Megan's questions

A few afternoons ago Megan walked around with a small notebook and a pencil. "This is my notebook of questions," she said. "My first question is, 'how does a rocket make it out of the atmosphere?' Mom, does a rocket just go so fast that gravity can't pull it down." I said, "Yep, that is basically it."

"My next question is, 'how big is the sun?' Mom, can you google that?"

"Do you want to know how heavy the sun is?"

"I want to know how big it is from the top of the sun to the bottom." So we looked up the diameter of the sun.

"My third question is , 'how does an airplane stay up?'" I pulled up a diagram about Bernoulli's principle and we talked about air speed, air pressure and lift. 

"Keep that picture on the computer. I want to draw it in my notebook, but I will put five arrows under the wing and four on top so I remember that there is more pressure pushing up."

"And Mom I brought home one book about space and one book about NASA from school. Can I get the space books from downstairs too?"

Yes, Megan, you sure can.
