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.

Beets Bleed Red, But Chemists Turn It Blue

In this guide, students will learn how light and chemical structures affect color and how chemists apply that knowledge to create pigments. Students will then pair up to research a pigment of their choice.

Creating the blues with chemistry

Students will answer questions about the online Science News article “Beets bleed red but a chemistry tweak can create a blue hue,” which explores how scientists altered the molecular structure of a pigment molecule from beets. A version of the story, “Beets bleed red, but chemists turn it blue,” can be found in the May 9 & May 23, 2020 issue of Science News.

Colorful chemistry

Students will review concepts of light and chemical structures to explore color. Then, students will partner up to research a pigment of their choice and present their findings to the class.

Where Bacteria Live On Our Tongues

In this guide, students will learn about bacterial communities on the human tongue and use existing knowledge of interspecific interactions to create metaphors about relationships in the students’ own communities. In an activity, students will practice note-taking and summarizing skills.
