Data on dwindling migratory species

Students will analyze and compare two graphs to summarize a recent report about animals protected by an international treaty called the Convention on the Conservation of Migratory Species of Wild Animals before discussing the possible next steps and limitations of the treaty.

The Tiny “Toad” of Many Crowns

Scientists in Brazil have just discovered a creature that claims two small but fierce titles: the smallest known vertebrate and the smallest known amphibian. This raindrop-sized vertebrate earned a rather misleading name for itself — the “flea toad.” Use metric units to make and compare measurements and learn the differences between toads and frogs before discussing the misleading nature of the amphibian’s name.

Doggie data

Scientists in the U.K. have mapped the life spans of different dog breeds and found surprising links to body size and nose shape. In this short activity, students can explore data about their favorite dog breeds in a furry fun research study

Horned reptiles may prefer to lie in wait

Horns grant advantages to some lizard species but can be a liability to others. Learn how differences in hunting styles might contribute to physical differences in lizard species. At the same time, answer questions about evolutionary trees and convergent evolution while considering the value of analogies in helping understand complex concepts.

Designing GMO Campaigns

Humans have modified organisms for millennia through selective breeding and other techniques. But only in the past few decades have people gained the ability to directly alter organisms’ DNA to create Genetically Modified Organisms (GMOs). GMOs can help advance fields such as medicine and agriculture. In this activity, students will learn more about GMOs and their uses before creating an awareness campaign to address GMO misconceptions.

Oodles of snoozes

Every little bit of rest counts. For a chinstrap penguin, about 10,000 brief snoozes each day can add up to more than 11 hours of rest. Learn how these animals adapted to their environment by managing to grab this much-needed shut-eye. And they do it without relaxing their guard. Then answer questions discussing the relationship between habitats, behavior and sleep patterns.

Social sharing

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.

Little snake, big gulp

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.

Planning a Garden Plot

Gardens have many functions ranging from vegetable and fruit production to flood mitigation and erosion control. Gardens also can be a haven for pollinators and a repository for native plants. Over the course of a year, students will design a garden for their school or a community organization using scientific concepts they learn in class.

Fluorescing frogs

Light up your class with examples of fluorescence, including recently found biofluorescence in many frog species. Learn about the discovery of fluorescing frogs, discuss the potential evolutionary advantages of fluorescence, answer questions about the chemistry behind fluorescence and perform a demonstration of fluorescence from common objects.

A ‘Perfect Comeback’

In a “perfect comeback” move, birds may be fortifying their nests with anti-bird spikes plucked from rooftops and eaves. Learn about the new findings and foster healthy skepticism by inviting students to evaluate evidence used in the article to support claims.

Bee Geometry

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.
