Ocean noise pollution

Teacher notes

This lessons is suitable for upper KS2/KS3 and is ideally taught after one of the lessons 'How sound works'; as the main activities assume learners are familiar with the basics of the science of sound, fully covered in either of the lessons geared to KS2 or KS3. Please note: the selection of human-made and natural ocean sounds in this storyworld are powered by Hydrotwin, Portugal (specialists in marine acoustics). **National Curriculum objectives:** KS2 Science (builds on first lesson): - identify how sounds are made, associating some of them with something vibrating; - recognise that vibrations from sounds travel through a medium to the ear; - recognise that sounds get fainter as the distance from the sound source increases. Most focusses on: - recognise that environments can change and that this can sometimes pose dangers to living things - explore examples of human impact (both positive and negative) on environments, for example, MPAs - find out about and describe the basic needs of animals for survival (water, food, habitats, etc). - describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences - identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution. KS3 Science Builds on: - frequencies of sound waves, measured in hertz (Hz); echoes, reflection and absorption of sound; - that sound needs a medium to travel, the speed of sound in air, in water, in solids; - that sound is produced by vibrations of objects; - about the auditory range of humans and animals. Most focusses on: - the interdependence of organisms in an ecosystem - changes in the environment may leave individuals within a species, and some entire species, less well adapted to compete successfully and reproduce, which in turn may lead to extinction - the importance of maintaining biodiversity.
