Hands-On Wednesday: Paper Airplane Launcher

Need an extra lift for your paper airplane? Then put together this paper airplane launcher! As you pull the rubber band back farther, you build up more potential energy, which transfers to more kinetic energy when you launch your plane. All you need is a wooden board, two nails, a long rubber band, a paperclip, a hole punch, tape, and of course, your paper airplane!

Hands-On Wednesday: Magnet Jar

Explore magnetic fields by making your own magnet jar! Magnetic objects can either attract or repel other magnetic objects. All magnetic objects have magnetic poles where magnetic field lines begin and end. One pole is positive and the other is negative. Try it out and see how many fun shapes you can make with the magnets!
