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

Product Information

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. These DIY Light-up Christmas cards are easy and fun to make. A wonderful STEM themed Christmas activity for kids! 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 At this point your circuit is complete. Fold the card and push the LED through the “x” you cut earlier. 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.)

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. Every LED has a long leg and short leg. The long leg is the positive (+) and the short leg is the (-) negative.

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. 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.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 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. 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. 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.

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 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. 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! Depending on the age of the students, have them especially use care with the hobby knives, which are very sharp.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.
