Hi there,
In order for you to create a notebook about rock type, you must have a note page that talks about the Rock Cycle, once you have that on the next page you must talk about the 3 main rock types (igneous, metamorphic, and sedimentary). Once you have all those main things you can now move on to identifying other rock types and determine if they are igneous, metamorphic and sedimentary. and if you want you could draw pictures or include pictures
Hope this helps :)
Have a great day
