electron: A subatomic particle found in all atoms and acting as the primary carrier of electricity in solids. At this point your circuit is complete. Fold the card and push the LED through the “x” you cut earlier. Depending on the age of the students, have them especially use care with the hobby knives, which are very sharp. 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.)
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. SUPPLIESor 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 For more advanced students, challenge them to add more LEDs and/or sensors and buzzers to their greeting card paper circuits.
These DIY Light-up Christmas cards are easy and fun to make. A wonderful STEM themed Christmas activity for kids! 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.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. paper circuit: A low-voltage electronic circuit created on paper using conductive copper tape, LEDs and a power source such as a small battery. My kids are loving this type of engineering activities lately! Do you have one that we should try next? This light-up Thanksgiving turkey circuit craft from Left Brain Craft Brain is pretty adorable! 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.
