Up With Paper Pop-Up Panoramics Light-Up Greeting Card - Holiday Lights, multi colored, 4x9 Inch (Model: A321LIT)

Product Information

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). 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: 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. 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

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.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 resource Cut a short strip of copper tape and roll it in a ball with the conductive adhesive facing out. Place this ball in the battery circle on top of the copper tape circuit. For more advanced students, challenge them to add more LEDs and/or sensors and buzzers to their greeting card paper circuits. 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).

Every LED has a long leg and short leg. The long leg is the positive (+) and the short leg is the (-) negative. Try these techniques with other pop-up designs or have students create their own. Ask students: Can you figure out how to adapt the copper tape path to fit your card choice? Further ideas and card variations:

Never connect the positive and negative terminals of a battery directly together as this causes a short circuit and the connecting material may become very hot. paper circuit: A low-voltage electronic circuit created on paper using conductive copper tape, LEDs and a power source such as a small battery.

These DIY Light-up Christmas cards are easy and fun to make. A wonderful STEM themed Christmas activity for kids!

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! electricity: The transfer of energy resulting from the flow of charged particles (such as electrons). 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. 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 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.
