You can't sepertate jam with raisins with a sieve because jam is lumpy so it will not fall through the sieve. But raisins are too, the holes in a sieve are to small for a raisis to fit through.
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.
The "Swimming Raisins" science project demonstrates the principles of density and buoyancy using carbonated water and raisins. When raisins are placed in the carbonated water, they initially sink due to their density. However, as carbon dioxide bubbles attach to the surface of the raisins, they become buoyant and rise to the surface. Once the bubbles pop, the raisins sink again, illustrating the cyclical nature of buoyancy in a liquid medium.
By using a filter.
The restaurant has separate areas for smokers and non- smokers.
In a beaker put in some marbles and 20ml of water.Using a filter funnel and filter paper let the water soak through the filter paper.
Using magnets or a sieve?
You can separate sand and gravel using a sieve, as the smaller sand particles will pass through the sieve while the larger gravel particles will not. You can also separate rice and beans with a sieve, as the smaller rice grains will fall through while the larger beans will be retained.
One way to separate stones from grains is by using a sieve or a mesh screen. Pour the mixture of stones and grains over the sieve and shake it gently. The grains will pass through the small holes while the stones remain on top of the sieve.
Using a sieve
You can sift flour using a sieve.
You can't it's not impossible but I can't do it you can try
A filter? Maybe a magnet (if its metal)

It is virtually impossible to separate salt and water with a sieve unless the two materials have not been touched. This is because when salt is combined with water, it dissolves, and then it is mixed in with the water. To separate these two materials, you have to let the water evaporate, so then the salt is left.
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.
One way to separate sand and hollow beads is by using a sieve or mesh. The smaller sand particles will fall through the holes in the sieve, while the larger hollow beads will be left on top. Another method is to use a process called flotation, where the density difference between the sand and hollow beads is exploited to separate them.
One common way to separate water and gravel is by using a filter. The water can be poured through the filter, leaving the gravel behind. Another method is to use a sieve or mesh to physically separate the water and gravel by pouring the mixture through it.
