Science

A few weeks ago four people came to our school, to teach the school about science.

There names are Taiyo, kaitlyn, Nina and Juan. They come from the university of Auckland.
They made the colors of a rainbow out of different chemicals, Nina also made a fire out of two chemicals
mixed together. Kaitlyn poured dry ice into a box and but a balloon in it and when she took it out it was
deflated and when it touched the air it blow up again!!

The thing that I learnt was that there is something colder than the south pole (dry ice.).
