Homeschool State Books

One of my grown daughters favorite activities when she was being homeschooled was making state books.
Every few years or so we would study all the states. One year they had to draw and color the state and include all the main rivers, mountain ranges, national parks and cities.
On the next sheet of paper they drew, colored, and wrote about the state bird, tree, flower etc. They would also make a list of the capital, state song and any other information they might want to include.
They also had to research the state to find out why someone would want to visit that state and what they would see if they visited. Such as historical monuments, national parks, worlds biggest ball of twine etc. This would include the geography of the state as well.
We spent a half a week on each state and would spend a whole week on those that we really wanted to know more about.
We put all the states in a notebook which they now have to treasure.
