Only two years after it was broken, the world record for the highest skydive has been rewritten. Google executive Alan Eustace set a new mark Friday when he fell from an altitude of more than 135,000 feet, plummeting in a free-fall for about 5 minutes before deploying his parachute. The jump broke the record of 127,852 feet that Felix Baumgartner set in 2012.
How does a sunset work? We love to look at them, but Jolanda Blackwell wanted her 8th graders to really think about them, to wonder and question.
So Blackwell, who teaches science at Oliver Wendell Holmes Junior High in Davis, Calif., had her students watch a video of a sunset on YouTube as part of a physics lesson on motion.
"I asked them: 'So what's moving? And why?'" Blackwell says. The students had a lot of ideas. Some thought the sun was moving, others, of course, knew that a sunset is the result of the earth spinning around on its axis.
