This clip is useful as a discussion tool - children could answer questions about the clip such as "What are the devices that use technology used for? What do you think the animals can hear?". This could lead on to learning about how sound travels and investigate vibration using a range of instruments. This could be demonstrated by the teacher by knocking stones together over a candle. String and cups could be linked to show sound travelling. The children could make different length string cup phones and see what difference it makes.
