How ducklings dodge drag

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

Quacking the physics of duckling swimming

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.

Creating the blues with chemistry

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.

Colorful chemistry

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.

Seeing in infrared

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.

Exploring electromagnetic radiation

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.

Hiding heat 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.

A world of acoustics

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.

Designing soundscapes

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.

Sound science at Notre Dame

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