Objectives

Understand how we hear sounds and begin to consider ways to reduce what we can hear.

Science Objectives
i) Identify how sounds are made, associating some of them with something vibrating.
ii) Recognise that vibrations from sounds travel through a medium to the ear.

Working Scientifically

  1. Ask relevant questions and use different types of scientific enquiries to answer them.
  2. Use straightforward scientific evidence to answer questions or to support their findings.

Lesson Planning

Teaching

  • Use what they know about the world to ask and answer questions about the hearing of humans and other animals. Understand that sound travels slower than light.

Activities

  1. Begin to understand some of the workings of the human ear.
  2. Consider some of the ways we try to reduce the sounds that we hear.
  3. Understand that we hear because sound waves (vibrations) enter our ears.
  4. Explain why we see lightning before we hear thunder.
