In this ‘Sound’ unit our class will learn about how vibrations cause sounds and how sounds travel, as well as how sounds can change pitch and loudness. The children will learn about how sounds are made, carrying out demonstrations of vibrations, and completing a sound survey of their school. They will work in groups to create a human model of the way particles pass sound vibrations on, and write and star in their own documentary explaining how sound travels. The children will work in a hands-on way to explore pitch, and will use their understanding of how high and low sounds are made to create their own set of pan pipes!
In our science lesson today, we learnt how sound travels as vibrations through solids and air. To demonstrate this we made string telephones. Year 4 were amazed by how well their contraptions worked! Next, the pupils wrote an explanation of how the string telephone worked. This links with our current English topic - Explanation texts.
