Earth May Be Hiding Thousands of Tree Species

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.

Mapping biodiversity

Students will look at data from a primary research article to explore how tree biodiversity differs across continents and biomes.

Counting Earth’s tree species

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

The physics of flying seeds

Students will design and build models inspired by flying seeds with the goal of making the models travel as far as possible. Students will test the models, analyze which ones performed the best and explain why those models performed well using physics principles.
