Spacefaring bacteria in the spotlight

Students will answer questions about the online Science News article “If bacteria band together, they can survive for years in space,” which describes an experiment on the International Space Station that suggests microbes are capable of surviving interplanetary travel. A version of the story, “Bacteria can survive for years in space,” can be found in the September 26, 2020 issue of Science News.

Chemical Coaxes Locusts to Swarm

In this guide, students will learn how a newly identified pheromone may influence species behavior, research a pheromone that interests them and discuss why scientists are interested in studying such chemicals.

Chemicals cue behavior

Students will explore the chemical makeup of pheromones, how the chemicals may cue species behavior and why it’s important for scientists to study such information. Students will answer questions related to the pheromone discussed in the Science News article before applying the same questions to a pheromone of their choice.

The science of locust swarms

Students will answer questions about the online Science News article “A single molecule may entice normally solitary locusts to form massive swarms,” which describes a compound used in locust congregation that might also be used to control the pests. A version of the story, “Chemical coaxes locusts to swarm,” can be found in the September 12, 2020 issue of Science News.

Visual models for how a virus spreads

Students will analyze visual displays of data about clusters of coronavirus cases and work in groups to develop their own visual model of virus spread. Then, students will discuss how the way data are displayed affect data interpretation, and how the displays might inform public health decisions.

A Weird Solar System Cousin Makes Its Photographic Debut

In this guide, students will examine a photograph of a distant solar system, learn how astronomers captured the image and learn about the system’s inhabitants. Students will then discuss units of measure and create a scaled drawing of the distant solar system.

Capturing an exoplanet family portrait

Students will answer questions about the online Science News article “This is the first picture of a sunlike star with multiple exoplanets,” which describes a young solar system 300 light-years from our own. A version of the story, “A weird solar system cousin makes its photographic debut,” can be found in the August 29, 2020 issue of Science News.

Why use units

To determine the purpose of units in science, students will identify and compare the units used for common outer space measurements with units typically used for Earth measurements. Then, students will think about the importance of using standard units versus relative values when describing data before creating a scaled drawing of exoplanet distances.

Calculating a Dog’s Age Requires a Bit More Math

In this guide, students will learn how scientists used molecular biology to rethink a popular mathematical formula for finding a dog’s age in human years. Students will then analyze and discuss mathematical models.

Mathematical models of a dog’s age

Students will define, apply and analyze a new mathematical model for determining dog age in human years before comparing it to an old version of the model. Then, students will give examples of mathematical models in other fields and think about models’ benefits and limitations.

Old dog, new math

Students will answer questions about the online Science News article “Calculating a dog’s age in human years is harder than you think,” which explores how scientists used molecular biology to more accurately compare canine aging with human aging. A version of the story, “Calculating a dog’s age requires a bit more math,” can be found in the August 15, 2020 issue of Science News.

Starting small to curb climate change

When it comes to fighting global warming, it’s hard to know where to start. How can individuals make meaningful contributions to this effort? This activity, designed for in-class or at-home learning, encourages students to find ways they can reduce their own carbon footprints, as well as help others work toward the same goal.
