A Spectral Mystery
It's no mystery that every gas has an emission spectrum. Scholars use a spectrograph to look at the emission spectra of nitrogen, oxygen, air, and other gases in gas discharge tubes. They use their results to determine the identity of a...

What If the Reef Dies?
Learners complete four activities to investigate how reef ecology can change. They perform experiments to show how sewage discharge can affect a marine ecosystem, look at substances that don't dissolve in water, examine wave action...

Atomic Emission Spectra and the Bohr Model of the Atom
High schoolers investigate the wavelengths of spectra lines for common atoms. For this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find...

Exploring Electricity - Four Activities
These are four classic activities used for instructing upper elementary electricians. The first involves experimenting with the Van de Graaff generator. The second is a series of hands-on experiences with static. In the third activity,...

Stellar Fingerprints: the Spectra of Stars
Students explain how an element can be identified using emission spectra. They relate the emission spectrum of hydrogen to its absorption spectrum and identify hydrogen absorption lines in the spectrum of stars.

Cnidarians
In this cnidarians learning exercise, students will read 4 descriptions and identify each as either the polyp or medusa form of cnidarian. Then students will complete 3 short answer questions about the characteristics of cnidarians....
