As long as the particles of sand and pebbles are of different size, you can separate them using a sieve (sifter). The smaller sand particles will pass through the sieve whereas the pebble molecules will not. This is the process that occurs in sifters sold as children's toys.
You would likely use a sieve and sift the material. The holes in the sieve can let the sand out while holding the stones and pebbles.
If you don't have a sieve, you can put them in a container and shake the container. The larger items end up on top and you can pick them out by hand.
with a seive or a mesh, these are graded by how many holes the have per square centimetere
You could use a wire mesh sifter, and sift the sand away from the pebbles.
The simplest method is sieving.
Use a strainer and put the sand and pebbles in the strainer (the strainers holes have to be big enough to let the sand fall through but not the pebbles,) when the sand and pebbles are in then rinse with water until sand is washed away. :)
A mixture of pebbles and water would be heterogeneous.

Water does not filter particles: it is the other way around. Pebbles, gravel, and sand are used to filter water, with the smallest particle size (sand) filtering the most particulates from the water, whether it is salt water or fresh water.
Sand and water can be separated by Filtration.
Soluble in water, sand is not.
we will separate a mixture of sand pebbles and grassgrass - winnowingsand - winnowingpebbles - handpicking .

Wash the pebbles and sand in a sieve. This will wash through the sand and keep the larger pebbles in the sieve.

I guess you could use filters.

The Sand Pebbles was created in 1962.
Sure, that's easy. First, pull out the iron filings with a magnet. Separate the pebbles by pouring the mixture through a grate, with holes large enough to allow the sand and salt to fall through, but not large enough to allow the pebbles to fall through. Finally, to separate the sand and the salt, just add water. The salt will dissolve, the sand won't. If you want to recover the salt in solid form, you can then boil away the water in the salt solution, and get your salt back. Done.
Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.

Grains of sand will move faster compared to pebbles. Sand is lighter and will easily get carried by wind, unlike pebbles, which are heavier in comparison.
it's a mixture !
