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
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.
Students will answer questions about the online Science News article “Baleen whales eat (and poop) a lot more than we realized,” which details scientists’ efforts to accurately estimate how much certain whale species eat and what that means for ecosystems. A version of the article, “Whales eat more than we thought,” appears in the December 4, 2021 issue of Science News.
Students will answer questions about the online Science News article “Here’s the physics of why ducklings swim in a row behind their mother,” which details how baby ducks save energy by surfing their mom’s waves. A version of the article, “Why baby ducks swim in a line,” appears in the November 20, 2021 issue of Science News.
In this guide, students will learn about how mitochondria help the ocean’s smallest mammal generate body heat. Then, students will discuss cell structure and energy production, diagram how mitochondria function and brainstorm a research question.
Students will answer basic questions about cell structure and energy production, draw diagrams to visualize how mitochondria in sea otters may function differently than in other marine mammals and brainstorm a research question for further investigation.
