Ei E: A Stick in the Mud: Evaluating a Landscape Lesson 4 Part 1

Who is not drawn to trading cards? In this lesson, junior ecologists create a trading card of an animal or plant from one of Arizona's biotic communities. Gorgeous sample cards are provided in the lesson plan as well as a plethora of...

Compare the volume of an orange to the volume of liquid that can be extracted out of it. Also compare the mass of an apple before and after it has been dried out. In both of these activities, children find that there is an appreciable...

Students use maps to study the erosion along a riverbank over time and conduct controlled experiments to determine how soil compaction around a foundation affects the foundation's strength. [7:20]
