Teaching Natural And Artificial Selection In Production Agriculture, Madhav P. Nepal, Clayton W. Scott
Teaching Natural And Artificial Selection In Production Agriculture, Madhav P. Nepal, Clayton W. Scott
iLEARN Teaching Resources
In this lesson, students will learn how natural selection and artificial selection impact both production agriculture and biological sciences. A natural selection is a mechanism that favors heritable traits that increase species survival and reproduction. Artificial selection is a selective breeding, where humans select for desirable traits in agricultural products.
Sequence Csi: The Nitrogen Cycle. Subjects: Life Science, Environmental Science, Marine/Ocean Science - Grades: 9-12, Stephanie Wilson
Sequence Csi: The Nitrogen Cycle. Subjects: Life Science, Environmental Science, Marine/Ocean Science - Grades: 9-12, Stephanie Wilson
Reports
This lesson invites students to work together to identify a mystery DNA sample using state of the art biotechnology.
After identifying the organism, they can work with another group of students to hypothesize about how the different organisms are related to one another. Students will learn that the samples are connected through the nitrogen cycle! This gives students an introduction to scientific molecular techniques and environmental nitrogen cycling.
Expedition Sediments: Mud's Journey Through The Watershed. Subjects: Earth Science / Environmental Science Grades: 9-12, Jessie Turner
Expedition Sediments: Mud's Journey Through The Watershed. Subjects: Earth Science / Environmental Science Grades: 9-12, Jessie Turner
Reports
Expedition Sediments is a game-in-a-lesson that allows students to explore the movement of sediments through watersheds by moving around the classroom. This lesson explores how grains of estuarine mud and sand move throughout estuaries and coastal regions, with a focus on processes surrounding a highly populated estuary such as the Chesapeake Bay. By the end of the lesson, students will be able to explain how sediments are transported through an estuary, graph sediment residence times in different locations, and compare the timescales of different sediment transport processes.
One Fish, Two Fish, Red Fish, Whose Fish? Subjects: Life Science, Environmental Science, Marine / Ocean Science, Shelby White
One Fish, Two Fish, Red Fish, Whose Fish? Subjects: Life Science, Environmental Science, Marine / Ocean Science, Shelby White
Reports
This activity invites students to assume the role of various stakeholders in fisheries management and actively discuss the influence of economics, ecology and human interactions in decision-making.
Students will demonstrate their argument for/against a certain regulation by participating as a specific stakeholder (i.e. commercial fisher, recreational fisher, scientists/researcher, environmental group, management agency, and citizen). Students will recognize that stakeholders tend to advocate based on their individual needs, often making it difficult for proposed policies to satisfy the needs of all stakeholders and achieve sustainability goals.
Microscopic Hitchhiking: Taking A Trip With Microbes And Plankton. Subjects: Life Science / Biology, Environmental Science, Marine / Ocean Science Grades: 6-8, Lucia Safi
Reports
This lesson plan develops concepts on food webs and ecological relationships, giving special attention to microorganisms and Chesapeake Bay species and dynamics. Students will conduct investigations, generate their own data and find out more about species they constantly see!
Counting Blue Crabs In The Bay! Subjects: Life Science / Biology, Environmental Science, Marine / Ocean Science Grade Level: 6-8, Bruce W. Pfirrmann
Counting Blue Crabs In The Bay! Subjects: Life Science / Biology, Environmental Science, Marine / Ocean Science Grade Level: 6-8, Bruce W. Pfirrmann
Reports
This lesson plan invites students and teachers to ponder the question: How many blue crabs are in the Chesapeake Bay, and where do we find them? Through hands-on activities and the use of real data, students will discover the excitement and grapple with the challenges faced by marine scientists as they try to quantify the use of different habitats by marine animals and estimate the size of marine animal populations.
Marine Parasites And Fish: How To Sample And Analyze. Subjects: Life Science / Biology, Environmental Science, Marine / Ocean Science Grades: 6-8, Zoemma Warshafsky
Marine Parasites And Fish: How To Sample And Analyze. Subjects: Life Science / Biology, Environmental Science, Marine / Ocean Science Grades: 6-8, Zoemma Warshafsky
Reports
This lesson plan provides a hands-on way for students to investigate the impacts of an invasive parasitic nematode which has been targeting the American eel. Students will first “infect” pipe cleaner eels with parasitic nematodes (beads), which will then be used to simulate real-life research efforts through collecting multiple random samples of “eels” and counting the amount of parasites. They will then use this data to calculate prevalence, mean intensity, and mean abundance.
Digesting Data - Subjects: Life Science / Biology Grade Level: 6-8, Amanda Bromilow
Digesting Data - Subjects: Life Science / Biology Grade Level: 6-8, Amanda Bromilow
Reports
This lesson plan encourages students to become scientific investigators to determine which fish species are important predators of juvenile blue crabs in Chesapeake Bay. Students will have the opportunity to practice using triple-beam balances and draw conclusions based on their data.
