Year 6 had a fantastic time separating mixtures and solutions this afternoon!
We had to choose the best equipment to separate:
1. Sand and cold water
2. Soil and leaves
3. Warm water and sugar/salt
We had to decide to use filtration, evaporation or a sieve. Oli, 6CD, concluded that "sieves are really good for separating different sized solids, filter paper separates liquids from solids easily, and evaporation can be used to separate solids which have dissolved in a liquid."
We also discussed the EFFICIENCY of separation methods. We decided that you could separate tea leaves from tea water by evaporation but it wouldn't be efficient - "the tea would go cold and you wouldn't be able to drink it immediately" realised Cameron. "It would be more efficient to use filter paper" he decided.
Take a look at all the super scientists in year 6!
