 In Te Maunga this week we had a visit from the Northland Science Roadshow. We learnt about rockets, spectroscopy and water testing. For rockets I  learnt that the more air goes in the rocket the farther it will go and if you put too much water in it, it won’t so far because there is no room for the air to go. For the spectroscopy I learnt if you put a cd in a box with  a little line where you can see you can see a rainbow, it was cool. For water testing I learnt not to drink blue or green water because it has a lot of chemicals.
