Lesson 1 — The Science of Sound (paired with Raven Lite)

Student Worksheet (printable)

Age: 14 • Duration: 45–60 minutes • Standards: ACSIS098, ACMMG (algebra link)

Lesson Goals

  • Observe and describe sound as a physical phenomenon using Raven Lite.
  • Use spectrograms to link visual patterns to birdsong sounds.
  • Record accurate field notes and reflect on habitat cues.

Achievement Standards

  • Explains how vibrations create sound and how frequency relates to pitch.
  • Uses Raven Lite to visualise sound and extract frequency and duration.
  • Records habitat and ethical data for citizen-science submission.

Materials

  • Raven Lite (installed on laptop)
  • Mobile audio recorder or smartphone (with permission)
  • Printed worksheet, pen, headphones

Activity Steps

  1. Gently step outside to a quiet spot, noting habitat (trees, pond, hedgerow). Write three sensory notes (sight, smell, ambient sounds).
  2. Record 30–60 seconds of birdsong (or use a sample file). Import the file into Raven Lite.
  3. View the waveform and spectrogram. Identify the most prominent call and mark its start and end.
  4. Measure peak frequency (Hz) and duration (s). Sketch the spectrogram pattern and write a short description of what the pattern suggests about the bird (fast trill, slow whistle, repeated motif).
  5. Reflect: how did the habitat notes help you predict the likely species? Would you submit this recording to a citizen‑science project? Why or why not?

Sensory Engagement & Habitat Awareness

  • Listen with closed eyes for 30 seconds before recording—note layers of sound.
  • Draw a small habitat sketch and label likely perches or water sources.

Creative Extension (Theory)

Write a short verse describing the call pattern as though it were a musical phrase. Try to clap the rhythm you see in the spectrogram.

Lesson 2 — The Mathematics Behind Sound (paired with Raven Lite)

Student Worksheet (printable)

Age: 14 • Duration: 60 minutes • Standards: ACMMG (data & algebra), ACSIS098

Lesson Goals

  • Identify and calculate amplitude, envelope, frequency and spectrum of a sound in Raven Lite.
  • Plot simple graphs of frequency vs time using measurements from Raven Lite.

Achievement Standards

  • Extracts amplitude and frequency values from audio and represents them on a graph.
  • Explains how amplitude relates to loudness and frequency to pitch using bird examples.

Materials

  • Raven Lite, laptop, sample bird audio files
  • Graph paper or spreadsheet (Excel/Google Sheets)

Activity Steps

  1. Open a recording in Raven Lite. Identify two different call types in the spectrogram.
  2. For each call, record the peak frequency (Hz) and approximate amplitude (relative units in Raven Lite).
  3. Plot frequency (y-axis) vs time (x-axis) for a 2‑second window using graph paper or a spreadsheet.
  4. Compare envelopes (how amplitude rises and falls) and describe how envelope shape affects perceived timbre.

Sensory Engagement & Habitat Awareness

  • Try to feel the rhythm by tapping a twig or your desk to match the envelope of a call.
  • Note whether calls with similar frequency come from open or dense habitats.

Creative Extension (Theory)

Convert the frequency values into musical notes (approx.) and try humming them. How musical is the bird?

Lesson 3 — Calculating Pitch (paired with Raven Lite)

Student Worksheet (printable)

Age: 14 • Duration: 60 minutes • Standards: ACMMG (algebraic manipulation), ACSIS098

Lesson Goals

  • Calculate fundamental frequency and relate it to pitch using Raven Lite measurements.
  • Explore variables that affect pitch: size of bird, call type, habitat acoustics.

Achievement Standards

  • Calculates fundamental frequency from spectrogram data and interprets biological meaning.
  • Explains how physical and ecological variables affect bird pitch.

Materials

  • Raven Lite, sample files, calculator

Activity Steps

  1. Open a recording and identify the fundamental frequency (lowest visible harmonic) of a call.
  2. If harmonics appear, note spacing between harmonics and check whether spacing equals the fundamental frequency.
  3. Use a simple formula: pitch ≈ fundamental frequency. Record values and compare across at least three species or call types.
  4. Discuss: do larger birds generally have lower fundamentals? Why might habitat (open field vs dense forest) influence the frequencies used?

Sensory Engagement & Habitat Awareness

  • Listen for echoes and note whether echoes alter perceived pitch or timbre.
  • Sketch a small forest or meadow and mark where you think the singer might have perched.

Creative Extension (Theory)

Write a short comparative paragraph imagining two birds (one small, bright-voiced; one large, low-voiced) having a conversation. Use frequency numbers to describe their voices.

Lesson 4 — Musical Ratios (paired with Raven Lite)

Student Worksheet (printable)

Age: 14 • Duration: 60 minutes • Standards: ACMMG (ratios & proportions), ACSIS098

Lesson Goals

  • Investigate ratios in sound: frequency ratios between notes and bird harmonics.
  • Relate musical intervals (e.g., octave = 2:1) to bird harmonics and call structure.

Achievement Standards

  • Simplifies and compares ratios found in spectrogram harmonic series.
  • Explains how harmonic ratios make some bird calls sound 'musical'.

Materials

  • Raven Lite, calculator, piano or keyboard (or keyboard app)

Activity Steps

  1. Identify a call with clear harmonics. Measure fundamental frequency (f1) and one or two higher harmonics (f2, f3).
  2. Calculate ratios f2:f1 and f3:f1 and express in simplest form (approximate decimal or fraction).
  3. Compare ratios to musical intervals (e.g., octave 2:1, fifth 3:2). Try to play similar intervals on a keyboard.
  4. Discuss whether the bird's harmonic structure could influence mate choice or territory signalling.

Sensory Engagement & Habitat Awareness

  • Hum the fundamental and a harmonic note together; notice beats or consonance.
  • Note if open habitats produce clearer harmonic series than dense habitats.

Creative Extension (Theory)

Compose a short 4‑beat motif inspired by a bird harmonic ratio. Write the motif down as rhythm and/or on a keyboard.

Teacher-facing Raven Lite Step-by-Step Cheat Sheet (Beatrix Potter cadence)

Below are gentle, numbered instructions for common Raven Lite tasks you will ask students to do. Where a screenshot would sit, you'll find a short description of what to expect on screen.

  1. Install & Open Raven Lite
    • Download Raven Lite from Cornell Lab and install as you might tuck a small book onto a shelf. Open the program and you will find a friendly pane ready for your sounds.
    • [Screenshot note 1: Main window with File menu at top-left; large waveform/spectrogram area central; selection toolbar above the spectrogram.]
  2. Import an Audio File
    • Choose File → Open. Select your .wav or .mp3. The recording will unfurl across the central pane like a ribbon.
    • [Screenshot note 2: File-open dialog; loaded waveform with spectrogram beneath (if enabled).]
  3. Show Spectrogram
    • If the spectrogram is not visible, toggle View → Spectrogram. The spectrogram is the coloured map of frequency across time.
    • [Screenshot note 3: Spectrogram visible, color scale at right, time axis along bottom, frequency axis up left side.]
  4. Select a Call
    • Use the Selection tool (cursor icon) to click and drag a box around the call of interest. This marks the start and end, and the top and bottom frequency of the selection.
    • [Screenshot note 4: Selection box drawn over a bright element of the spectrogram; selection info appears in a small panel or status bar.]
  5. Measure Frequency & Duration
    • Look at the selection info: it will show start time (s), end time (s), and frequency bounds (Hz). Note the peak frequency: either read from the spectrogram cursor or use spectral slice tools if available.
    • [Screenshot note 5: Status bar showing Start, End, Duration, Max Power, and frequency range.]
  6. Zoom & Refine
    • Use the magnifying glass or scroll to zoom in on time or frequency. This helps you find fundamentals and harmonics more clearly.
    • [Screenshot note 6: Zoomed-in spectrogram showing harmonic bands and the selection box refined around a single call.]
  7. Export Selection
    • To save the selection, choose File → Export Selection or use the Export button. Name the file with date_species_habitat (or 'unknown') for ease of later identification.
    • [Screenshot note 7: Export dialog; suggested filename format visible in a small note area.]
  8. Annotate & Label
    • Use annotation tools or keep a simple spreadsheet ledger: filename, date, time, GPS/place, habitat notes, observer and confidence level (high/medium/low) about species identity.
    • [Screenshot note 8: Example annotation box overlay or a spreadsheet snippet shown beside the spectrogram.]
  9. Export Data for Analysis
    • Export CSV or write down frequency and time measures for spreadsheet plotting. Students can copy frequency and time values into a graph tool to create frequency-vs-time plots.
  10. Ethics & Citizen Science
    • Remind students about ethical recording: do not play back calls to lure birds; keep a respectful distance; do not disturb nests. If submitting to citizen science (e.g., eBird), follow that platform's data guidelines.
