EARTH PATTERNS, CYCLES, AND CHANGE

3.8. The student will investigate and understand basic patterns and cycles occurring in nature. Key concepts include
3.8.a) Patterns of natural events such as day and night, seasonal changes, simple phases of the moon, and tides.
3.8.b) Animal life cycles.
3.8.c) Plant life cycles.
3.9. The student will investigate and understand the water cycle and its relationship to life on Earth. Key concepts include
3.9.b) The energy from the sun drives the water cycle.
3.9.c) The water cycle involves several processes.
3.9.d) Water is essential for living things.
3.9.e) Water on Earth is limited and needs to be conserved.

EARTH RESOURCES

3.10. The student will investigate and understand that natural events and human influences can affect the survival of species. Key concepts include
3.10.a) The interdependency of plants and animals.
3.10.c) The effects of fire, flood, disease, and erosion on organisms.
