Re: [Phys-l] outdoor experiments



Water and air rockets are very nice.

This Water Rocket launcher from Pitsco is very reliable and pretty tough. They sell cheaper models though. Figuring out the optimum amount of water is pretty cool and it isn't terribly hard to use a rocket site to measure how high the rocket went. High speed photography is also pretty cool for measuring speeds along the flight.

Air rockets are also amazing. I like this set from Arbor Science. Reliable repeatable firing, even at angles. Less to do than water rockets, but the fire impressively high.

If you have a smooth athletic court like a basketball or tennis court, hovercraft of all sorts are amazing. You can make your own hovercraft or get a kit from Pasco. Consider getting a gasoline powered blower for outside use. They are very loud, but they will run for hours rather than the minutes of a battery power, and with the extra air they will levitate much heavier people.

Subject: [Phys-l] outdoor experiments

hello,
i am a physics and math high school teacher;
thanks for this
excellent mail list !

i'd like to ask you information about possible
outdoor experiments you
do or have done in the past;
by outdoor
experiments i mean a wide range of experimentations that
can be carried
outside and not simply inside a lab; i think it may be
fun and engaging to
study the behavior of some physic system taken as
it is and not artificially
reproduced in a lab;

of course, it may be only a preliminary phase, since
many experiments
should also be carried inside the lab as always;

if
it is not really clear what i mean, just tell me and i'll reply

thank you
in advance
