Physicists propose that trees may help detect high-energy subatomic particles called neutrinos. Learn how Earth’s atmosphere alters these incoming high-energy subatomic particles from space. Then, explore how scientists could use this interplay to develop new ways to detect high-energy neutrinos.

The sound of running water can evoke thirst or make for a relaxing environment. Physicists have recently figured out what causes the burbling of this alluring sound. Get your students thinking critically about this everyday phenomenon and explore possible variables behind it. Then have them read about a recent scientific study that explains the physical science principles behind the burbling water.

Students will discuss the physics of drag using real-world examples.

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.

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.

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.

In this activity, students will analyze infrared images and then explore how infrared imaging is used across a range of fields of work. Skills include researching, evaluating, synthesizing and presenting information.

Students will watch a NASA video about the electromagnetic spectrum to learn about properties of the various types of radiation. Then, students will explore and discuss technologies that use specific types of electromagnetic radiation.

Students will answer questions about the Science News article “Coating provides infrared camouflage,” which explores the physics and potential technological applications of a material.

Students will use decibel meters to understand how the volume of a sound changes as it travels away from a source. Concepts covered include sound waves, the inverse square law, absorption and reflection. The activity also asks students to consider how the characteristics of a space affect the sound.

Drawing on their experiences with how sound behaves in different spaces, students will explore the engineering process by designing and sketching a room to meet specific sound requirements.

Students will answer questions about the Science News article “Saving Notre Dame’s sound,” which explores how scientists resurrect acoustics of historic places.
