"Glove-o-Phones" Trailer

Students discover how a vibrating balloon is like their vocal cords. They build a musical instrument that makes weird sounds when they blow into it. This relates to vibration, vocal cords, air pressure, and sound amplification. This video also includes one of Mr. Mac’s crazy stories, “Jack and Jill and BlueBeard’s Ghost,” to help students remember the lesson. Difficulty: Easy
