Hello everyone, in Te Maunga this week we had a visit from the Northland Science Roadshow. We learnt about Rockets, spectroscopy and water testing. The rockets were fun, we had one that was full of air, one filled with some water and one with fire. I learnt that how much pressure goes in the bottle the further it goes. The spectroscopy was fun, we had a box and a CD and when we looked in the small hole it wasn't really a rainbow but when we looked in the big part it was a very good rainbow. The water testing was fun, we put drops of nitrate and ammonia in the water to see what one was good to drink, the clear one was the best.
