Science Investigation

In science we have been learning about solids and liquids. Here is a recount of an investigation into separating the mess. We started with a bowl of sand, salt, rice and paper clips. First we separated the paper clips with a magnet. Secondly we separated
the rice with a sieve- the rice stayed in the sieve and the sand and the salt fell through.
To separate the sand and the salt we tried to put them in the filter paper but neither of them went through. So we mixed water with the sand and salt and the dissolved salt went through the filter with the water. After that we put the salt and the water in the sun to evaporate the water, leaving the salt crystals behind.
