Our class carried aout lots of experiments during science week. We made rainbow spinners so that we could see two primary colours make a new colour. We discovered that the rainbow spinners work better with a cocktail stick than a pencil. We also used some paint to make new colours.
We used diet coke and mentos to make a geyser. When we put the mentos into the diet coke it erupted. We had to do this experiment outside so that we would not make a big mess inside.
During science week we also made playdough. We made blue and pink playdough. Here is what we did:
1. Mix a tablespooon of salt, a few drops of food colouring and some water in a cup.
2. Put flour and a tablespoon of cooking oil in a bowl and mix them together.
3. Add the food colouring mixture to the flour and mix them all together until it looks like playdough.
