Fifth graders study the components and function of the nervous system. They investigate how engineers design biomedical equipment to assist the nervous system and explain how the five senses are affected during spaceflight.

Students observe and explore the characteristics of light.

High schoolers discuss how the horizontal transport of heat from equatorial regions polewards drives global wind systems.

Students discuss the way vertical convection transports heat from the surface upwards, and associated pressure and temperature profiles of the atmosphere.

High schoolers distinguish between the centripetal and centrifugal forces.

Young scholars participate in a qualitative discussion of the distinction between weight and mass, followed by a description of astronaut mass measurements in a zero-g environment.

Young scholars study the heliocentric theory of Copernicus, the ideas behind it and the explanations which it displaced. A discussion of retrograde motion of planets helps students explain the logic underlying the ideas of both Ptolemy...

High schoolers examine the observation of "coronal holes," by x-rays, also about related fast streams and moderate magnetic storms that recur at 27 day intervals. They study NASA'S great observatories.

Students explore magnetism and magnetic phenomena on the Sun.

Students discuss the solar heating of the Earth and atmosphere, its heat loss proceses, and the way these relate to weather and climate.

Students explore rotating frames of reference, focusing on the weightless environment in space and the Coriolis force.

Students discuss the application of frames of reference to an airplane flying with a constant velocity v through the air.

High schoolers study about deriving centripetal acceleration for motion at constant speed around a circle.

Learners trace the beginning of the heliocentric theory of the solar system--the idea that the solar system revolves around the Sun--to an observation by the Greek astronomer Aristarchus, which convinced him that the Sun was much bigger...

Learners explain how Hipparchus, around 130 BC, used a shift in the predicted location of a lunar eclipse to detect a slight shift in the path of the Sun around the sky. They examine the elliptical orbit in which the Earth travels around...
