Learn about the horrible trials the early American settlements of Jamestown and Plymouth suffered through. Make a three part flap book about the life of Squanto. Make a model of a reed boat, like the ones floated on Lake Titicaca in Bolivia. Investigate the process that forms coal, a sedimentary rock, and make a stinky model of the process. And dress a warrior in his feathered headdress as you learn about Native American arts.
