Here are the cards from my video along with the main products featured. For the full supply list, scroll down to the thumbnails at the end of this post.

NOTE: If your LED leg is too long, you can bend it along the circuit as shown below on the positive side. Step 5 – Mount The Battery Fold the card in half along the dotted center line before moving onto the next step. Tip: It is easier to make a crisp and neat fold now, before the circuit components are added to the paper. Making Light-Up Pop-Up Greeting Cards Presentation, a PowerPoint® file, to project to the class, make selected handouts or use as a teacher preparation resourceMy kids are loving this type of engineering activities lately! Do you have one that we should try next? This light-up Thanksgiving turkey circuit craft from Left Brain Craft Brain is pretty adorable! Prepare and place the LED(s): Now that the copper is in place, it is time to add the light. Each template has an LED symbol that shows a shaped wire. Using this method helps us remember which LED side is positive or negative. Share with the class the following excerpt from the light-emitting diodes tutorial about LED polarity: Set up a computer and projector to show the class the 13-slide Making Light-Up Pop-Up Greeting Cards Presentation, a PowerPoint® file. Alternatively, as makes sense for your class, just show/make handouts of certain slides for students or use the slides as a teacher preparation resource.

Depending on the age of the students, have them especially use care with the hobby knives, which are very sharp. Create copper traces: Begin the project by using copper tape to create a path for electricity. Notice that the card templates have icons to help in constructing the circuit; notice the symbols for cut, fold, copper tape, cut tape, LED, button and battery (see slide 5).

Begin with the pre-activity assessment about basic circuitry. Present the Introduction/Motivation content to the class. Then hand out the supplies and begin the presentation. Reflection Questions: As a class discussion or a journal writing assignment, ask students the following questions: Line B: Place copper tape along Line B, which includes a corner. To keep a solid connection of copper around corners, use a folding technique to press the tape into the shape (see Figure 1 and slide 6). Line up the positive (longer) LED lead with the copper tape marked + (plus) and the negative with – (minus). Use clear tape over the wire to hold it down to the copper. Electronic circuits are at the core of nearly every new technology. Circuits power cell phones, computers and televisions, and are essential in cars, houses and kitchens. Circuits are everywhere and modern innovations would not be possible without them. Circuits enable electricity to flow between speakers, bulbs, buzzers, sensors, buttons and batteries. When engineers design new technologies, they often design and build companion electronic circuits so the technology functions as intended. In this activity, students are reminded about how electronic circuits work and then build their own circuits using simple, easy-to-use materials and provided templates (three designs). A PowerPoint® presentation is provided.

electricity: The transfer of energy resulting from the flow of charged particles (such as electrons). paper circuit: A low-voltage electronic circuit created on paper using conductive copper tape, LEDs and a power source such as a small battery. For more advanced students, challenge them to add more LEDs and/or sensors and buzzers to their greeting card paper circuits.or more) LED; use the smallest size you can find so it does not add much bulk to the folded greeting card, such as 3-mm size for 35¢ each; for extra flair, consider using 3-mm, color-changing cycling RGB LEDs for 50¢ each; alternatively, cut apart individual LEDs from a set of LET string lights and then use a hobby knife to scrape the coating off the wires before using OR experiment with different LEDs to find what works best for the project objectives Have you ever wanted to give someone a Valentine’s card or a greeting card of some kind, and wanted to really impress them? Are you feel limited or bored with making the same old drawings with pencil, pen or marker? Did you know it is possible to create greeting cards that light up? Well today is your chance to make the best Valentine’s Day (or birthday, Arbor Day, holiday, etc.) card ever!

Print the template you want to use and select “Properties” in your printer settings. There should be a section to select 2-sided printing. Step 2 – Color, Cut & Fold Attach a button/switch: Next, place the LilyPad button on the oval icon on the template, facing up (see slide 10). It does not matter which side touches positive and negative. Make sure the conductive pads on the bottom of the button touch the copper tape, then tape down the ends with clear tape. Be careful not to tape directly over the push part of the button or it may interfere with the ability to press it. As an alternative, use a LilyPad switch instead of a button; the installation is the same. Prior Knowledge: In an informal discussion, quiz students about the key elements of basic circuity to see what they know about the essential circuit components and the importance of creating a continuous circuit. As necessary, refer to the diagram on slide 2 in the Making Light-Up Pop-Up Greeting Cards Presentation. Some familiarity with electronic circuits and a working knowledge of the function of LEDs, batteries and wires. If new to working with electronics, see the Additional Multimedia Support Section for suggested online resources.

The next stop in the hop is the blog of Cassie Trask!You can also start at the hop’s beginning over at the Pear Blossom Press blog. SUPPLIES electron: A subatomic particle found in all atoms and acting as the primary carrier of electricity in solids. The next step is to attach the LED to the template. Before you can do this, you need to determine which side of the LED is positive and negative. Once all wire shaping is complete, place the LED on a table or flat surface to make sure it lays flat and with the bulb upright. If not, make any adjustments now. The kids were super excited to see all the lights lit up once we had everything put together! We drew and colored a simple tree to create this fun DIY light-up Christmas card!
