When alkenes are treated with ozone and subjected to “reductive workup” with either zinc (Zn)  or dimethyl sulfide  (Me2S) [triphenylphosphine (Ph3P) also sees use], the carbon-carbon double bond is cleaved to form ketones or aldehydes, depending on the structure of the alkene.
If H2O2 is used instead of Zn (“oxidative workup”) the aldehyde will instead be oxidized to a carboxylic acid. In other words the C-H bond attached to the alkene becomes a C-OH bond. Note that ketones – which lack a C-H bond on the carbonyl carbon – are obtained regardless of whether workup is reductive or oxidative.
