Below are links to Science Learning Hub resources related to sound in the Physical World strand of the New Zealand Curriculum. Exploring sound – resources for the early years to year 10 Explore ...
Sound is a pressure wave caused when something vibrates, making particles bump into each other and then apart. The particles vibrate back and forth in the direction that the wave travels but do ...
Sound is a pressure wave, but this wave behaves slightly differently through air as compared to water. Water is denser than air, so it takes more energy to generate a wave, but once a wave has ...
Sound waves are longitudinal or compression waves that transmit sound energy from the source of the sound to an observer. Sound waves are typically drawn as transverse waves, with the peaks and ...
Sound is a form of energy that is caused by the vibration of matter. Sound is transmitted through waves, which travel through solids, liquids and gases. We are most used to the sound travelling ...
Are you looking for ways to teach forces? If you’re new to the Science Learning Hub, you may want to start with our introductory video on teaching physics. Help, I’m teaching physics Discover ...
The video shows a hand making longitudinal and transverse waves on a slinky. The audio describes longitudinal and transverse wave characteristics.
A full-sized acoustic piano is able to play 88 distinct notes. When you press a key on the piano, a number of things happen inside the instrument. First, a damper is raised off the string ...
A standing wave is the combination of two waves that are moving in opposite directions. Standing waves are typically formed in situations where a wave is bouncing back and forth in an environment ...
This interactive shows the mechanisms of human taste. Select here to go the transcript.
Three components are needed for sound to be heard: A source – where the sound is made. A medium – something for the sound to travel through. A receiver – something to detect the sound. Source ...
Use this animated video to see 3 things needed for sound to be heard. We’re heading under water to see how the sound of a kina travels.
The ears are responsible for hearing sounds and for balance in the human body. The ear has three parts – the outer, middle and inner ears. Outer ear The outer ear collects sounds from the ...
The molecules of air are much further apart than the molecules in a liquid. A sound wave therefore travels more slowly in the loosely packed air than it does in a much more tightly packed liquid ...
In this investigation, students measure distance and time in order to calculate the speed of a sound wave. The investigation supports the science capability ‘Gather and interpret data’. It also ...
In this investigation, students work with slinkies to explore longitudinal and transverse waves. They have the opportunity to establish the relationship between frequency and wavelength and ...
If someone dropped you off several kilometres from your house, how would you know where you are and how would you find your way home? Chances are you would use visual clues – streets, buildings ...
Use music to engage students in learning the science concepts of sound in a fun and meaningful way. The New Zealand Ministry of Education’s Building Science Concepts (BSC) series presents sets of ...
When two or more sound waves occupy the same space, they affect one another. This is known as sound wave interference. Sound waves combine by simple addition. The resulting wave depends on how ...
The five sensory ‘gatekeepers’ of our bodies – taste, smell, touch, sight and hearing – help us survive. Every day, our ears, nose, tongue, eyes and skin are constantly bombarded with massive ...
This interactive explores the sequential and interlinking concepts that underpin knowledge about sound, sound waves and music.
Kina are a particular species of sea urchin endemic to New Zealand. Most of us can identify a kina shell found on a beach as a mottled green globe (sometimes intact) with a hole in the base. When ...
In this activity, students take part in a class experiment to locate sounds when blindfolded. By the end of this activity, students should be able to: design a sound location experiment and ...
In this activity, students model how sound travels by sending waves along two stretched plastic slinkies tied together. By the end of this activity, students should be able to: understand that ...
