Students examine hydrothermal vents. In this ocean lesson, students identify changes in physical and chemical properties of sea water caused by hydrothermal vents.

Students investigate the dangers of radiation by exploring recent nuclear tragedies.  In this scientific debate lesson, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to...

Students distinguish safe forms of radiation from those that are dangerous. Students watch a video about sources of radiation encountered every day. Students estimate their own annual radiation exposure.

Students study photosynthesis and chemosynthesis.  For this chemosynthetic lesson students explain the processes of these and define terms. 

Students analyze hydrothermal vents. In this hydrothermal vents lesson, students discover the effects of hydrothermal vents on tectonic plates. Students make model hydrothermal vents to understand how they form and operate.

A magnitude 8.5 earthquake (such as the 1964 Good Friday earthquake in Alaska) releases about 1x1018 joules of energy. The atomic bomb exploded over Hiroshima released about 1.5x1013 joules of energy. How many Hiroshima bombs would one...
