Assessment might also be discussed at this time. Try to include research, teacher-led discussions, paired and small group work, individual tasks, and some whole class activities. Play the tape with the speakers close together at first, then farther apart. If possible, change the sound to only one speaker or the other. Have students cover one ear and listen.
Investigate voice sounds.
Have them watch their faces as they say the alphabet, sing, count, etc. Provide balloons for students. Listen to the differing sounds. Speak and observe the movement as sound travels through the air. Bring into the classroom fiction and non-fiction books on Sound.
