In this activity students graph and analyze data from marine sediment cores of the coast of Santa Barbara to predict what the global climate was during the past 160,000 years.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Educator could introduce the topic with a video clip about the topic to engage students.
Not appropriate for lower middle school or students that have not been introduced to the concept of an isotope.
Teacher should reinforce the link between oxygen isotopes and climate and how scientists can use this data to determine what the climate in the past was.
Activity introduces students to the scientific method of reconstructing past climates via oxygen isotopes in marine sediment cores.
Brief data graphing activity with good questions to build the understanding of students about the complex topic of using isotope ratios to understand past climatic conditions.
Minimal pedagogic scaffolding but sufficient to carry out the activity and provide the background for the learning.
Other activities from Ocean Leadership or within CLEAN collection can complement this lesson.
Short activity with a brief set of data pulled from a scientific publication.
Detailed teacher guide includes background information and answers to the questions.
