Scientist Nina and her young Experimenters discover the amazing ways that things can change and react in our everyday world.

Nina investigates why chocolate melts in our hands with the help of Bud and Ollie, her taste and scent neurons. Experimenters Bronte, Ruby and Sakshi visit Nina in her lab and use their senses to work out what melting is. Then Nina shows them a special metal that melts into a silvery liquid at room temperature. They find out that temperature means how hot or cold something is. Then they all go to see a hard metal called bronze being melted in a really hot furnace to make a statue. Finally, back at the lab, they do an experiment to prove that different things, like chocolate, butter and candle wax, melt at different temperatures. Show less
