I just came across two amazing books — one brand new, and one very old — and am using them to teach how plants have moved around the globe — particularly potatoes, as that is a focus of our school garden program. Plants can be used as a frame of reference to look at global migration, and the impact that the movement of people and plants has had across the world.
This is an amazing book, looking at the history of a city and a tree, using the scope of a tree’s life as a frame of reference. Kind of puts things in perspective when you think of how long a tree lives. It would be great to use it as a way to study our own neighborhoods or cities, and as a way of studying plants and trees.
