Science - Sound - How the ear works

For our lesson on sound this week we will...

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

Use the attached powerpoint, BBC Bitesize webpage and attached activities  resource to further the childrens knowledge on the hearing of humans and other animals. Understand that sound travels slower than light.

2. Consider some of the ways ears are adapted using the animal ears tasks.
3. Try the British sign language spelling activity.
4. Cone ears! Make predictions and test them by making cone ears to improve or reduce your hearing.
