Estimates put the asteroid at ~17 meters in diameter with a mass of ~11,000 metric tons and traveling ~18 km/sec. This NASA created math activity can be used in classrooms to use a real world headline making event in their math lessons.
Here’s a nifty math and physics games that teaches graphing in a practical way. Be sure to point out to your students that gravity is not a factor here.
