For Lesson 40, students worked in small groups to organize a set of 24 cards containing compounds with different shapes and functional groups. The Lesson 40 PowerPoint includes a nice graphic organizer for studying the relationship between molecule name and functional group. The Lesson 40 Worksheet and Card Sort are available for download. For homework, students are assigned questions 1, 2, and 5.
This week, students will work in groups of three students each to create a poster representing biogeochemical cycling. For the project, students will receive a worksheet with 30 different components that must be included in their poster. Students will have access to the class textbook and the class set of laptops to conduct their research. Students will also receive the Nutrient Cycling POGIL worksheet packet that will provide them with additional information about the process of carbon (C), water (H and O), nitrogen (N), and phosphorus (P) cycling. Sulfur is often included as a component of the biogeochemical cycle, frequently appreviated as the CHNOPS cycle. To help keep student projects moving forward, a variety of resources will be posted here for review.
Crash Course: Carbon and Water Cycles
Crash Course: Nitrogen and Phosphorus Cycles
Bozeman Science: Biogeochemical Cycles (includes the Sulfur Cycle)
The Global Carbon Cycle – a website with data about global carbon cycling with actual numbers that need to be added to the student posters.
Water Cycle – USGS website providing a robust review of hydrologic (water) cycle vocabulary, a presentation of the cycle itself, and data students will need to add the actual amount of water stored in various locations on Earth.
Texas A&M University has a website with pages devoted to explaining the Nitrogen Cycle. Additional in-depth information about the Nitrogen Cycle is available on the Nature Education Knowledge Project website.
Phosphorus Cycle – information about the cycle and a nice graphic from the Shmoop University website.
Sulfur Cycle – a presentation provided by North Carolina State University
Ocean acidification has become a major concern as the increasing concentration of carbon being produced has resulted in our ocean water become increasingly acidic. The movie Acid Test: The Global Challenge of Ocean Acidification is freely available online for students who would like to learn more about the consequence of our hydrocarbon-based economy on life in the oceans.
