Synopsis

This resource introduces a simple lesson of cardmaking with electrical circuits. STEM & STEAM focus. The project – a greeting card – includes cardboard, and an elementary electrical circuit running on 3 Volts (coin battery). The sticky copper strip circuit for the card involves the 3-Volt battery, a Led (light), and a switch. Arts and crafts are used to create the artwork – for example, watercolours, ink sketching, and more. The resource then progresses in discussing more advanced digital components like microprocessors (Microbit, Picaxe, Raspberry Pi, and Arduino). These sophisticated electronic devices could be included to produce a greeting card with more functions or a next project. The lesson encompasses integrated learning, critical thinking and global citizenship. A Tinker Space – located in the corner of a classroom – would be most beneficial so students can experiment with their ideas. Essential hand tools (scissors, pliers, side cutters, etc.) and a soldering station would be required for tinkering and creating quality projects. The focus is on Junior high school Design and Visual Communication, Technology and Digital Technologies. However, the resource is suitable for senior-primary school students.

THE BRIEF

Situation: You are interested in simple electrical circuits. You have an idea to create a greeting card that contains some 3-volt electricity (‘coin battery’). Use LED lights to light up some of the artwork on the card. Switch – when you bend the corner of the card the copper tape will, make contact with the battery and turn the LED on. See the videos and instructions in this lesson for details on the assembly of the card and the switch.

Brief: Design and make a simple greeting card with a battery and LED light. For example, a BIRTHDAY CARD.

Specifications:

·        SIZE OF CARD: Standard size greeting card (about 100 mm x 150 mm). Typical Merry Christmas or Happy Birthday card.

·        COMPONENTS: Sticky copper tape (5 mm wide- peel back off), battery (3-volt) to back of card with a LED light, and LED light switch (bend corner – bottom right).

·        A MOCKUP CARDBOARD CARD WITH A DIAGRAM SKETCHED ON THE BACK: This is part of the planning – make one and see how it will work. Ask the stakeholder (teacher and/or a friend in class) how you could improve. If you have made a mistake (or something is not working out ok) type up the modifications. You get credits for this process of typing up the modifications. The heading for this step is: ‘Modifications to my mock-up greeting card.’ Everything you do must be documented in Google Docs (Google Slides). Share with the teacher on Google Docs.

·        PLANNING: Plan and draw the circuit on a separate piece of paper first

·        ARTWORK: Create artwork at the front and middle of the card. Media of your choice: pro-markers/water-paint/acrylic paint/colour cardboard/soft pencil/etc. You could do this in the Art class – ask your Art teacher permission.

·        COVER FOR THE ELECTRONICS (TO MAKE IT LOOK TIDY): Double-sided tape and cardboard as a backing (cover) to the back of the card (‘lid’). To cover the electric circuit and components

·        ENVELOPE: Make a simple envelope for the card. Use drawing paper – available in class.

THE LAYOUT OF YOUR PRESENTATION, INCLUDING THE GREETING CARD:

·        Do research on simple electrical diagrams – paste it into a Google Slide or Doc

·        Do research on copper tape & LED greeting cards – paste it into a Google Slide or Doc

·        Design your mock-up on a brown cardboard card (testing your ideas). Draw the diagram on the back and plan your artwork on the card.

·        Share your card with a friend or the teacher

·        Type up the changes, improvements, and modifications.

·        Cut the final greeting card from white or coloured cardboard. Size: about 130 mm X 200 mm

·        Design your card – copper tape, LED & battery (circuit). Write your message on the inside and the main label in the front. For example HAPPY BIRTHDAY or MERRY CHRISTMAS.

·        Draw your electrical diagram at the back of a piece of cardboard greeting card size

·        Plan and do the artwork (front, middle and back)

Background of the incandescent bulb and LED lights:

We all probably know the humble incandescent light. The older generation grew up with the incandescent light bulb (1920 – to 2005). An incandescent light bulb is the typical round bulb type with a filament that glows very hot – burning to the touch. Most probably, you have one in the bed lamp next to your bed, or you could have one in the centre of your ceiling in your bedroom.

It was a health and safety hazard. Parents and caregivers used to be very careful around these bulbs with children. Touching a bulb could cause severe burns. A LED light is always cool to the touch because it only emits light and no heat. That is why it is so energy efficient! I remember shaking the old type of incandescent bulb lightly, and then I listened if the filament was loose or broken off on the inside. The clear glass bulbs were very easy to inspect. One could see if the filament was still intact. Most people still draw an incandescent bulb above a person’s head to illustrate that the person got a great idea or was enlightened by something. I wonder how we will draw an LED in sketches in future, to illustrate an enlightening moment.

I remember years ago when the CFL (compact fluorescent light) became available as new energy-efficient lighting technology. It was about 1995 – if I remember correctly. It is amazing how lighting has evolved over the past ten years; so energy efficient now.

I remember changing the incandescent light bulbs, and spiral-shaped CFL’s in my own home in 2015 to LED’s – the power bill dropped significantly after the switch! I realised the enormous amount of energy a country could save if all its citizens change to LED lighting. It is these small strategies on sustainable practice that excites me. Education is the key. We can effectively take action for the environment. A great way to enthuse students to take action for the environment is by making them aware of possibilities and strategies to save our precious resources. LED’s are one such area. Students – as global citizens – can run awareness campaigns on LED lighting at school to make a difference.  

WHAT IS AN LED LIGHT?

A light-emitting diode (LED) is a two-lead semiconductor light source. A p–n junction diode emits light when activated. When a suitable voltage is applied to the leads, electrons can recombine with electron holes within the device, releasing energy in the form of photons. In simple terms, a ‘chip glows.’ No heat is emitted – cool to the touch.

ENERGY EFFICIENCY OF LED’S

The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionised energy-efficient lighting. CFLs are simply miniature versions of full-sized fluorescents.

WHAT IS A DYNAMO?

A dynamo is a machine for converting mechanical energy into electrical energy, typically using rotating coils of copper wire in a magnetic field.

TEACHER SHARING HIS MEMORY OF A DYNAMO: I can remember my first encounter with a dynamo many years ago. I was a young primary school student when I saw an African man used a dynamo on his bicycle. The dynamo was installed on the frame of his bicycle, and the wheel touched the tyre. The power generated by the dynamo light up the headlamp, which was installed in front of the handlebars.

Teacher’s experience with teaching students about LED’s:

LED lighting is an excellent method to introduce students to electronics. The introduction to LED’s is very simple and straightforward and can be taught to primary school students. As most teachers are aware, kit sets are available for Technology Projects. Doing a simple electronics project including lighting and sound will entertain students. Project-based learning and student-led learning is an exciting avenue to explore.

With the continuous development of new products and the invention of new ideas, there are just so much to choose from. ‘Poetry on Paper,’ is a relatively new development where copper wires, plates and strips are combined with lighting, sound components and more to produce art. This idea allows students to express their individuality and allow the students to be creative and innovative. For an extension into literacy, the ‘artboards’ could tell a story. It means students could write an innovative, creative story using a range of electronic artboards – almost like a children’s illustrated storybook.  The sticky copper tape is used to create circuitry effortlessly. No need for soldering is required. However, simple soldering is an additional skill – proving lots of fun – that could be included. Very cost-effective project-based teaching strategy!

See the website of Exploratorium for excellent ideas! Make simple or complex electrical circuits on a flat piece of paper! Using copper tape and surface-mount LEDs allows you to make a fully functional circuit on a flat surface, like a piece of paper. You can make light-up greeting cards, make origami animals come to life, or create three-dimensional pop-up paper sculptures that have working lights in them. Great to teach sustainability, sustainable architecture, and more.

INTEGRATED LEARNING

Students love having fun with circuits, LED lights, switches, buzzers and microcontrollers.

Once students have mastered the basics, there is just so much more to explore. In this project, I will discuss a simple GREETING CARD project. The project can be described as a simple paper card with artwork in front and ‘hidden’ circuitry at the back of the card. The component, in brief, is sticky copper tape, 3 Volt battery, simple switch, LED light, and a microcontroller (optional) that allows the LED light to flash for example.  Just the basics are described here. Teachers and students can develop the idea and refine it.

The greeting card is a great project for INTEGRATED LEARNING! The Maths, Science, Technology, Fine Arts, Design and Visual Communication, Accounting, Digital Technology, Business & Entrepreneurial Studies, and English teacher could all work together on this project.

Activities could include (suggestions):

·        SCIENCE: Exploring simple electrical diagrams

·        MATHS: Exploring calculations (formulas) for Electricity (Volts and Ampere).

·        ACCOUNTING: Calculate the cost make the card

·        BUSINESS & ENTREPRENEURIAL STUDIES: Calculate possible and projected profits if sold to the public

·        DESIGN AND VISUAL COMMUNICATION: Planning, sketching, diagrams, and more.

·        FINE ARTS: Design and create an interesting greeting card (e.g. Happy Birthday). Explore different media (watercolours, colouring pencils, pro-markers, pastels, etc.)

·        ENGLISH: Consider words and information on back (e.g. Publishing Company, barcode, etc.)

·        DIGITAL TECHNOLOGY: Produce the results (photos, diagrams, etc.). Upload student work to school portals or internet – showcase student work.

·        ELECTRONICS: Programming Picaxe microcontrollers. Understanding simple electronic circuits and their functioning.

·       Can you think of any more subject areas that could be covered?

How to create the greetings card:

·        Research LED greeting cards. Many ideas are available on YouTube. Make notes and sketches with annotations of your ideas.

‘Cupcake Paper Circuit Card with LED Light’

Description of the project: ‘Project-Based STEM.’

WHAT IS ‘STEM’ (Science, Technology, Engineering and Mathematics)

STEM is a curriculum based on the idea of educating students in four specific disciplines — science, technology, engineering and mathematics — in an interdisciplinary and applied approach. Rather than teach the four disciplines as separate and discrete subjects, STEM integrates them into a cohesive learning paradigm based on real-world applications.

In simple terms, we are going to take a project approach in this lesson and apply Science. Technology, Engineering & Maths to learn about electricity, LED lights, batteries, making greeting cards, and more.

Explore the world of elementary science while learning how to make a light-up paper circuit card with a LED light. Practice your skills with a basic electrical circuit using conductive copper tape and a 3v battery. Use the link below to see a step-by-step illustration on how to create these LED cards.

Sparkfun:

·        Plan the ideas and concepts by making sketches and diagrams (electrical) on the card in pencil. Cardboard colour of your choice. You will be able to erase all your markings and sketches if done in pencil on the card! Don’t press too hard on the pencil when drawing and making annotations on the card!

·        Investigate a design era. In other words, you will choose a theme, which interests you. For example ‘Pop Art’

·        Remember to consult the teachers from different subject areas.

·        Consider how you will present your work. For example, taking photos of the different stages, or creating a video clip. Save the images and videos to your computer. Once completed you can consider the medium or software you are going to use to illustrate and display your work.

·        Lay the copper tape on the cardboard by removing the backing. Place the battery in position. Solder the switch and microcontroller (‘flashing function’), and an electrical switch in position. OPTIONAL: Sound (buzzer or music) components.

·        Develop a ‘backing’ (cover) for the electrical circuit. The cover is to hide the working components. Use cardboard to cover the parts (e.g. flat cardboard boxing) – paste it to the back once everything is working properly. Test the working of the card. See the accompanying image for details.

·        The card is now complete. Consider an ‘envelope’ for the card. The best option is to take a sheet of cardboard and make a flat ‘box’ for the greetings card. You could add the artwork to the front or back.

OPTIONAL: PICAXE

Depending on the age of students and/or their skill level sound could be included (buzzer/music, etc.). Consult the Electronic shop on what components are available. For experts in electronics there are so much more possibilities, like different programming components (See Picaxe). It means the student van programme a microcontroller (black chip-square shaped) by plugging in an usb cable from the microcontroller to the computer. Free software for Picaxe is available for download. For example, the student could include 3 LED lights and program the microcontroller to flash the light for 1 second and pause for 2 seconds in between flashing.

WHAT IS A PICAXE?

A PICAXE microcontroller is a Microchip PIC microcontroller that has been pre-programmed with the PICAXE bootstrap code. The bootstrap code enables the microcontroller to be reprogrammed without the need for an (expensive) conventional programmer, making the whole download system a very low-cost simple serial cable! In other words, the student can use a desktop computer and USB-cable connected to the microcontroller (Picaxe) to program the controller (to perform different functions).
