The Distribution of Earth's Resources
At Yasuni National Park, forests can be so dense they are difficult to walk through. But at Big Bend National Park, there are vast open stretches of dry land.
Students build an initial model of this integrated phenomenon at the start of the segment and revise it after each unit. Use the chapter phenomenon pages to feed that model.

Processes that Shape Earth
Earth's natural resources, like minerals, energy, and groundwater, are unevenly distributed across communities.
- 16 Earth's Tectonic Plates
What evidence convinced scientists that the continents move, and how did that evidence turn a hypothesis into the theory of plate tectonics?
1 presentation10 worksheets3 labs - 17 The Rock Cycle
How does the rock cycle model the ways Earth's materials move and change, and where does the energy for each change come from?
1 presentation10 worksheets3 labs - 18 The Water Cycle
What moves Earth's water from place to place, what makes it change between solid, liquid and gas, and why can the same water end up in so many different places?
1 presentation10 worksheets3 labs - 19 Earth's Natural Resources
Why are mineral, energy and groundwater resources concentrated in some places and missing from others, and what happens to that pattern as people use them?

Resources in Ecosystems
When various species of cichlid fish are combined in aquariums, some stop eating to the point of dying.
- 20 Resources in Living Systems
What do living things need from their surroundings, and what happens to organisms and populations when a needed resource runs short?
1 presentation10 worksheets3 labs - 21 Interactions Among Organisms
Why do the same kinds of relationships between species appear in ecosystems that share no species at all, and how can knowing those patterns let us predict what happens when one population changes?
1 presentation10 worksheets3 labs - 22 Changing Ecosystems
How do ecosystems change over time, and how can we use evidence to argue that a change to one part of an ecosystem affects the populations living there?

States of Matter
Ice eventually turns into water when it is left out, and water boils and seems to disappear when it is heated.
- 23 The Motion of Particles
How does the motion of particles explain what a solid, a liquid and a gas can do, and what happens to that motion when thermal energy is added or removed?
1 presentation10 worksheets3 labs - 24 Heat, Temperature, and State Changes
When thermal energy is added to or removed from a substance, what happens to how its particles move, to its temperature and to its state?
