Emphasizing the synergies between science and engineering, these video clips highlight the research of professional ocean scientists and engineers in various disciplines. The clips are accompanied by additional relevant content including images,... (View More)

In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

Sea floor spreading is demonstrated using a model consisting of two classroom desks and an 8-foot strip of paper. Changes in polarity are indicated using a felt marker. The investigation supports material presented in chapter 3, "What Heats the... (View More)

This chapter provides a series of investigations, ranging from teacher-centered to open inquiry, that involve the formation of clouds in a model cyclone, and demonstrating how the availability of heat (indicated by temperature) affects formation and... (View More)

This is a lesson about the formation of plasma bubbles in Earth's ionosphere. Plasma bubbles cause stars to twinkle and radio signals from satellites to distort. Learners will build a model ionosphere in order to demonstrate and understand this... (View More)

In this demonstration, an apple is used to help students visualize the relative amounts of land and water resources on the planet, and highlights the vulnerability of these resources we share. The apple is sectioned proportionately according to... (View More)

This is a lesson about observing and examining meteorites in a Meteorite Sample Disc. Learners will practice scientific techniques, develop skills in acquiring data through the senses, observe, examine, record, and sketch data, use magnifying... (View More)
