Demonstrate that seasons exist because of the tilt of the earth and its impact on the intensity of the sunlight at a given location.Difficulty: Elementary schoolHow to build a homemade magnetometer to study how the earth's magnetic fields are affected by solar storms
Solar storms can affect the Earth's magnetic field causing small changes in its direction at the surface which are called 'magnetic storms'. A magnetometer operates like a sensitive compass and senses these slight changes. The soda bottle magnetometer is a simple device that can be built for under $5.00 which will let students monitor these changes in the magnetic field that occur inside the classDifficulty: High schoolHow to build a sidereal pointer to help us to locate the position of a celestial body
In this article, we talk about the construction of a sidereal pointer. It is an instrument that allows you to localize each celestial object in the night sky, just knowing its coordinates.Difficulty: Elementary schoolHow to calculate the distance of the sun and the moon from earth, by understanding eclipses
Hipparchus, who used an eclipse of the Moon to deduce the precession of the equinoxes (here), used a total eclipse of the Sun--probably in 129 BC--to estimate how far the Moon was. That distance had also been derived from a lunar eclipse by Aristachus--see here.Difficulty: High schoolHow to make your own comet
In ancient times, people did not understand the objects in the sky, how they moved or what they were. They did not know what a comet was, where it came from, or where it went. A large comet is a spectacular sight and inspired both awe and fear in primitive peoples.Difficulty: Elementary school
