In a research study about group coordination and cooperation, researchers tasked both humans and ants to solve the same sort of puzzle individually and in groups. Students will describe what they learn about the study’s experimental design, first after watching videos of the ant trials, then after watching videos of the human trials, and finally after reading a comic that summarizes the research study.

Scientists have long noted that polar bears seem to leave much of their prey behind, preferring to eat only the blubber. On first glance, this might look wasteful. But abandoned portions of that carcass might actually benefit other species in the ecosystem. Practice carrying out percentile calculations while answering questions about polar-bear predation strategies, all while discussing the ecological interplay between various species in a harsh Arctic biome.

In this lesson, students will review the human muscular system and then explore how its movements compare with those of woodpeckers. Students will also examine a diagram that shows different woodpecker muscle groups and analyze data from a research article about how those muscles are used while hammering.

Golden apple snails can completely regrow a functional eye within months of having lost one. Understanding how the snails re-create or repair their eyes might someday lead to therapies to heal people’s eye injuries or reverse some eye diseases.

In this activity, students will read the Science News Explores article “There’s life beneath the snow — but it’s at risk of melting away” and reflect on how the author of the article educates the reader. After finishing the article, students will create their own ecosystem portrait to educate their classmates about a unique ecosystem.

Freshwater fish make vast treks, but their migrations remain hidden beneath the surfaces of rivers. This invisibility has left freshwater fish largely overlooked, even as their populations worldwide have plummeted. Now, global “swimways” for migratory fish are emerging as an important conservation focus.

In this activity, students will create their own dioramas. To do this, students will observe their local ecosystem and take pictures of parts of their ecosystem that they believe tell a story. Students will then learn about how dioramas can be used to tell scientific or historical stories and will convert their ecosystem stories into 3-dimensional dioramas.

In this lesson, students will review genetics concepts, explore natural and artificial selection, and take a closer look at hybridization.

Inspired by nature’s greatest acrobats, roboticists have made engineering leaps — creating and upgrading an agile, jumping robot that can grasp branches like a squirrel. Learn how scientists use biomimicry to launch new approaches to old engineering challenges. At the same time, explore concepts of momentum in daily life, then answer questions about possible applications for squirrely robots of the future.

Some plants have evolved to produce putrid scents. Consider the phenomenon of smell before doing a card sort to show the biological and chemical processes happening in these plants. Then, answer questions about why and how the plants evolved to increase their stench.

Based on recent research, Spinosaurus is depicted swimming in the newest Jurassic World movie. Some studies point to Spinosaurus’s relatively dense bones, which could have helped control buoyancy for swimming. But others argue that Spinosaurus fossils point to its life as a wader.

Predation occurs when one organism, the predator, kills and eats another organism, its prey. In this lesson, students will learn about the recently discovered chemical predation tactics of the feather-legged lace weaver spider, which vomits toxins on its prey. Students will explore the possible evolutionary advantages and disadvantages of this technique and research another organism that uses chemical means for predation.
