A Whole Lot of Noise: Year 2 Explores the Science of Sound!

Recently, our Year 2 students stepped into the vibrant world of acoustics during an unforgettable Science of Sound incursion presented by Fizzics Education.

The session kicked off with students investigating a big question: what actually makes sound? Through high-energy demonstrations, the students discovered that all sounds—from high-pitched squeaks to deep rumbles—are caused by vibrations. They explored how changes in vibration speed alter the pitch, while the size of the wave determines the volume.

The highlight of the experience was seeing the invisible world of acoustic waves brought to life. Students watched digital traces move across real-time oscilloscopes and stood in awe as sand transformed into geometric patterns across a vibrating Chladni plate.

Hands-on investigation kept everyone engaged as students experimented with various acoustic tools and instruments:

• Twirl Tubes and Boomwhackers: Creating chords and testing pitch variations across different tube lengths.
• Slinky Demonstrations: Visualising how longitudinal sound waves propagate through the air.
• Thunder Drums & Music Boxes: Testing how vibrations travel through different solid materials to amplify sound.
• Foley Effects & Sonic Booms: Learning how sound effects are engineered and observing how a stock whip crack breaks the sound barrier.

By comparing predictions with their observations, Year 2 brought their physical science unit on waves and energy to life, gaining a deep, hands-on understanding of how we hear and experience sound every day.
