I know a couple of them, like "Schist happens", "Geologists, don't take them for granite", and "If you show me your outcrop, I'll get a little boulder". Does anyone know any othes that they would like to share?

Here's the detailed info on where the showers are, but what does it mean in layman's terms:

The duration of this shower extends from July 15 to September 11. Maximum seems to occur during August 1 (Solar Longitude=128.6°) from an average radiant of RA=306.7°, DECL=-8.3°.

If I'm in North America, would I take a compass, point 0 degrees to the north, then look at the 306.7 degree mark and face that direction? Then look up 8.3 degrees (If 90 degrees is straight up, then about 1/10th of the way between the horizon and straight up).

Does this sound reasonable, or am I way off?

I work in a Title 1 school and I need lessons that are on a fairly basic level...but worth the student's time. Web sites would be helpful. This is the first of the 8th grade science standards in California.

I understand that particles have different "charges" positive and negative. But what EXACTLY (if we know) causes particles of like charge to be repelled from one another.

It seems to me that they're exerting some kind of outward pressure or something in all directions. Such that, when these pressures collide, they kick back (each action has an equal and opposite reaction), thus keeping the particles themselves from ever completely colliding.

But do we know the MECHANISM by which this happens? Say we have two electrons, and we try to push them together, their electrical charge keeps them apart, and the more we try to push them together, likely the stronger they're pushed apart. But WHY? Or is this one of those "you could base your PhD on it" type questions?

When speed is bigger, mass is bigger.
But speed is bigger than what? And when we measere mass in two different speed, we get two different mass? And how to measer speed at two different speed? So is mass the property of the thing AND the measurer? (Than I'm only 77 kilos:))

I know the space shuttle enters the atmosphere at very fast speeds and thus reaches EXTREME temperatures and so the need for the heat shield. My question, assuming fuel resources, why can't the space shuttle slow down sufficiently to enter the atmosphere slowly? Someone mentioned to me that at slow velocities they would bounce off. WHY???? It is not a hard object, so why can't they just gradually push through??? Confused!!!! Thanks!!!
