Eratosthenes And Radius of the Earth

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

Students conduct scientific investigation in which they observe glacial effects on landscape, develop and explain their own theories of how glaciers change land, and demonstrate understanding and explain basic motion and force principles.

In this black holes activity, students use a formula for time dilation which causes delays in events that occur near the black hole. They solve 6 problems using the equation.

Students use data collected by an astronomer to determine the relationship between the time it takes the planet to orbit the sun and the average radius of the planet's orbit around the sun. Students use trial and error to find the...

A profile of the ancient Greek mathematician, geographer, and astronomer, Eratosthenes. Looks at his many accomplishments, including measuring the circumference of the Earth and the distance to the Moon and the Sun. Includes links to...

For this task, students must investigate an experiment by Eratosthenes where he estimated the circumference of the Earth. It requires collaboration with at least one other school. Aligns with G-MG.A.

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...
