High schoolers 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...

Students recognize the daily motion of the Sun across the sky, defining the main directions of east, west, south and north. They see how the first calendars were based on changes in the Sun's noontime elevation, and on locations of...

Students discover the underlying scientific principles in common, daily events.

Students study how fluids of differing densities interact with one another, how densities of fluids can be changed, and how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean.

Young scholars are introduced to the ecliptic, the zodiac and the apparent motions of the Sun, Moon and planets across the sky.

Students are introduced to the sundial, its design and use.

Young scholars observe the daily motions of the sun and relate them to the functions of a sundial. They determine the locations of sunrises and sunsets and determine how the elevation of the sun effects temperature.

Students are introduced to the celestial sphere, describing its apparent rotation and the special role of the pole star.

Students investigate the celestial sphere and the paths it takes in the solar system.

Young scholars receive an introduction to the sundial, its design and use.

Students examine how the link between the tilt of the Earth's axis to the ecliptic and seasons of the year--length of day, effectiveness of sunlight, polar day and night, and seasons south and north of the equator, as well as near it.

High schoolers study elevation of the Sun above the horizon and the angle of the rays and their heating power.

Learners examine how the formal definition of Newton's 3rd law: forces always originate in pairs, equal in magnitude and opposite in direction. They also examine how the informal, qualitative version: Each action has an equal and...

High schoolers learn the basic concepts about airplane flight. They learn the reason jetliner wings are swept back and why jet engines have replaced propellers in high-speed flight.

Fourth graders respond to six sayings that are introduced in this lesson. They brainstorm, justify, explain, describe, create and relate as they respond.

Ninth graders explore how Aristarchus used the position of the half-full Moon to estimate the distance to the Sun, and how he made a great error, but still figured out that the Sun is much larger than Earth.

Learners use Kepler's third law to derive the velocity in a circular orbit of any radius, and identify the Earth escape velocity.

Students participate in a P.E. tag game. They demonstrate the proper football carrying form and the hand-off position throughout the game.

Students examine how electric and magnetic fields can be used to force water out of a chamber to move a vehicle forward.

Students engage in a instructional activity to investigate the concept of all men being equal. The concept has a historical context during the time of the American Revolution. They use primary and secondary sources in order to discover...

Learners investigate the history of education for Native Americans. The roles of adults is the focus and how they delivered instruction to upcoming generations. Students focus upon the skill of oral tradition and write a summary of the...
