6th Grade science project using .22

[Duffster]

Where heck you buying .22 ammo these days?

I just thought I would offer it up in case anyone else needed a project idea.

That project idea at most schools now-a-days would result in the intervention of a swat team!

"Eh!" to the posters that want to contort this important issue into politics.

When my daughter was casting about for a science fair related project, I told her you can't go wrong with a project involving water balloons. The idea, of course, is that to stimulate a student interest in science or math, physical impact captures the students' imagination more than charts, graphs, and rhetoric.

Water balloons, controlled explosives, potato guns, whatever- as long as the students don't get hurt too badly, you've cultivated a crop intellectually curious students. The actual societal risk is not so much from supervised risk as it is from entire classes falling asleep at their desks.

Maybe it's just me but I found ^that^ to be very funny! :laughing:

We had a sheriff deputy a few months ago that gave his kid a bit of cocaine from the office for show and tell. Still employed as far as I know. I don't trust cops or elected folks or the schools.

here in N. Idaho that might be allowed...if school was asked first. But not sure.

Its too bad that the nuts have taken over. I used to go to high school and college with my trusty Model 94 Winchester in the back window of my truck. no one cared. I even had my reloading unit set up in my dorm room back in the early 1980's.

i miss the old days. you could have this new world order kra*

This may be a little off topic but science projects are intriguing for both the creators and the observers...They make us think about things we may not be familiar with...and possibly inspire young minds as well as old...

Seeing the topic "science project and .22"...made me remember a lesson in physics...how velocity does not effect gravity .i.e., a propelled mass will fall at the same rate as an identical mass that is simply dropped from the same horizontal plane...

21 years in Naval Aviation... Gravity always won. The hard boiled egg into a milk bottle opened my eyes.

In the "Olde" days and I do mean "Olde" days, before any kind of electronics. they measured velocity with a thing called a Ballistic Pendulum and a lot of mathematics. The idea was you fired a round at a pendulum of steel of a known weight, on a knife edge "bearing" and attached to the pendulum was a cloth tape measure that when the pendulum moved backwards it drug this cloth tape measure thru a slot and of course when it moved the other way the cloth tape measure did not move backwards. You then read the tape measure to determine how much the bullet moved the known weight pendulum and from that you could calculate with a given bullet weight what the energy was striking the pendulum and work backwards to calculate the velocity of the bullet.. All very imprecisely I might add..

We used to do that as a lecture demo in the physics dept.
