In this guide, students will answer questions about how scientists discovered that octopuses laying eggs in warm waters near geothermal springs are speeding up hatching. Students will then define rates and their units of measurement for biological and chemical processes and discuss factors that affect rates.
Students will answer questions about the Science News article “Some deep-sea octopuses aren’t the long-haul moms scientists thought they were,” which describes how octopuses laying eggs in warm waters near geothermal springs speed up hatching. A version of the article, “Deep-sea ‘octomoms’ seek the heat,” appears in the April 9, 2022 issue of Science News.
In this guide, students will learn about how the amount of heat energy that Earth’s upper oceans have absorbed has increased over time. Then, students will discuss strategies for interpreting, understanding and communicating data.
Students will answer questions about the online Science News article “Earth’s oceans are storing record-breaking amounts of heat,” which explores how the upper oceans’ heat storage capacity has changed over time. A version of the story, “Earth’s oceans broke heat records in 2020,” appears in the February 13, 2021 issue of Science News.
In this guide, students will learn about the extraordinary diving ability of the Cuvier’s beaked whale and what scientists think allows the marine mammal to stay underwater for extended periods. Then, students will discuss the ocean zone model and research the environment and species of a specific ocean zone.
Students will explore how the ocean environment changes with depth and how various organisms’ physical traits allow the organisms to thrive at different depths. Students then will discuss the benefits and limitations of the ocean zone model.
