This informational text describes how paleontologists continue to investigate unanswered questions about dinosaurs.

In this classroom activity, middle school students examine the wide-ranging sizes of dinosaurs. The activity opens with background information for teachers about the enormous range of dinosaur sizes. In a classroom discussion, students describe the size of some dinosaurs. Then, working from an existing grid, students create either a to-scale drawing of a Tyrannosaurus head or a life-size drawing of a Protoceratops.

In this video excerpt from Dinosaur Train, Buddy and Tiny name species of dinosaurs from Apatosaurus to Zigongosaurus when they sing the "Dinosaurs A to Z" song with the help of Mr. Conductor. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

So many dinosaurs have names that come from Greek or Latin roots. This activity lets kids explore those affixes.

In this classroom activity, middle school students explore the Greek and Latin root words used to create dinosaur names. The activity opens with background information for teachers about how dinosaurs are named. As a class, students explore the Greek and Latin roots of the words photograph, terrace and other familiar terms. Working individually, students complete a worksheet that challenges them to translate the meaning of seven dinosaurs' names. Then, working in pairs, students create their own dinosaur; name it; and describe how it moves, what it eats, how it raises it young, and how it behaves.

This expository article for elementary students describes the dinosaurs that lived in polar regions as well as the adaptations that helped them survive in the dark and cold environment. Modified versions for younger grades are available.

This Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here they meet Deena Soris, who interviews the fossil of a Protoceratops. The more-than-20 questions answered by this dinosaur fossil include: You look fabulous. How old are you?How do scientists guess an extinct dinosaur's speed?Is it a thrill to have a frill?So what happened?One day you're happily munching away on thick, tough plants, the next you're history?How did you go from being a "Gobi sandwich" to becoming a fossil?Your bones were underground for 80 million years. How did the paleontologists find you?Once you got to the Museum, what happened? Are there any secrets you'd like to share with the folks at home?

This American Museum of Natural History press release, issued in April 2001, announces the discovery of a remarkably well-preserved, 130-million-year-old fossil dinosaur covered from head to tail with downy fluff and primitive feathers. The press release includes details about where the dinosaur was unearthed, and by whom, the significance of the finding, the geologic reasons why the area where this specimen was found has been a treasure trove of fossils and how dinosaurs are related to birds.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about the Fighting Dinos fossil. The site opens with a vivid account of the dinosaurs' fight. "Explore the Fighting Dinos Through a Paleontologist's Eyes" gives students an up-close look at the fossil, with notes about the clues it's given scientists. "How Did They Die, Anyway?" presents details about the three theories that have been developed about how the fighting pair was buried alive. "Bone Up Your Fossils" challenges students to match up eight dinosaur fossil photos and descriptions.

The American Museum of Natural History is home to the world's largest collection of vertebrate fossils, totaling nearly one million specimens. This Web site offers visitors a virtual visit to the Museum's famed Fossil Halls. It features seven sections along with a brief introduction, a Teacher's Guide, and information about the Museum's Division of Paleontology.

This activity is a printable one-page PDF handout, which focuses on dinosaur features. It includes an album of animal fashions in which students compare three dinosaur's frills with similar features found on animals alive today in order to determine their function and a "design your own dinosaur" challenge in which students create a dinosaur that has the features they'd like to see.

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.

In this classroom activity, young students are introduced to sets and subsets. The activity opens with background information for teachers about cladistics. After brainstorming different ways to group the class itself, students work in small groups to identify subsets of coins. The groups then complete a worksheet that challenges them to group dinosaurs into sets and subsets and share their results with the class.

In this classroom activity, young students compare their feet to the foot of a large Apatosaur. The activity opens with background information for teachers about the enormous size range of dinosaurs. After using personal references to describe the size of dinosaurs, students examine the outline of an Apatosaur footprint. Students then estimate how many of their footprints would fit inside the Apatosaur footprint and conduct an experiment to test their estimate.

This bilingual curriculum and resources guide and is designed to help elementary school teachers organize instruction to increase achievement of Hispanic primary-grade children whose first language is not English. The guide offers a curriculum plan, instructional strategies and activities, suggested teacher and student materials, and assessment procedures. Because language development is a fundamental co-requisite for learning mathematics and science concepts, processes and skills, the lessons in many instances begin with literature (e.g., stories, books) and discussion activities that set the stage for posing questions and presenting conflicting situations related to the Big Ideas in mathematics and science that are the focus of the lesson.

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

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.
