There's not much you can do over the summer because crimebusters is lab work.
(unless you have a lab you can use?)
You can start by familiarizing yourself by reading about how to identify stuff before you actually do it.
That might save some time and effort later on.
Also, maybe try looking at some sample tests.

Speaking of having a lab to use, my parents actually bought all the chemicals and material so I could practice at home with a little lab table xD

whoa that's awesome!!!
