Machine Interface) setup. I included flashing lights, buzzers, and small motors to create a captivating experience. However, I did reveal my age when I mentioned I "wrote the program" for the PLC—kids today prefer to say they "code." Nonetheless, one student enthusiastically told me it was the coolest thing he had seen all day, even though I was competing with the local utility company, which was offering bucket truck rides.
