Learn, Protect and Promote Water!: In this lesson students learn about water sources, water pollution, and water protection. Students participate in an activity where they demonstrate the water cycle and see the potential for our water supply to become contaminated.
Overfishing and Aquaculture: Students will discover the sources of various fish and seafood, compare wild-caught and farm-raised aquaculture systems, and use a simulation to learn how overfishing can damage the ocean ecosystem.
Properties of Soils: Students examine the components of different soils and recognize how sand, silt, and clay particles effect air space and water absorption.
The Environmental Cost of Food: Students examine the environmental footprint of food by discovering factors along the farm-to-fork process that contribute to a food's environmental footprint and discuss possible solutions to create a sustainable future through the foods we eat.
The Remarkable Ruminant: In this lesson, students will follow the farm to fork process of producing beef, learn how cattle and other ruminants convert grass into nutrient-rich foods such as milk and meat, discover ways cattle recycle food waste, and identify careers in the beef cattle industry.
Watersheds, Soil Profiles and Erosion: Students develop an understanding of what factors impact water quality within watersheds, what soil types/profiles are most susceptible to erosion, what factors impact water quality within watersheds, and how to mitigate erosion on susceptible soils.
Water Quality: Students investigate the effects of added soil nutrients on water quality, perform chemical and physical tests on water samples, collect and identify macro invertebrates from a freshwater system and compare physical, chemical and biological factors of an aquatic ecosystem to determine water health.
