Title: Photosynthesis, Trees, and the Greenhouse Effect
In this lesson, from Xpeditions, students study photosynthesis and then then transfer their understanding of this topic to a consideration of how trees can help reduce the negative impacts of the greenhouse effect. They read a Web page describing the greenhouse effect, carbon dioxide's role as a greenhouse gas, and the role of humans in exacerbating this effect. Students also browse the Web site of an organization that sponsors tree planting programs and consider how these programs might help reduce or slow down the increase of the greenhouse effect. They conclude by writing paragraphs telling younger kids about the benefits of trees and plants.
Standard(s): [S1] BOT (9-12) 7: Explain plant cell processes, including light dependent and light independent reactions of photosynthesis, glycolysis, aerobic and anaerobic respiration, and transport.
Title: Weather and Agriculture
In this Xpeditions lesson, students research, discuss, and write reports on the relationship between climate and agriculture. They pretend that they've just purchased farms in specific parts of the United States and investigate that region's weather and climate in order to maximize the chances that their farms succeed.
Standard(s): [S1] GEL (9-12) 9: Describe the movement and storage of water in terms of watersheds, rainfall, surface runoff, aquifers, and surface water reservoirs.
