Alarm bells for planet Earth

Students can search the Science News archive for the earliest stories on climate change and for techniques to combat it.

From lactose to glucose

Students will test the effect of different conditions on lactase, an enzyme that catalyzes the conversion of milk sugar to simple sugar.

Illuminating catalysts

Students will test different types of catalysts and conditions for the light-producing luminol reaction.

Catalysts 101

These discussion prompts cover the basics of chemical catalysts, enzymes as biological catalysts, the energies and physical properties of catalysts, plus related applications.

Speedy stories from the archive

Students will search the Science News archive to explore the history of catalytic material technology.

Seeking new catalysts

These questions focus on the use of catalysts in common industrial reactions and new research on alternatives to the precious metals currently used as catalysts.

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.

Probing moon formation

These questions focus on ideas about the origin of Earth's moon and evidence that supports various explanations of its formation.

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.
