In this activity, students will analyze sound waves to calculate the frequency, or pitch, of musical notes.

• Identify the musical notes that make up the combination to a safe.
  
• Detect the waveform of a musical note, using a Microphone.
  
• Calculate the frequency of a musical note from the period of its waveform.

• In this data gathering activity, students will analyze sound waves to calculate the frequency, or pitch, of musical notes.
• The student pages contain complete instructions for data collection. In this lab, students must have a TI-Nspire Lab Cradle to connect the microphone. (Data collection is too rapid for the EasyLink interface)
• The student activity sheet and .tns file contain the complete instructions for data collection. All assessment questions are also included in both places giving you the flexibility to either collect the .tns files with student data/answers (using TI-Nspire Navigator) or the student activity sheet.
