Succession is a natural pattern of change that takes place over time in a forest or other ecosystem. Students read a story about succession and investigate the connections among plants, animals, and successional stages in a local ecosystem.
Students learn about the three elements a fire needs to burn and find out how this “fire triangle” can be used to prevent and manage wildland fires, particularly in the wildland–urban interface.
Students model processes that can lead to species becoming rare or endangered. Then, they become advocates for rare or at-risk species of plants or animals and create “public relations campaigns” on behalf of these species.
Throughout history, people have intentionally and unintentionally moved plant and animal species to new environments. Some of these species have proved beneficial, but others invade natural habitats, causing environmental and sometimes economic harm.
Every living thing has a habitat—a place that meets its needs. Human beings’ habitat is the community in which they live.
Students gain an appreciation for how many natural resources they depend on in their day-to-day lives. By tracing the resources that go into making one item, students learn how its manufacturing can have an impact on the environment.
Students conduct a field study of three different environments as they focus on sunlight, soil moisture, temperature, wind, water flow, plants, and animals in each environment.
The energy we use at home, school, or work enhances our lives, but it also often contributes to air and water pollution, wildlife and habitat loss, and climate change.
The water cycle is the system by which Earth’s water is collected, purified, and distributed from the environment to living things and then returned to the environment.
Students examine trees for signs of damage or poor health and investigate conditions that may cause trees and other plants to become unhealthy.
