In this guide, students will learn about scientists’ efforts to estimate how many tree species Earth has, analyze a related data visualization and discuss the implications the research has for conservation.

Students will answer questions about the online Science News article “Earth may have 9,200 more tree species than previously thought,” which describes researchers’ efforts to estimate the number of tree species on Earth. A version of the article, “Earth may be hiding thousands of tree species,” appears in the March 12, 2022 issue of Science News

In this guide, students will explore chemical interactions within wildfire smoke and how urban air pollution can influence the reactions.

Students will answer questions about the online Science News article “Wildfire smoke may ramp up toxic ozone production in cities,” which explores new research into the interactions between wildfire smoke and air pollution in cities. A version of the article, “Wildfires may boost urban ozone levels,” appears in the January 15, 2022 issue of Science News.

Students will discuss the composition and properties of air and wildfire smoke, and explore how substances in smoke react to ramp up a certain type of air pollution.

Students will research how climate change affects a nonhuman species, propose science-based solutions that might lessen the impact of climate change on the species and create an infographic to share with the class.

Students will evaluate experimental methods for recycling plastics, gather data about the types of plastics they use at home, research plastics recycling in their community and write a letter to local officials that advocates for improving plastics recycling.

In this guide, students will learn about a United Nations assessment that concludes human-caused climate change is behind extreme weather events. Then, students will discuss and compare climate scenarios and visualize some of the data.

Students will learn about climate scenarios, analyze a chart of climate change impacts under four scenarios and create a data visualization for one climate change impact.

Students will answer questions about the online Science News article “The new UN climate change report shows there’s no time for denial or delay,” which describes a massive scientific assessment that concludes human-caused climate change is behind extreme weather events. A version of the story, “Earth cannot avoid a warmer future,” appears in the September 11, 2021 issue of Science News.

In this guide, students will learn about how scientists used a computer simulation to show that sea level might influence volcanic eruptions. Then, students will discuss computer simulations and brainstorm a simulation that they could use to investigate a real-world issue.

Students will discuss the purpose, benefits and challenges of using computer simulations in scientific research. Then, students will brainstorm a real-world issue that could be investigated with a computer simulation and think about how the simulation would work.
