Provide hands-on activities for practice and mastery. Check for understanding of concepts and skills by using relevant standard materials, i.e. worksheets, text problems, workbooks, teacher prepared exercises, etc.

Complete worksheet of sound wave diagrams. Draw a sound wave.

Objective: Students will demonstrate their knowledge of sound waves by completing a worksheet to determine amplitudes and pitches. They will also draw their "most beautiful sound" (Quadrant One) according to amplitude and pitch.

Activity: Place a copy of "Name that Sound" on the overhead. Give each student or pair of students a copy of the worksheet, "Name that Sound." Have the student complete the sheet independently or with a partner. Once students have completed the task, go over their answers. Have students then draw a sound wave of "their most beautiful sound." Have them discuss their drawing with a partner to determine accuracy of their illustrations. The instructor should move among the students to determine their understanding of how waves can be visualized. Materials: Worksheet "Name that Sound"--one per student or one per group of two students. Transparency of "Name that Sound"-1.

Assessment: Accuracy of answers on worksheet, accuracy of drawing of their "most beautiful sound." References: Sound, Workshop Leader's Guide, Operation Physics, American Institute of Physics.
