Teaching & Learning Sequence:

INTRODUCTION: (20 mins)

Explain to the students that they are going to go outside and they need to sit quietly and listen to the sounds around them. They need to record the sounds that they hear (writing or drawing).

Give each student a piece of paper and a pencil and take them outside. Encourage them to spread out around a large area.

Bring the class back together. Make 2 columns on the board – NATURAL and MANMADE.
Ask students to share what they heard, classifying it as either natural or manmade.

DEVELOPMENT: (20 mins)

As a class, brainstorm ‘sound’. What is it? Why do we need it? What would the world be like without sound? How would people communicate with each other?

Ask the students to put their fingers on their throat when they are talking – do they feel anything?

Give students a strip of glad-wrap/plastic and get them to hold it out tightly between their hands and blow hard across the strip – what happens? What do they feel?

Give the students the ‘Trumpet Straw’ sheet. Have them follow the instructions to make a ‘trumpet straw’. What happens? What do they feel?

CONCLUSION: (10 mins)

After doing these activities, ask the students what they can add to the brainstorm.

Ask them to consider how they “felt” sound.
