Primary 4 will be learning about the different ways of producing sound from vibrations and how to change the pitch of sound in Science this term.

For homework for this unit, Primary 4 can make some musical instruments, where the pitch of the sounds can be altered. This could include elastic band guitars, drums or panpipes.

They could also research in books or online to find out about other animals that produce infrasound, such as whales, alligators or Rhinoceros.

They could make a string telephone by connecting two empty cartons with a long piece of string and try them out to see if the string can carry the vibrations from their voice to someone in another room.

They will also be moving on to learn about the human skeleton and its purpose. For homework on this subject, pupils can research the skeletons of some animals of their choice. They can make drawings and label them and bring them into school to compare with human skeletons.
