Classroom physics: free body diagram of Ariane 5
StandardI’ve been recently teaching Physics to 8th graders. We have finished the chapters on motion, forces, and friction, and just covered gravity. As part of this chapter, though not included in the curriculum or book, I introduced the concept of the free body diagram [1]. In the first session introducing this concept, most students didn’t really grab what it is or why it is important.
For the last session before the vacation, I started the class by playing a video of the Ariane 5 [2] launch that occurred on 29 August 2013 of the French Guiana:

Warning over lack of science practical lessons (BBC)
Link“Smartness” and “Intelligence”
QuoteMany people assume that superior intelligence or ability is a key to success. But more than three decades of research shows that an overemphasis on intellect or talent—and the implication that such traits are innate and fixed—leaves people vulnerable to failure, fearful of challenges and unmotivated to learn.
Teaching people to have a “growth mind-set,” which encourages a focus on effort rather than on intelligence or talent, produces high achievers in school and in life.
Parents and teachers can engender a growth mind-set in children by praising them for their effort or persistence (rather than for their intelligence), by telling success stories that emphasize hard work and love of learning, and by teaching them about the brain as a learning machine.
