Go beyond the obvious STEM-relevant counting backwards from ten. There is a wealth of discussion points in this story, such as different weather phenomena and dangerous animals at sea. You can look into cause and venture into the world of acoustics by creating some of the sound effects from the story…

In space, no one can hear you scream

For sound to travel from one place to another, it needs something to move through. On Earth, air allows sound waves to move from one point to another. Sound can also move through water and the coat hanger is also useful for investigating how whales and dolphins communicate over such long distances. Sound waves travel through vibrations…

Hearing without ears: Dolphins

Do dolphins and whales have ears? How do earthworms hear? Why are ears shaped the way they are? Would dolphins and whales create more drag if they had external ears? Does long hair make a difference when moving through water? This STEM activity examines these questions and much more.

Children with eyes closed listening for sounds

Silence is golden

Find a cosy place to sit with the children and ask everyone to close their eyes. What can they hear? You will be surprised how many sounds the children notice when everybody is quiet. For many children, this might be the first time they consciously absorb the sounds around them…

Acoustics

There is a world of sounds out there to discover. A nice way to start any of these experiments is to lie on the floor (or on the grass outside) with your children and just listen. What can you hear? Where do the noises come from? How does the noise travel to our ears?
