When introducing argumentative writing to students, describe it as a debate on paper--with both sides represented by facts, evidence, and relevant support. It's similar to the closing arguments at the end of a Law & Order episode. Consider showing clips of the closing arguments from various trial scenes.
An artist's impression of what the Mayak satellite could look like once in orbit. The proposed 'Mayak' satellite would have a huge pyramid-shaped reflector to make it easily visible in the night sky. A group of Russian engineers has raised over Â£17,000 to launch a reflective satellite which would be one of the brightest objects in the night sky.
Artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. Satellites can even have people in them, like the International Space Station and the Space Shuttle. The first artificial satellite was the Soviet Sputnik 1 mission, launched in 1957. Since then, dozens of countries have launched satellites, with more than 3,000 currently operating spacecraft going around the Earth.
