Nina is back with more scientific investigations for children. She is ready to get started on a journey of discovery in her new workshop. With the help of her trusty neurons, which represent the senses (taste, touch, sight, sound and smell), Nina looks at inventions which are used in and around the home.
Each day, children join Nina in her workshop and, together, they look at items which people rely on. Nina asks where they come from, how are they made, why a bed is bouncy, how a flask works and how a vacuum cleaner sucks up dust.
As various objects are discovered, examined and taken apart, Nina and her crew get to see how they function and what makes them work, and even have a go at inventing. The neurons, as always, are called on to help out, and Nina decides which is the best one for the job.
To demonstrate how the same technology in household objects can be used on a big scale, Nina visits lots of exciting locations, including a submarine base, an observatory and the London Eye.
Today, three music-loving friends Emma, Mairi and Isabella ask Nina: How does a speaker work? In order to find out, Nina asks sound neuron, beautiful Belle, to help.
At Nina's workshop they open up a speaker and find out what's inside, before heading off to another exciting location. In this noisy episode, we'll see beads dancing to music and Nina doing a lot of shouting! But it's all in the name of science.
This episode of Nina and the Neurons Go Inventing is all about sound-waves, so tune in and discover how to invent a mini speaker of your own!
