A school project that requires your child to make an instrument from scratch can be lots of fun and educational on different levels. It teaches the basic principles of sound waves and lets kids explore the many ways that instruments create and manipulate sounds. These hands-on projects require some dexterity and artistic skills, but what entices kids most is the end result -- the chance to conjure up a wonderful cacophony, all in the name of homework.


Sticky Drum

Things You'll Need

  • Clear packing tape

  • Large coffee can, paint can, plastic bucket

Many household objects serve as de facto drums, but crafting a drum that resembles the real thing impresses your child's teacher. The basic components include clear packing tape -- which produces a loud, clear sound most like a real drum -- and an empty large coffee can, paint can or plastic bucket. Stick strips of tape over the opening, first forming a plus sign; then add strips diagonally in a star shape, all intersecting at the center. Pull the tape taut and seal the sides to eliminate gaps. Wooden knitting needles and chopsticks make excellent drumsticks.

Humming Harmonica

Things You'll Need

  • Craft sticks

  • Small rubber bands

  • Paper

  • Scissors

  • Toothpicks

Make a harmonica by sandwiching a strip of paper between two craft sticks to replicate the sound produced by a clarinet or oboe. Hold the three layers -- two craft sticks with a strip of paper cut to the same size in the middle -- by looping a rubber band around each end. Insert pieces of toothpick between the layers at each end to act as spacers and give the paper air space in which to vibrate. When you hold the harmonica up to your lips and gently blow, the paper vibrates and makes a sound. Change the pitch by squeezing the sticks together at different spots. Children can use paint, markers or washi tape to decorate the craft sticks before assembly.

Hoop Harp

Things You'll Need

  • Embroidery hoop

  • Rubber bands

Craft a very simple string instrument, similar to a harp or mandolin, using only an embroidery hoop -- plastic or wooden of any size -- and some rubber bands. A wooden hoop is easier to paint, if you want to decorate it. Stretch four or five rubber bands over the inner part of the hoop, spacing them evenly apart. The outer hoop holds the bands in place and keeps them taut. Pluck the harp as you would a guitar, holding it in one hand or placing it flat on a table. If the rubber bands snap from too much playing, they're easy to replace.

Playable Pan Pipes

Things You'll Need

  • Drinking straws

  • Scissors

  • Sticky tape

  • Ruler

  • Marker

To make a playable set of pan pipes, use drinking straws -- the larger the better -- cut into four or more pieces of successively longer lengths. Arrange the straws so that the upper edges are aligned and the bottom edges go from longest to shortest. Hold the pipes together with sticky tape. Older children can use a ruler and marker to cut the pipes to specific lengths that correspond with musical notes. For a five-note set of pan pipes that will produce the notes C, D, E, G and A, cut the straws to 6 1/16, 5 3/8, 4 3/4, 3 15/16 and 3 7/16 inches. Play both versions by blowing gently across the tops of the pipes like a flute.

DIY Xylophone

Things You'll Need

  • Picture frame

  • Metal pipes

  • Hot glue gun

  • Duct tape

A DIY xylophone consists of two parts: short metal pipes in various lengths that measure the same in diameter. Browse your hardware store's plumbing section for the pipes, and ask an employee to cut a metal pipe into sections. Find a picture frame, smaller in width than the shortest pipe is in length. Remove the glass and backing from the frame, and arrange the pipes evenly, from tallest to shortest, across the frame. Center the pipes so that all the ends extend beyond the frame. Use a dab of hot glue at the upper and lower end of each pipe to stick them to the frame. Assist younger children with the glue gun or do it for them. Stick a strip of duct tape along the center, across the front and back of the pipes and frame, for added security. Use wooden mallets to strike the pipes, or glue wooden balls to the ends of dowels for a homemade version.

Help your child better understand the way their instrument works by discussing whether it is a wind, percussion or string instrument. Talk about what "real" instrument it is most similar to.
