In this video segment adapted from NOVA, scientist Mike Garcia draws lava samples at the foot of the active Kilauea volcano to see if it is related to its neighboring volcano, Mauna Loa.

What can rock layers tell us about the Earth’s history? Students will be able to explain past events by analyzing rocks, rock layers, and fossils.

This article provides an overview of learning cycles and how they can enhance student learning in science.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explore how to use fossils and artifacts (scientific clues) to learn about the polar regions' past. Targeted literacy skills include making inferences, and using context clues to define new vocabulary.

Chris and Gabe Santos from the Alf Museum explain how you can learn about the Earth's history by learning how to read the rock layers at Grand Canyon National Park.

Through scientific research, this video from The Human Spark illustrates how a child’s views of what is right and wrong can be shaped by others.

This article highlights lessons and activities for elementary students about the people and cultures of the Arctic region.

This article highlights lessons and activities for elementary students about heat, insulation, and how animals and people stay warm in cold environments.

This article includes lessons that elementary teachers can use to build the foundations of climate literacy while meeting elementary science standards. Lessons are paired with literacy activities as well.

In this video segment adapted from NOVA, a team of archaeologists and engineers explores different uses of the lever by recreating the engineering feats of the ancient Easter Island peoples.

Three billion years ago single-celled underwater bacteria used sunlight to convert carbon dioxide and water into tiny oxygen bubbles. Soon plants were turning an atmosphere full of volcanic carbon dioxide into oxygen. As we learn in this video segment from Interactive NOVA: "Earth," photosynthesis created a good home for animals and humans, though not for some primitive organisms. They had to retreat to where oxygen couldn't reach them. Join researchers as they search for these organisms, now considered tiny time capsules from a time before there was oxygen on Earth.

In this video segment adapted from NOVA, scientists are startled to discover evidence for the three key ingredients for life on Saturn's moon Enceladus.

In this activity, students will explore the diverse signs of life that can be hidden in water. After reading articles and creating a news report to help them understand the significance of water on Mars, they will observe pond water under a microscope as they search for single-celled and multi-celled organisms. They will then select an organism to research more in-depth as they further consider the role that each organism plays in its ecosystem. The session will wrap up with a class discussion around whether scientists should further study the water on Mars for signs of life.

Estimated time required: 2-3 class periods.

This informational text explores Laura Gladstone's experience working at the IceCube telescope at the South Pole. She shares the clothing worn, food, what she did for fun, and how life there differs from what most of us know, including what one does NOT hear or see. The text is written at a grade two through grade three reading level. This version is a full-color PDF that can be printed, cut and folded to form a book. Each book contains color photographs and illustrations.
