This Scientist Saturday, join host Lee Hall and Dr. Denise Su, the Museum’s Chief Academic Engagement Officer, Gertrude Haskell Britton Endowed Chair of Education, and Curator of Paleobotany & Paleoecology, in a fascinating specimen spotlight. Delve into the scientific study of ancient plants and learn about specimens found in calcified lumps known as “coal balls.” You’ll discover how these lumps—consisting mostly of plant matter preserved in calcium carbonate—allow us to understand fossil plants on a cellular level. Worksheets available for grades 7-8 and 9-12.

BBC Skillswise offers many ways to help students understand adjectives. There is a factsheet, a game which involves using adjectives in an ad, three quizzes, and a worksheet. Since this is a British resource, it also provides an opportunity to note differences in British and American English. The Skillswise sites from BBC are geared to adults who are working on literacy and numeracy improvement, but are appropriate for middle school or high school students for review or remediation.

As part of the skillswise section from the BBC, this site focuses on adverbs and provides helpful tools such as a factsheet, a worksheet, and a quiz. Includes video (requires Adobe Flash).

Use this BBC Skillwise math site to learn your times tables using the different activities. Factsheets, games, three different level quizzes, and worksheets with answers available.

On April 24, 1984, the Cleveland Museum of Natural History successfully hatched its first captive-bred eaglet. The years leading up to this milestone saw declining numbers of Bald Eagles in the wild—a consequence of the use of the pesticide DDT, as well as unregulated hunting. But our efforts helped to preserve this majestic species, which is now abundant throughout the state of Ohio and beyond. In this week’s Creature Feature, learn about Bald Eagles from Harvey Webster, the Museum’s Chief Wildlife Officer & Museum Ambassador. Worksheets available for grades PreK-K and 1-2.

Programming Coordinator Nicole Episcopo gives us a behind-the-scenes look at the Cleveland Museum of Natural History’s Animal Room. She’ll highlight everything that goes into caring for our beloved animal ambassadors, as well as how our animal experts prepare them for use in classes and programs. Worksheets available for grades PreK-K and 1-2.

This printable worksheet will aid students in printing the letters of the alphabet.

If you’ve seen Bitty and Bob at the Museum, you know bobcats are incredible animals. They can leap as far as 12 feet and have a keen sense of smell. In this week’s edition of Wildlife Wednesdays, learn even more fast facts about these felines with wildlife specialist Nikki McClellan. Worksheets available for grades PreK-K and 1-2.

Have you ever seen a dinosaur graveyard? Get your chance during this week’s edition of Scientist Saturdays. Researchers estimate this event—which resulted in a mass grave of Coelophysis bauri casualties—took place about 225 million years ago, during the Late Triassic. The small dinosaurs were likely congregating around a watering hole when they perished in a freak accident (probably a monsoon, based on the evidence) and were quickly buried and preserved. Learn more about the painstaking work of Museum paleontologists to extract the fossilized Coelophysis skeletons from the block. Worksheets available for grades 7-8 and 9-12.
