Sweating has a surprising purpose for one desert plant. Students will learn about a chemical adaptation that allows the plant to collect moisture in an arid environment. They’ll answer questions about using videos to collect data and then draw molecular diagrams that illustrate the plant’s adaptation.

Working in a social group provides a variety of benefits, including the ability to learn from others and share resources. However, disadvantages can also come with working in a social group. In this activity, students will brainstorm and discuss the pros and cons of social behaviors in a variety of realistic situations. After considering how disturbances affect social behaviors, students will write a paper that evaluates the relationship between disturbances, social behaviors, and population distributions.

This little snake’s “big gulp” puts 7-Eleven to shame. Stretchy tissue in the snakes’ jaws enables them to swallow prey much wider than themselves. And the Gans’ egg-eater snake takes the cake — or egg — for most outsized meals. Learn how snakes gulp down meals much bigger than themselves while answering questions discussing proportions and comparing relative values vs. absolute measurements.

How clever! Bees use geometry tricks to make the most of their hive’s space. Learn how bees, wasps and other hive-makers accommodate changes in their colony’s needs, answer questions about evolution’s approach to problem-solving and discuss the strengths and weaknesses of analogies as literary devices.

Some scientists studying animal behavior are interested in whether nonhuman animals are intelligent and self-aware. In this activity, students will explore recent research and draw on their own experiences to consider how intelligence is defined and that definition might differ from one species to another.

Traces of one of history’s most infamous pandemics may linger in our genes. In this Guide, students will learn about a genetic link between the Black Death and a modern-day disease and discuss basic genetics concepts at the individual and population levels.

Students will read and answer questions about the online Science News article “Black Death immunity came at a cost to modern-day health.” A version of the article, “Plague immunity left a lasting mark,” appears in the November 19, 2022 issue of Science News.

Population genetics bridges the basic concepts of genes and inheritance, often studied at the individual level, with the larger concept of how a species evolves. In this discussion, students will review basic genetics concepts and investigate an example of evolution within the human population.

Ever seen a face in the moon? Or a slice of toast? What about the front of a car (and not just the characters in the movie Cars)? If so, you’re in good company. Many people see faces in commonplace objects. After learning about face pareidolia, the phenomenon of seeing faces in everyday objects, students will collect images of faces they find in nature and inanimate objects and then poll classmates on the perceived gender of the faces. Students will compare their results to results from a study reported in Science News and then design their own follow-up research on face pareidolia.

In this guide, students will answer questions about how scientists discovered that octopuses laying eggs in warm waters near geothermal springs are speeding up hatching. Students will then define rates and their units of measurement for biological and chemical processes and discuss factors that affect rates.

Students will answer questions about the Science News article “Some deep-sea octopuses aren’t the long-haul moms scientists thought they were,” which describes how octopuses laying eggs in warm waters near geothermal springs speed up hatching. A version of the article, “Deep-sea ‘octomoms’ seek the heat,” appears in the April 9, 2022 issue of Science News.

In this guide, students will answer claim, evidence and reasoning questions about how scientists used the bones of ancient fish to determine during what season an asteroid wiped out nonavian dinosaurs. They will then explore the physical properties of human bones and how bones offer evidence to support scientific claims.
