Aquatic Ecosystems
An aquatic ecosystem is a community of organisms that live and interact in a water environment. There are two main types of aquatic ecosystems: freshwater and marine.
Freshwater Ecosystems
Freshwater ecosystems include lakes, ponds, rivers, and streams. They are home to a wide variety of plants and animals, such as fish, amphibians, insects, and algae. These ecosystems are impacted by factors such as water quality, temperature, and flow rate.
Marine Ecosystems
Marine ecosystems encompass oceans, coral reefs, and estuaries. They support a diverse range of life, including fish, marine mammals, sea turtles, and coral. These ecosystems are influenced by factors like salinity, temperature, and ocean currents.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
