content: i need a list of things i could do for club i am hosting during this summer. i know i should go over the basics and other things but what all could i do you know like 555 or going over what is an led cause i need and electric ( or just "science" ideas) side to my projects i have a lot of ideas already just need more. thanks for any help i can get ( posted in beginners because i need beginner projects)

content: When I think "science" I don't immediately migrate toward electronics. If it's actually a summer "science" club, you may want to focus on physics or chemistry or similar. I'd say those are the more "traditional" sciences. Explaining the chemistry (science) behind some electronic devices is... complicated.I'd build a catapult. Then use it to study projectile motion! (And you can throw some other physics concepts in there too if you built an onager instead of a trebuchet.) Everyone loves catapults! Then you could even think of a way to make it launch using electronics if you wish to bring electronics into it.

content: i know when people think science the don't think electronics but yea my ideas are also chemistry and physics but i want to get away from the traditional " science fair volcano". i want to go my own way from the norm of FUN SUMMER "SCIENCE". so yea my ideas are to be able teach people about the science of electronics not chemistry as much.a van de graaff generator or a Tesla coil i have looked into but would be to much money or at least $50(USA) for me to get or even make.

content: i will be thinking around i will have till September so about 20weeks and 4 divisions so chemistry, physics, electronics and then mixing them together.my first ideas for this are1. ohms law messing with leds2. ohms law messign with 555 / sound with 5553. making the thing at the end of this4. ?5. ?my price range will prolly be around 100 to 150 dollars but hopefully i wont have to spend that much and will also depend on how may people join in on this "club"

content: age group. well 12 - 17 so enough learning but also enough blowing crap up to keep them wanting to come back

content: Well a few standard impressive ones (chemistry related) are:Dry ice in hot waterBarking dog reactionThe Briggs–Rauscher oscillating reactionElectrolysis and hydrogen capture (explosions!)etc.There are loads here too:http://www.stevespanglerscience.com/lab/experiments/category/densityYour budget is quite limiting, really. For chemistry perhaps a school will let you "borrow" a few things...and don't forget 'safety first'. Parents won't be happy if you maim their kids.For electronics, you can do the classic 555 flashing LED, maybe a counter/stopwatch, if you want to mix up physics and electronics you could do a stopwatch/gate system to time movement from one point to another...I'm sure some more will come to me, I'll post more if they do.

content: (1) If you have a good basement, build a pendulum and measure how it also go around in circle. (The plane the pendulum swings should be slowly rotating if you leave the pendulum undisturbed). You have to figure out how to make the pendulum swing long enough for the plane's rotation to be measurable.(2) Have two pendulums. First, have a wire that goes say the X direction, have both pendulums be of un-equal length, both tide to the wire at the fixed end, and have both pendulum's swing-plane in the Y direction. Measure how one pendulum affects the others. (Energy will transfer from one pendulum to another with the wire being the medium of energy transfer.)(3) Try it with three pendulums (of equal length). (a) See if you can work out the "why's" on what you see, and (b) do research on the math.(4) Try using a shorten middle pendulum. (a) See if you can work out the "why's" on what you see, and (b) do research on the math.(5) Now work out the math what youshould seewith #4, but change the middle pendulum to twice the length of the two other ones. Last-build these three pendulum and see if what you worked out theoretically matches what you see after you have them swinging.Budget: 3 bowling balls, some Delrin type plastic, some wires, some 2x4 wood stud...

content: i have a feeling that would be a two apart idea for the pendulums. so its goodbut what chemicals could i mix that when mixed become something that can conduct electricity but only when it is mixed. cause that could count on both electric and chemistry

content: In a science summer school many years ago I watched a demonstration of water hammer, given by a hydraulic engineer, a good flow of water through a copper pipe coil would bang when a quick action valve was shut and make a lot of noise getting everyone's attention, he then deliberately increased the flow such that a rubber hose connection to the copper pipe then burst, spraying the audience with water, he pretended it was an accident, appeared to get flustered, apologised, all the audience was laughing but paying attention, he then had the audience in the palm of his hand and raised issues of water hammer in big pipes. Science doesn't have to be serious to learn.
