Sound Experiment

Level 4

Pupils understand the need for care in framing questions when collecting, finding and interrogating information. They interpret their findings, question plausibility and recognise that poor-quality information leads to unreliable results. They add to, amend and combine different forms of information from a variety of sources. They use ICT to present information in different forms and show they are aware of the intended audience and the need for quality in their presentations. They exchange information and ideas with others in a variety of ways, including using e-mail. They use ICT systems to control events in a predetermined manner and to sense physical data. They use ICT -based models and simulations to explore patterns and relationships, and make predictions about the consequences of their decisions. They compare their use of ICT with other methods and with its use outside school.

Next steps: The children are using data logging for a clear purpose; to investigate what happens to sound as it travels through a tube. They copied and pasted their graph into a Word template in order to write about it. The children need to draw more detailed conclusions and think how they could apply what they have discovered (i.e. what difference does the tube make and why e.g. As predicted, the tube stopped the sound waves spreading out. We know the sound energy travelled down the tube because the sound level two metres from the speaker, was 10 decibels lower when we tested without it. The tube must have absorbed some of the sound energy though, as the reading with the tube was still lower than the sound level recorded next to the speaker.)
