This guide explores an increasingly ubiquitous technology: the smartphone. How do its sensors work, what data do they collect and how can we keep ourselves safe from its spying eyes?

In this two-part activity, students will complete a few simple light polarization exercises to model LCD technology and then demonstrate how a smartphone app analyzes and utilizes data to perform a specific function.

These discussion prompts ask students to describe how various smartphone sensors work, and analyze three graphs related to data gathered by such sensors.

This guide explores the equivalence prinicple, a foundation of Einstein's general theory of relativity, and the effects of low-gravity space environments on materials and the human body.

Students will determine if an object's composition and the height at which can object is dropped affects its gravitational acceleration.

These discussion prompts encourage students to explore concepts related to gravity and how scientists measure it.

Use this short section to explore and compare other articles about measurements of the equivalence principle as reported by Science News since 1924.

Students will answer questions based on the Science News article "Galileo experiment re-created in space."

This guide reviews the Top 10 scientific discoveries from 2017, as reported by Science News, with a focus on key concepts covered across scientific disciplines.

These discussion prompts help students gain a better understanding of key vocabulary and concepts covered in the Top 10 articles of 2017.

Students will compare and contrast one of the Top 10 stories of 2017 with an earlier related article from the Science News archive.
