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

Product Information

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. 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.

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. SUPPLIESNext, 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.

optional) vellum or parchment paper, to create a diffused effect for LEDs, such as in the center of the heart in the I <3 U design 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 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. After you finish coloring the template, cut an “X” where the LED will go. The last step is to fold your template in half. Step 3 – Apply Copper Tape For more advanced students, challenge them to add more LEDs and/or sensors and buzzers to their greeting card paper circuits.Depending on the age of the students, have them especially use care with the hobby knives, which are very sharp.

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 paper circuit: A low-voltage electronic circuit created on paper using conductive copper tape, LEDs and a power source such as a small battery. In this activity, you will get to design, customize and create your own light-up card that is powered with a mini battery, an LED (or multiple LEDs), and a circuit made of copper tape. Your design is totally up to you, but templates are available if you want some ideas. (Adjust the previous sentence depending on the teacher’s planned use of the provided three templates.) Flip your template over and apply copper tape to all of the brown lines. We recommend folding the copper at the corners versus cutting it. Keeping the copper in a single continuous strip will help with its continuity ensuring the LED lights.

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 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.

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. At this point your circuit is complete. Fold the card and push the LED through the “x” you cut earlier.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. Reflection Questions: As a class discussion or a journal writing assignment, ask students the following questions: 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. 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.
