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

Product Information

Every LED has a long leg and short leg. The long leg is the positive (+) and the short leg is the (-) negative. 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. 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. Insert a battery: Once all the components are installed, test the circuit by adding a battery (see Figure 4 and slide 8). Carefully slip the battery underneath the copper tape flap made earlier and center it inside the circle icon. Make sure the positive side of the battery (top, marked with the battery model and +) is facing up. Press the copper flap over the battery, and tape it down with clear tape.

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.) 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.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). 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.

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.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: 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. 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. 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.

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. 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?

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 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. 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 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

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. Reflection Questions: As a class discussion or a journal writing assignment, ask students the following questions: These DIY Light-up Christmas cards are easy and fun to make. A wonderful STEM themed Christmas activity for kids!

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