What's In The Muck? Benthic Sediment Characterization And Community Structure, Cristin Wright
Reports
Grades: 9-12 Subjects: Biology | Environmental Science | Oceanography
Sediment classification and grain size can affect the types of organisms that live in the sediment. Some organisms prefer sandier sediment, while others love the fine-grained mud.
In this activity, students will classify sediment samples by grain size and plot their findings on a ternary plot. The students will then further investigate which benthic organisms live in the different sediments and which may be more resilient to a change in sediment classification.
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.
Trawling Through The Five Gyres: A Microplastic Research Study. Subjects: Life Science, Earth Science, Marine/Ocean Science - Grade 6, Meredith Seeley
Trawling Through The Five Gyres: A Microplastic Research Study. Subjects: Life Science, Earth Science, Marine/Ocean Science - Grade 6, Meredith Seeley
Reports
This activity challenges students to help researchers understand what types of plastics are polluting the oceans!
Teachers will prepare samples of microplastics that were collected in each of the 5 ocean gyres, mimicking plastic concentrations actually found in the oceans! Working as a group, students will count the items of plastic and graph their results. They will share their results with the class to compare their gyre to the other four gyres. Finally, students will understand the link between ocean microplastic pollution, and our use of single-use plastics.
This activity can be completed in 45 minutes in the class. An …
Earthquakes, Glaciers, And Sediments, Oh My! Subjects: Earth Science, Environmental Science, Life Science/Biology Grades: 9-12, Elisabeth Clyne
Earthquakes, Glaciers, And Sediments, Oh My! Subjects: Earth Science, Environmental Science, Life Science/Biology Grades: 9-12, Elisabeth Clyne
Reports
This lesson plan is developed for 9th grade earth science classrooms, but can be scaled up or down. Students will explore how marine sediments serve as a history book for geologic activity. They will collect mock cores and developing conclusions about earth history.
