Pure silica sand will be unaffected by hydrogen peroxide. Salt (NaCl) will be dissolved in the H2O2-solution.
If you take sand from the garden or similar sources, the sand will have impurities (bacteria, decomposed organic matter, up to short fragments of roots) which will react with the H2O2 - large particles will be bleached, smaller ones will be oxidized and dissolved. H2O2-solution is used to free sediment samples of organic "glues" which prevent sieving. Depending on the degree of organic contamination, concentrations between 5 and 25% are used. Too strong solutions meeting lots of organic material will heat up, foam up and create a mess that can bleach skin and attack surfaces and organs (eyes, other tissue). Thinning with cold water usually slows down the foaming.

why dont you just do the experiment yourself? it would take like 5 minutes and might be kinda cool. But obviously, sand wont do anything as it is small rocks with no chemical properties.
Try the salt though, that might do something cool.
