Let's start by...

....taking a deep breath. In all likelihood, you've heard things about taking physics. Maybe scary things. Let me tell you this loudly, clearly, and from the get go.... physics isn't hard.

Ok, that statement might be a little misleading, but the point is that physics doesn't have to be hard. That's my approach. We're going to be learning what I like to call "practical physics." You know, learning about why things work and act the way they do. We'll throw in some of the essential math (you can't have physics without math; that's like having music without notes), but this won't be a course in number crunching. We'll be doing things "hands-on," creating full-scale demonstrations/experiments, gathering our own data, and do all that in order to identify the laws and forces at work in our world.

So, welcome to a year of learning and investigation together. And let me emphasize the word "together." Learning is a two-way street. I'll do my job, but it's up to you to carry your end of the bargain. Engage in the learning, ask questions, be a team player, and follow through on the handful of responsibilities thrown your way. That's what makes good teamwork and that's what makes good learning.

Let's do it.

  2. Get a hard boiled egg and make a small hole on the top and bottom, put your mouth on the top and blow on it as hard as you can in one quick spirt, the whole egg will shoot out of the shell completely intact. Why does this happen.

  5. Why are seasons different around the world? As in, why is it summer in one place when it's winter in another? How is it related to a part of the world's proportion to the sun? When does the world rotate exactly so that one half of the world is facing the sun while the other is not?
