Is it a solid? Is it a liquid?
This week in Science the children have been working scientifically using their observations to write a conclusion. Using accurate measurements, they made so called 'oobleck', using water and cornflour. After having some fun with the substance, they were making their conclusion based on the observations.
This is what we have observed:
'It is solid when I press it hard. But if I touch it gently it is more like a liquid' (Joseph)
'I think it is liquid when you don't use pressure and when you use pressure it is solid' (Zoe)
