This activity is based either around group work or individual depending on your needs. There is a template for the States, which can be cut out and laminated, placed in a container and then students can draw out which State they have to research. You can keep them individual, or put all of the students with the same State in a group together.
There is a PowerPoint template for the students to use as a guide to ensure that they collect all of the information needed.
This document has links to websites which are very useful for gathering information for the students.
