Renee Clary and James Wandersee implemented the Stratigraphy and Data Interpretation Project described in this article when they recognized that some students were having difficulties constructing appropriate graphics and interpreting their constructed graphics for an earlier mathematics-science project in their classrooms. They also previously…

Stromatolites are the rocklike structures produced by "microbial mats"--communities of microorganisms only a few millimeters thick--as they trap, bind, or precipitate minerals. This article provides activities and assessment ideas to help teachers incorporate stromatolites in their classrooms. It relates the study of stromatolites to the…

Gravel is a component of parking lots, highway shoulders, garden pathways, and filtration systems. Few people bother to scientifically examine gravel and determine its origin, but gravel can be an effective, inexpensive, and abundant resource for science classrooms. It can serve as a portal for several interdisciplinary science activities and…

This article discusses a creative visualization project to motivate and engage students. Students depict a dinosaur in its ecosystem and include all three elements of the environment: air, land, and water. Students explore scientific content in evolution, natural selection, food webs, ecosystems and geologic time. (Contains 6 figures.)

Dinosaurs in the middle school classroom can be exciting. These extinct reptiles are both an exotic subject and familiar to our students. Because students are inherently interested, dinosaurs can serve as an effective portal for the integration of biology, geology, ecology, and the history and nature of science. The field of dinosaur study is…

Earthquakes "have" been in the news of late--from the disastrous 2010 Haitian temblor that killed more than 300,000 people to the March 2011 earthquake and devastating tsunami in Honshu, Japan, to the unexpected August 2011 earthquake in Mineral, Virginia, felt from Alabama to Maine and as far west as Illinois. As expected, these events…

Coal fueled the Industrial Revolution and, as a result, changed the course of human history. However, the geologic history of coal is much, much longer than that which is recorded by humans. In your classroom, the coal cycle can be used to trace the formation of this important economic resource from its plant origins, through its lithification, or…

Through integration of geology, biology, chemistry, and the history of science, the historic Krakatoa eruption offers a unique portal for student inquiry in the classroom. Students are inherently fascinated by natural disasters, and modern comparisons to the Krakatoa cataclysm are as close as the day's news. This article uses the historic Krakatoa…

Professors of an online graduate-level paleontology class developed the concept of marquee fossils--fossils that have one or more unique characteristics that capture the attention and direct observation of students. In the classroom, Marquee fossils integrate the geology, biology, and environmental science involved in the study of fossilized…
