In this jigsaw-method activity on subduction zone volcanism, students apply lessons learned from four historic eruptions to the volcanic hazards associated with Mt. Rainier in the Pacific Northwest.

This article highlights the five essential components of cooperative learning, provides a quick overview of the research behind the strategy, describes three of the most common types, and offers ideas on how to get started using cooperative learning at the elementary level.

In the engage section of the 5Elesson, students are introduced to the role of fossils as evidence of evolution and evolutionary relationships by watching a videos about the discovery of Lucy and Ardi and consider what type of information that they can gain from skull fossils. Students will then explore features of skulls from human ancestors and the modern day Homo sapien. After measuring skull to cheekbone ratios, students will create a graph to compare various species. Several interactives are provided to explain fossils, skeletal evidence for human evolution, and phylogenetic trees. Then, students will apply their skills of analyzing data about anatomical similarities and genetic information to depict evolutionary relationships between organisms using cladograms. To evaluate student understanding, students will complete an evolutionary relationships CER.

In this jigsaw activity, students of intermediate-level French will divide into five groups to become experts on each of the five biodiversity questions featured on the Curiosphere website. They will proceed to explain their assigned aspect of the issue to a small group of students.
