Treadmill-sprinting vampire bats
Learn how scientists use vampire bats' unusual locomotion to investigate mysteries of their blood-based metabolism. Then, answer questions about this study’s experimental design and discuss how chemical analysis data can support conclusions and answer scientific questions.
Immunity and polar bear pathogens
Students will learn how their bodies help protect them from bacteria, viruses and other foreign invaders. Have students review the major components of the immune system and investigate the life cycles of a few prevalent pathogens of polar bears, focusing on the mode of transmission and effects of being infected by the pathogen. Students will then infer why polar bears are being exposed to these pathogens more regularly.
How Ötzi Got His Ink
When Ötzi, the mummified iceman, was discovered in 1991, researchers thought they knew how he got his ink. But new findings cast doubt on those assumptions. Learn about unconventional approaches to tattooing and answer experimental design questions, such as the importance of sample size to a scientific study and the difference between quantitative and qualitative evidence.
A peek inside
Students will learn about the openVertebrate project and how it is digitizing vertebrate anatomy using CT scans. Then they’ll explore the archive, form a scientific question about one of the specimens and consider how to research that question.
Observing and analyzing an image
Use this short bellringer to guide students through observing details of a scientific image taken from Science News or Science News Explores articles. Students will consider the scientific process or concept behind the image. Student questions are framed around the “What I See” and “What It Means” technique.
Shining light on photosynthesis
Ever wonder how soil and seeds transform into bushes and trees? And why do these plants have specific requirements for light and water? Are there conditions that push plants to the brink? Explore such questions by taking a deep dive into the chemical processes of photosynthesis. Create a series of comics to illustrate how green plants convert light energy into stored chemical energy. Then, investigate how changes to light, water and temperature can impact plants’ ability to photosynthesize and how plants can adapt when conditions aren’t ideal.
Planning a Garden Plot
Gardens have many functions ranging from vegetable and fruit production to flood mitigation and erosion control. Gardens also can be a haven for pollinators and a repository for native plants. Over the course of a year, students will design a garden for their school or a community organization using scientific concepts they learn in class.
Counting connections in a tiny brain
Students will answer questions about the online Science News article “Scientists have mapped an insect brain in greater detail than ever before,” which explains how researchers approached finding more than 500,000 neural connections in the larval fruit fly brain. A version of the article, “The fruit fly brain in exquisite detail,” appears in the April 22, 2023 issue of Science News.
Studying the brain 101
Students will be introduced to neuroscience by learning about nerve anatomy and physiology, and they will research different methods of studying the brain.
Learning Outcomes: Develop an understanding of how scientists approach the study of the brain.
Form fits function in extreme environments
From buildings to machines to household objects — and even in the natural world — the structure of something relates to its function. Sea urchin skeletons, for example, have a recurring geometric design called a Voronoi pattern that also shows up in honeycombs and dragonfly wings. The pattern probably strengthens the skeleton and could inspire the creation of strong, lightweight materials. In this activity, students will explore aspects of structure and function in everyday objects before applying the same concepts to the natural patterns found in sea urchin skeletons. Inspired by the sea urchin, students can use an engineering design process to brainstorm solutions to real-world problems.
Making sense of animal worlds
In this activity, students will discuss how literary devices can be used to convey scientific concepts, research how an animal of their choice senses the world and compose a piece of creative writing based on what they find.
Rates and what affects them
Students will define rates and their units of measurement for biological and chemical processes before discussing factors that affect rates.
