This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Underneath Earth’s surface, a layer of permafrost covers 25% of the Northern Hemisphere and 20% of Earth as a whole. This continuously frozen layer contains microorganisms that remain active in subzero temperatures, but although ancient permafrost contains both dead and living microbes, typical metagenomic sequencing does not discriminate between the two. In a new study combining DNA repair protocols with high-throughput sequencing, researchers constructed a total of 52 metagenome-assembled genomes (MAGs) from ancient microbial DNA entrapped in Siberian coastal permafrost. Comparing the MAGs to those obtained without prior DNA repair protocols, they found that the MAGs from the youngest area showed minimal DNA damage. Thus, they likely came from viable, active microbes, while MAGs from older and deeper sediment appeared to be related to past aerobic microbial populations that died upon freezing. In contrast to aerobic species, anaerobic microbes such as Asgard archaea exhibited minimal DNA damage..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This activity is a field investigation where students gather data on fossiliferous limestone, develop an experimental question, and develop a mental model of local geologic history.

This article provides links to web sites about geologic time, fossils, and the archaeology and culture of the Arctic for elementary teachers.

Geysers and grizzlies and glaciers, oh my. The national parks may be America's best idea, saving the finest parts of the nation for everyone to enjoy forever. What better way to learn about the natural world than to tour the parks with us? We'll explore how the mountains and valleys formed and why they often come with volcanoes and earthquakes. You'll see what really killed the dinosaurs and how we can help save their modern relatives in the parks. With film clips, slide shows, and our geological interpretations of classic rock songs, isn't it time for a road trip?

This Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here they meet two Museum scientists who go fossil hunting every year in the Gobi, and view the duo's scrapbook. In addition to seeing photos and illustrations from the Gobi scrapbook, students learn about the journey to Mongolia, discover the challenges of fossil hunting, and see what a typical day is like for these scientists.

This activity provides an excellent example of an active debate within the scientific community regarding a relatively recent human fossil find, Homo floresiensis. The activity highlights the ways in which scientists can interpret scientific evidence in different ways, how scientists build arguments to support their claims, and how assumptions can influence interpretation. Students watch part of a NOVA program on the fossil find, and take notes on the evidence discussed. They then discuss in small groups and then as a large group which argument they consider more convincing and why.

This activity is an observational activity where students observe differnt fossils and predict what they are seeing and how old it might be.

This activity is a field investigation where students will increase their knowledge of SE MN geology including rock layers, fossils, and Karst topography. They will also learn how Karst Geology impacts our water quality.

These series of lesson are designed to help students understand the theory of plate tectonics. This content could easily be adapted to reach younger or older audiences.

The first lab activity for the course is called "Paleontology: Past, Present, and Future". In addition to discussing several documents related to present and future research directions in the field, students review a brief timeline of the historical development of paleontology as a science. Then they get their first opportunity to work directly with fossils.
Students are presented with a set of fossil specimens in boxes (with no identifying labels). Each student selects one fossil of their own. They are asked to make and record very close, detailed observations of the specimen, and to sketch the fossil. Then they are told to "think like it's 1600." Someone has brought this object, taken out of the local rocks, for the student to investigate. The student must write a "proof" that this fossil was obviously once alive, and is not just an interesting mineral or rock formation. They can use their observations, compare the specimen to other objects with which they're familiar, resort to pure logic, or apply any other avenue of argumentation they think will help make their case.

Note:
In the next lab, on fossil preservation and taphonomy, the students revisit their fossil specimen, and determine its mode of preservation. Indeed, the student's "pet fossil" could be used throughout the course to illustrate various components of the course content.

This lesson uses the fundamentals of protein synthesis as a context for investigating the closest living relative to Tyrannosaurus rex and evaluating whether or not paleontologist and dinosaur expert, Jack Horner, will be able to "create" live dinosaurs in the lab. The first objective is for students to be able to access and properly utilize the NIH's protein sequence database to perform a BLAST, using biochemical evidence to determine T rex's closest living relative. The second objective is for students to be able to explain and evaluate Jack Horner's plans for creating live dinosaurs in the lab. The main prerequisite for the lesson is a basic understanding of protein synthesis, or the flow of information in the cell from DNA to RNA during transcription and then from RNA to protein during translation

Using the Laetoli Footprints, students will explore how scientists use current patterns to understand the past. Students will answer the questions:
What do the footprints tell us?
How do scientists find that out?
Students will measure and correlate their foot lengths and body heights and use that data to estimate the height of the Laetoli hominid.

In this lesson students will learn about rock formations and fossils within rock layers. Includes video links, discussion, and activity instructions.

Learning about Antarctica's past can give K-Grade 5 teachers and students lessons in geology, climate, and ecology along with literacy experiences in sequencing and time lines. The author identifies online resources for both adults and younger learners. A three-section unit plan begins with sequencing events and follows with earth's history over billions of years and the records found in rocks and fossils. The article appears in the free, online magazine Beyond Penguins and Polar Bears.

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.

This article assembles free resources from the Learning from the Polar Past issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

This article highlights children's literature about fossils, dinosaurs, archaeology, and paleontology for use in the elementary classroom.

Three types of climate proxies -- tree rings, fossils, and ice cores -- are the subjects of lessons that will help K-5 students understand that Earth's climate has been different in the past and that scientists can reveal its history. This article is from the science lessons column of the free, online magazine Beyond Weather and the Water Cycle. The magazine is structured around the seven essential principles of climate literacy and identifies age-appropriate resources for young learners.

This activity is a combination outdoor/indoor lab where students will collect natural materials from the environment and use them to create both a mold and cast model of a fossil. Students will learn how a fossil is formed and why scientists use models to help them understand how things work and develop.
