Question

How to separate a mixture of grass, pebbles and sand?

Answer 1

Use a considerably fine sieve ( the one used in the kitchen sometimes will do good :) ) to seperate sand from the mix of grass and pebbles. Sand will filter through the sieve while grass and pebbles stay. Now take the mix of grass and pebbles in a beaker and fill it with water.
