Wax paper (It worked much better than parchment paper.We had the best luck with a tube from ribbons and a toilet paper roll Tube-shaped objects from around the house.You can even learn to hum songs like Twinkle, Twinkle, Little Star with your membranophone. Make one with us today with the goal of making a sound in a new way. Membranophonesare really fun to make and play with. How to Make a Membranophone to Mimic a Turkey Gobble When we looked at our supplies, it became clear that we were making a DIY membranophone.Ī membranophone is a musical instrument that produces sound from a vibrating stretched membrane, like drums, gongs, or kazoo.ĭo you want to make your own membranophone? All you need is a paper roll (or other tube-shaped object), wax paper (in place of a membrane), and a rubber band (to hold it together). We needed to add a membrane to our tubes. Of course! Membrane vibration is an important part of sound production. That’s when one of my kids remembered the membrane. But nothing musical or notable.Īfter this bit of free exploration was over, I walked my kids again through the turkey sound production and asked them to think about what we might be missing. There were a lot of blowing sounds, of course, some loud huffing and puffing, a lot of laughing and snorting, and a few exasperated sighs. Well, as you can probably guess, we didn’t get much sound. What might happen when we blow air into our tubes? Will we hear a sound? What kind of sound? We often start our experiments with predictions. And when my kids peeked in their toy box, they discovered that Marble Run Track comes with lots of tube-shaped pieces. When we looked in our craft cabinet, we discovered that our ribbons were wrapped around a cardboard tube. We gathered toilet paper rolls, paper towel rolls, and drinking straws. The first step? Look for tube-shaped objects around the house. We decided that it would be fun to explore the science of that turkey gobble sound using common household items. Thanksgiving Science for Kids: Exploring That Turkey Gobble Sound In other words, this “gobble, gobble” sound is the result of a rapidly moving column of air, membrane vibration, and the air pressure inside the turkey’s vocal organ. As the air is passing through the syrinx, it increases the pressure between external and internal membranes, and we hear “ a throaty jumble of sounds that lasts 1 second.” This part of the turkey is called the syrinx. Similarly, a turkey voice is produced by air flowing through its vocal organ shaped like a tube. When a player blows into (or over) an opening at one end of the instrument, a column of air (inside the tube) vibrates, making sounds. Turkeys make noise very similarly to how wind instruments make noise. “Gobble” is only one of thirty different calls that turkeys can produce. Occasionally turkeys “gobble” when settling down for the night (akin to when you stretch on your bed at night and say “aaaah”). Watch how the turkeys interact with this expert turkey imitator: Only male turkeys (or toms) “gobble.” They mainly make the sound in spring and fall to attract a partner (or partners) and to deter other toms. But there are some facts about turkeys you might not know about. They are associated with holidays such as Thanksgiving and Christmas, and they are well-known for their large, fan-like tail, fleshy red wattles, and the famous “gobble, gobble” sound. Turkeys are one of the most famous birds in North America. How to Make a Membranophone to Mimic a Turkey Gobble.Thanksgiving Science for Kids: Exploring That Turkey Gobble Sound.
