In this gas behavior instructional activity, high schoolers answer 5 questions about gases, how pressure, altitude and temperature effect the behavior of gases and about Gay-Lussac's Law.

Arctic sea ice reflects 80 percent of sunlight, striking it back into space; with sea ice melting, the world's oceans become warmer, which furthers global warming. These activities explore how humans are impacting ecosystems around the...

Students discuss the relationship of density to stratification. For this marine science lesson, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.

Students conduct experiments on a sample of sea water. In this oceanography lesson, students inquire how conductivity is used to approximate the salinity ocean water. Students construct their own conductivity meters and test solutions...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Learners view a tutorial on coral reefs then investigate corals under stress.  In this Earth Science lesson students prepare a written report and explain the relationship between coral reefs and their zooxanthellae.

Students research products made from petroleum. In this transportation lesson students try to find products other than fuel, made from petroleum. They look for the most unusual or surprising products and describe the history and...

Students explore the Northwestern Hawaiian Islands to discover what's there and pick up clues as to how people have both harmed and helped the native habitats. They study another protected area and see how to balance conservation efforts...

Pupils explore volume and pressure. Through an activity, students discover what happens in situations when volume is increased but no additional air is able to enter the enclosed space. Pupils create models and explain their findings....
