Hey mate
um theres only two and one of them is not compulsory (as a prac but secondary source investigation)

so the first one is

perform a first-hand investigation to
observe the visible components of the
hydrogen spectrum

Basically
Equipment involved include: hydrogen lamp, and diffraction grating (its like a piece of glass which you look through).
Umm well its simple, you look through the hydrogen lamp then you can see various lines. Which are of course spectra lines belonging to Balmer series etc.
Also do it room with no lights (sunlight etc causes interference)

Risk analysis- dont stare directly into the light? LOL umm, handle diffraction gratings with care, dont touch the hydrogen lamp, its hot?

Yeh..the second experiment is

perform a first-hand investigation or
gather secondary information to
observe radiation emitted from a
nucleus using Wilson Cloud Chamber
or similar detection device

you can find some good explanations of this on

if you scroll down you can find my 2 cents
Hope i could help
