sand and salt experiment

Last Friday we did an experiment on sand and salt, So Mr Raj added sand into a cup then put salt in the same cup. We mixed the sand and salt to together then my group added some water in the cup and mixed the water with the sand and salt, while we were mixing the thing together Mr Raj  told us to try separate the sand from the salt.

We tried separating the sand and salt from each other but we couldn’t so Mr got us to research about it, we researched and found out ways in separate the salt from the sand
