- STEP 1: Have students stand in a circle. Toss a ball of yarn or any other soft beanbag across the circle to a student.
- STEP 2: As the ball crosses the circle, have students mimic the arc using pitch. For example if the arc is low students will begin in a low pitch, increase slightly in the middle, and end back in a low pitch.
- STEP 3: Try calling out different ways to use the voice to imitate the arc of the ball.
- Whisper
- Soft voice
- Humming
- Buzzing
- Robot
- Cat
LESSON IDEA:
This is a great way to get students to visually, aurally, and kinesthetically connect with the concept of an arc. This can be a difficult mathematic idea for students. Use this activity as a prompt for students to measure the arc of the ball and then connect it to science with the arc of frequency created by the voice.
EXTENSION:
When students are first learning this activity, stand in the center of the circle and pass the ball to individual students as they sing the arc of the ball using pitch as the ball travels through the air. Then, once students understand the concept, have them toss the ball amongst themselves while they read the arc of the ball to imitate the pitch.
