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

Product Information

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. 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.

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. paper circuit: A low-voltage electronic circuit created on paper using conductive copper tape, LEDs and a power source such as a small battery. 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. 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 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.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: 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: 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. 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). 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

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 resourceCut 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. At this point your circuit is complete. Fold the card and push the LED through the “x” you cut earlier. Next, bend the other leg flat and curl it into a spiral by using the tip of a pliers to lightly grab the end of the wire and curl it around the tool. Depending on the age of the students, have them especially use care with the hobby knives, which are very sharp.

For more advanced students, challenge them to add more LEDs and/or sensors and buzzers to their greeting card paper circuits. 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. Reflection Questions: As a class discussion or a journal writing assignment, ask students the following questions:

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.
