Eratosthenes

Tenth graders create maps to a secret location on the school grounds for others to follow, study topographical maps, estimate the size and shape of the Earth, explore various formations of the Earth's topography, and give an oral report...

Students use principles of geometry to measure the circumference of the Earth. In this applied geometry lesson, students use mathematics to determine scientific information. They make measurements, calculate the central angle, and use...

Students, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of the...

In this science worksheet, students take home a worksheet describing the way the sun shines on earth including how long it takes and the days when there is more sun and no shadow. The parent sign and return the worksheet.

Students familiarize themselves, through teacher demonstration, with Gavendish's apparatus first used for experimentally determining the value of the Universal Gravitational Constant G, and calculate theoretical value of Earth's...

Students explore geometry by conducting a science experiment. In this circumference measurement lesson, students review the Greek geographer Eratosthenes who first discovered the circumference of our planet. Students utilize...

Students explore the tools used by Columbus to chart his latitude. They study the change of a location over time.

Students study the earth in relation to the solar system.  For this planetary lesson students complete several investigations into the measurement of the earth and its magnetic field.

High schoolers engage in a historical review, starting with the existence of the horizon at sea, proceeding to various studies of the Earth's size and shape, and leading to the attempt by Columbus to reach India by sailing westward.

Learners use their geometry and trigonometry skills to determine the distance between their school and another school.
