Objectives |
Section 1: a. How are different sounds made?
Children should learn:
- to use appropriate language to describe different sounds
- that sounds are made as a result of vibrations
View related activities and outcomes
Section 2: b. How are different sounds made?
Children should learn:
- how to change the pitch and loudness of sounds from musical instruments
- to describe patterns in qualitative data and make generalisations from these
- to relate changes in sound to changes in vibrations
View related activities and outcomes
Section 3: c. How are different sounds made?
Children should learn:
- to use appropriate scientific language to describe features of a sound wave
- that sounds with high pitch have a high frequency
- that sounds with a high amplitude are loud
- to relate their results to scientific knowledge and understanding

Section 4: How does sound travel through solids, liquids and gases?
Children should learn:
- how the vibrations that make sound are transferred through a medium
- that sound cannot travel through a vacuum
- to relate sound travelling through a medium to the particle model
- that sound travels at different speeds in different types of material
- to use the particle model to explain how sound travels

Section 5: Checking progress
Children should learn:
- to give explanations in answer to questions

Section 6: a. How do we hear sounds?
Children should learn:
- that different people can hear different ranges of pitch
- that hearing changes with age
- that some animals detect sounds that are inaudible to human ears

Section 7: b. How do we hear sounds?
Children should learn:
- that the energy of sound is transferred through the eardrum
- that the effects of vibration to the eardrum are transferred to the brain

Section 8: c. How do we hear sounds?
Children should learn:
- how to frame a question that can be investigated
- how to decide whether measurements, qualitative observations, or data from secondary sources are appropriate
- to decide which factors in a particular investigation can be controlled
- to look critically at results and decide how strongly they show a relationship
- to compare their work with the work of others, and to evaluate it

Section 9: a. Can sound be dangerous?
Children should learn:
- how to compare loudness
- how to plan to collect data
- about reasons for repeating measurements
- to present data appropriately

Section 10: b. Can sound be dangerous?
Children should learn:
- to use their scientific understanding to interpret secondary sources on a current issue
View related activities and outcomes
Section 11: c. Can sound be dangerous?
Children should learn:
- to consider how strongly the data supports any conclusion drawn
- to consider alternative explanations
- how loud sounds can damage hearing
- to understand information that is not explicitly stated or that the reader is assumed to understand
