Grade 5 / Topic: Electricity and Magnetism
MAGNETISM is a full dome planetarium show that demonstrate s how the Earth’s magnetic field protects our planet from energetic particles from the Sun and galaxy, and how the magnetic field also protects the water in our atmosphere from being swept away by the solar wind.
MAGNETISM is everywhere: from magnetic fields surrounding nearby worlds to the red auroras on a distant brown dwarf; from magnetic field recombination causing Earth’s auroras to the navigation of animals and humans around the globe; and from maintaining Earth’s atmosphere to shielding Earth’s surface from cosmic rays and the solar wind. Most often heard comments from show audiences are “wow”, “beautiful” and “I learned a lot”.

HOLD METEORITE SAMPLE FROM METEOR CRATER
The students will enjoy holding a 440gm sample of meteorite from Canyon Diablo meteorites that arrived 49,000 years ago into North Central Arizona, forming Meteor Crater. Meteorites are 4.6 billion years old; so, when you touch a meteorite (any meteorite) you touch the oldest object you will ever touch.
The sample is made of nickel-iron that classified as Coarse Octahedrite Iron Meteorites. The sample shows thin sharp edges and twisted metal are typical features of the meteorites from Meteor Crater. Students will test the meteorite by using a magnet and they will test how heavy is the sample.
