In this paper, we examine a first-year torque and angular acceleration problem to address a possible use of the forelimbs of "Tyrannosaurus rex." A 1/40th-scale model (see Fig. 1) is brought to the classroom to introduce the students to the quandary: given that the forelimbs of "T. rex" were too short to reach its mouth, what…

Some of the most important scientific studies are associated with either incredibly large dimensions (e.g., the universe) or extremely small proportions (e.g., the cell). While a teacher's curriculum may often switch from mega-expanses to minutia, they should question how easily students comprehend the change in sizes. This article addresses…

The author takes a look into the benefits that dinosaurs may bring to the classroom. He discusses how he used dinosaurs as a cross-curricular theme to improve children's understanding and knowledge of science concepts. To investigate what a child might learn from dinosaurs, he started by comparing the many non-fiction dinosaur books using the…

What do paleontologists, dinosaur tracks, and the nature of science have in common? They're combined here in an inquiry activity where students use methods of observation and inference to devise evidence-based explanations for the data they collect about dinosaur tracks, much like the methods used by paleontologists. Students then debate the…

Presents activities that allow students to think about the Earth in a contextual manner and become familiar with constructive and destructive processes as they relate to sand - its origins, cyclical processes, and yielding of new products. Explores the bigger idea with a developmentally appropriate study of water, rocks, sand, physical phenomena,…

Presents a series of activities that use dinosaurs as a theme for teaching biological and geological concepts. The activities can be adapted for use with middle school through college level biology students. Exercises address such topics as: evolutionary relationships of vertebrates; Mesozoic ecology; animal tracks; and mineral replacement…
