what exactly is sand? like what would it do in a chemical reaction, if anything? and what does it have to do with manganese dioxide, catalase or hydrogen peroxide?

Sand is SiO2 (as mithrilhack pointed out).. regarding it's chemical proprties, well, it is acidic ie. it reacts with alkali to form silicate (SiO3 2-). It has a macromolecular stucture which means that it has a very high melting point. But why might I ask would you want to use it in connection with catalase and H2O2??? Is it some experiment about enzymes??
