Lesson 5: Wetlands

Wetlands A wetland is an area where the water level remains near or above the ground’s surface for most of the year. Examples of wetlands include marshes and swamps. Wetlands are usually found in low spots where water naturally pools and the water table is high. Most wetlands contain soils that drain slowly and retain water. Wetland

Wetland Experiment: Part 1 Scientific Question: What happens to flood water or heavy rains if they flow over a hard surface like a parking lot versus a wetland area? Make a prediction by writing or drawing pictures. Plan an experiment, and write down the steps you will follow.

Wetland Experiment: Part 1 Compare the amount of water that runs off a hard surface to the amount of water that runs off a wetland area. Record predictions, observations and other data on your “Student Scientist Sheet.”

Wetland Experiment: Part 1 Wetlands are able to absorb a large quantity of water. Wetlands only temporarily store water. The earth's water table is the upper area of the portion of the ground filled with water. If you dig into the earth, you will eventually hit water. Throughout history, many people have gotten their water by digging wells.

Wetland Experiment: Part 2 Wetlands have many different layers that help filter water as it passes through.

Wetland Experiment: Part 2 Observe the flow of water through the layers and into the glass bowl. The experiment shows that wetlands act as a natural filter. The root system of a wetland improves the quality of the water that is eventually released from the wetland. Wetlands also serve as important ecosystems and provide animals with a habitat.
