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.

These discussion prompts encourage students to discuss and compare the work and background of two SN 10 scientists to explore the varied paths to becoming a successful researcher.

This guide explores the decades-long warming trend in the Arctic and the effects that warming is already having on sea life, including phytoplankton blooms.

Students will answer questions based on the Science News article "The case of the Arctic's missing ice."

These questions explore past articles about ocean acidification in the Science News archive.

Students will discuss the scientific details that are left out of short news reports and explore how these brief reports can lead to ideas for original research.

Students will answer questions based on a series of brief news items, including describing how each demonstrates sound scientific inquiry.

These discussion prompts cover radiant energy coming to and from Earth, the effects of global warming on the land, ocean, atmosphere and on species, and possible methods of averting or adapting to climate change.

These questions focus on observations about Earth's surface temperature over time and reasons behind the changing climate.
