Holiday DIY Projects to Do at Home: Hack a Greeting Card

Want to let off a little STEAM (Science, Technology, Engineering, Art and Math) this holiday season? Then grab your family, add a few supplies and try out these fun activities! Over the next several weeks, Science Matters will feature hands-on projects that will keep kids of all ages engaged in a bit of science. Let us know which projects are your favorites and post photos of your fab results on Science Matters' Facebook page. First up - "Hack a Greeting Card" with Design Squad Nation.

Every "hacked" a greeting card? Want to learn how? Design Squad Nation, a PBS web series that features engineering projects for elementary and middle school kids shows us how to repurpose recordable greeting cards for a "FUN BUILD!" By hacking these sound making greeting cards you and your kids can build a sound system that you can hide or wear. Better yet, turn this into a customizable alarm to guard your favorite holiday cookies!  

Here's what you will need:

  • Musical greeting card. Before buying a card, ask around to see if someone has one to give you.
  • Scissors
  • Tape
  • String
  • Hiding place

Watch this Design Squad "How to" video and download the PDF for step-by-step instructions.

And now for the science in the fun: Did you know? A circuit is the path along which electricity travels. When all parts of the circuit are connected, electricity flows. A break anywhere in the circuit stops electricity flowing. In one position, the switch breaks the circuit. When that happens, the electricity stops flowing and there's no music. In the other position, the switch completes the circuit. When that happens, the electricity flows, and music blasts!

Be sure to post photos of your STEAM holiday project results on Facebook.
