Goodnight moon

Students will calculate the angular momentum and density of the moon and consider the implications of the results for various theories of the moon's origin.

Mowing down cancer cells

Working in pairs, students will analyze a graph of data from one of the cancer experiments described in "Cancer's sweet cloak."

Biomolecules from many angles

These discussion prompts cover molecular structures and properties of sugars, proteins and lipids, as well as questions related to the immune system and cancer.

Archives track a long war

Students will explore the history of cancer therapy research by searching the Science News archive.

How sugars hide cancer

These questions, based on the Science News article "Cancer's sweet cloak," highlight observations about cell-surface sugars and their ability to hide cancer cells from the immune system.

Spacetime ripples found at last

These questions focus on gravitational waves, gravitational wave detectors and how observing gravitational waves can improve our understanding of the universe.

The latest on self-driving cars

These student questions focus on autonomous vehicles and the nature of research that will support their widespread use.

Wave detection

Students will design, build, test and optmize their own light-based detector for waves (a simple optical seismometer) and will explore how this detector relates to more sophisticated gravitational wave detectors.

Wave generation

Students will generate and observe waves in a clear pan of water, drawing connections between these waves and light and gravitational waves.

Doing the wave

These discussion prompts cover the general properties and types of waves, how humans and other animals detect waves, and the design of laboratory wave detectors.

Corals across the disciplines

These discussion prompts cover coral reproduction, photosynthesis and respiration, greenhouse gases, fluorescence and how communities can minimize their impacts on reefs.

Saving the world’s coral reefs

Students will answer questions based on the Science News article "Rebuilding reefs."
