Alpha Monocerotid meteor shower, predicted to peak around pm ET on Nov. An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds found in meteorites.
New research shows streams of meteoroids striking the Moon infuse the thin lunar atmosphere with a short-lived water vapor. A meteor that does this is known as a meteorite. Show the class the photograph of a meteorite.
This meteorite was found in a Saudi Arabian Desert. Notice how it stands out against the yellow rocks. Explain to the class how it is much easier to find meteorites in places where they stand out. Ask the students to discuss where it would be easy and difficult to find meteorites. Easy — deserts, plains, sand dunes and on ice in Antarctica. Difficult — forests, lakes and seas. Some meteorites are large enough and travel fast enough to create a crater on Earth when they impact.
Ask the class what would the effect size be of a crater caused by a meteor. Mass, impact speed, impact direction, type of ground it lands on. It was the first in the world to be positively identified as a meteor crater. It is possible to recall the extinction of the dinosaurs by the dust cloud from a meteor strike if the class has previously learned about this.
Watch the following video of the Chelyabinsk Meteor in Russia in www. The video may not be suitable for younger children. Explain to the class the dangers of meteor strikes. They have an immense amount of energy and can cause massive destruction. The shockwave reached the people much after they saw the light because of the difference between the speeds of light and sound.
Explain that the shockwave caused windows to shatter, and 1, people needed hospital treatment for injuries mostly because of broken glass from windows.
Image: a small meteorite — a fragment of the Chelyabinsk Meteor after it exploded. Consider following this activity with an experiment about impact craters, e. Meteoroids, Meteors and Meteorites Learn about formation of meteroids. Learn the difference between meteoroids, meteors and meteorites Learn that shooting stars are not stars but meteors Learn that meteorites can affect life on Earth Learn about the origins of meteoroids.
Explain the differences between meteoroids, meteors and meteorites Demonstrate how meteoroids are formed using flint stones. Students will demonstrate how small pieces can break off when two asteroids collide or when a comet warms and begins to melt.
