Making Connections: playing with electrical circuits

Play-based, hands-on learning activities appeal to our creativity and our curiosity. When combined with specific prompts and tasks, they encourage children by providing greater success and a more rewarding experiences (McLean & Harlow, 2017) as they learn about the world around them.

Helping children to construct an understanding of scientific concepts “[equips] them to solve problems and address challenges that have a direct human impact” (Honey & Kanter, 2013, p. 2).

The approach posited in the McLean & Harlow study supports the increased emphasis on engaging girls in STEM learning. They found that when presented with an opportunity to create story or sculpture using the squishy circuits, girls were more likely to engage and learning outcomes mirrored those of boys.

Using inexpensive familiar materials, teachers can prepare simple, fun, yet challenging hands-on activities for their students that can also provide footing for learning down the road. By using the squishy circuits first, students play with concepts using materials that can be re-used multiple times. Following this play, they might then design and build a circuit using a given length of copper tape thus using design thinking skills, electrical know-how and mathematics. Turn that paper circuit into an interactive book, button or a card and you now have full on STEAM learning in action.


Make, Create, Innovate: Getting Hands-on with Learning Design

Recap of the session in the Scarfe foyer Fall 2019

Some people are frightened of electricity.

But when you combine a 9V battery with a handful of playdough and a few strategically placed mini-LED bulbs, anyone can safely learn the basics of circuitry. Before long, those same people might just take the lead, and soon enough they’re speaking knowledgeably about current, polarity, and conductivity and asking great questions of their own! More advanced students can extend their learning by co-constructing their understandings of series and parallel circuits, switches and more. Design challenges can support students creating toys and electrical devices or imagine the learning that might happen when high school chem students are challenged to create new recipes to increase conductivity or resistence and improve the texture, colour or consistency of the dough (McLean & Harlow, p. 128).

At this week’s Make, Create, Innovate! session, held Tuesday, September 17, 2019, Teacher Candidates (TCs) had a chance to learn about the basics of electrical circuitry by making squishy circuits and paper circuits.

By trying out these simple Science activities, TCs were experimenting and predicting just like scientists while also making connections to other subject areas, such as Math and Art. They were also developing an anchor for new ideas and concepts they might encounter later on, just as we try to do with young students.

Have a look at Mind Trekkers (Michigan Tech) and Beam (UCLA) for some lesson ideas, and check out Brain Pop for an assessment activity designed as an interactive web-based game. You can also find more about circuit-making activities at The Tinkering Studio (Exploratorium), Makerspaces.com, and STEAMsational, and you can download a helpful handout on “Circuitry Basics” from Instructables.

“Facilitating STEM events [allows] teacher candidates to recognize and listen to students’ science ideas” (Dani, Hartman, & Helfrich, 2018, p. 375)

At the same time they were making circuits, the TCs were sharing and co-creating their understanding by contributing thoughts and questions to an on-line virtual wall called Padlet, a web-based space for hosting and displaying collaborative communication and feedback in real-time.

Padlet lets users see their ideas update continually on a nearby TV monitor. It also allows people to respond to each other. It’s another simple way of using classroom-based technology to provide formative assessment by consolidating and sharing immediate feedback, which also helps to promote a classroom community of learning.

Learn more about Padlet on the Scarfe Digital Sandbox.

Interdisciplinarity, collaboration, hands-on learning – that’s the spirit of Create, Make, Innovate! We want to promote enthusiasm for sharing and learning across age groups and across subject disciplines.

Make, Create, Innovate sessions took place during the Fall 2019 in the foyer of the Neville B. Scarfe building and were hosted by Scott Robertson, a project assistant on a small TLEF grant with Dr. Lorrie Miller, Dr. Marina-Milner Bolotin and Yvonne Dawydiak, Teacher Education.

Paper Circuits

Paper circuits are easily constructed with different combinations of conductive material glued to or laid over paper. Materials may include conductive copper tape, conductive thread, insulated wires, paper clips, bulldog clips, pencil lead, virtually anything that allows electricity to flow. Combining these with 3V lithium batteries, LED lights, buzzers, etc. creates endless possibilities of circuits. Projects include light up badges, origami, greeting cards, bookmarks, you name it! We’ve even made origami paper circuit creations!


Why-is-it-relevant-360x82.png

Paper circuits are a great way to introduce and explore conductivity and electricity with children, in quick and fun projects, with practical and immediate results. With a range of materials to work with, it’s easy to get started. Projects can range from ‘follow the instructions’ to more inquiry based explorations.

Paper circuits activities allow students to problem solve, tinker around, and get creative by combining science concepts into art projects. When the LEDs light up, it’s guaranteed to put a smile on every face!


how-to-get-started-360x80.png

The materials may be obtained in dollar stores, hardware stores, or even online. Find some local (Vancouver area) suppliers and online suppliers here. Project cost if you purchase supplies in bulk is about $1.50 per project or even less!

LED lights light up just by clipping it over the 3V batteries, so from there on, the projects are really more about designing circuits using conductive and non-conductive materials to create paths for electricity to flow, and incorporating them into different paper objects. The challenges in designing should be fun and motivating to learners. You can find a lesson plan here: http://www.maketolearn.org/learn/lessons/led-pull-tab-circuit-lesson/

Arduino is a small open-source electronics platform that integrates hardware and software. The Arduino board can either be purchased online or borrowed from the UBC Woodward library. The software is available for free online for Windows, Mac and Linux.

Features include:

  • Hardware is inexpensive (between $5 and $40 depending on brand and where you purchase)
  • Software can run on 3 different operating systems
  • Relatively simple programming, good for beginners
  • Open-source software and hardware

Why-is-it-relevant-360x82.png

Arduino is a very useful tool for creating various interactive projects or just exploring programming and electronics. It is an excellent application to help students develop the core competencies of critical thinking and problem solving. With Arduino hardware an instructor can create various sensing equipment for a lab activity, like a sonar sensor, light sensor or even a humidity sensor and then use the software to run the equipment and show outputs. Using this technology would be a cost efficient and novel way of running a lab where students would be able to learn even more hands on things. Students could use the hardware to create a robot that they can then control by programming commands into the software. The process of assembling the hardware teaches many things at once: circuitry,  design and troubleshooting skills. Also working with the Arduino software is fairly straight forward and therefore perfect for learning how to code. There are an endless number of projects that can be created using the Arduino hardware and software, check some of them out by clicking here.
