Oreo plate tectonics! This is such a creative way to teach students about the concept of the Earth's shifting layers. This would be a great focus activity to get students excited about learning how the movement of the Earth's plates can cause earthquakes to occur. In my unit, this would be a great way to talk about the globe and the fact that continents and oceans both have layers that move!
Trace the "Steps" to the American Revolution-- Could definitely be used for the Civil War unit or other units. One idea- assign each student an event to research. Have them copy their foot on a piece of paper and then use the feet to form a timeline.
