Physics Newtons third law high school physics project Video demonstration

Question:
I need ideas on physics experiments which are not too basic. preferablly something that includes sound, speed, temperature. Something exciting would also be good as physics can get a bit lame. I suggestion that i have been given is to use presureised water rockets and measure the distance the rocket goes at different pressures, but due to water restriction our bubble burst on that one.
all help will be appreciated.
thanx
Question:
physics experiments like foot pressure, dispersion, torque, equilibrium and any other experiments relating to physics…what is it’s importance to the nursing course?what are the concepts?

Question:
I’m a sophomore in high school but I’m taking A&P next year along with Physics. I’m not /that/ great at science, but I took Bio as a freshman (instead of Earth Science) and Chem now (instead of Bio). Then again, it’s always been my only non-honors class. I’m a strong, well-rounded student but I’m just a little worried about Anatomy since like I said earlier, I’m not AS GOOD at science as I am at say, English or History.
From what I’ve heard, Anatomy is a LOT of memorization but I think I should be okay with that since I’m pretty good at memorizing things. Also it sounds interesting, so that would keep me motivated to do well in the class, but I have friends who are in Bio Honors and have the teacher who is going to teach Anatomy next year, and they all say he’s evil. I’ve even heard from other teachers that he’s very meticulous. Apparently he said Anat is almost as hard as an AP class, but not quite…
What do you think? And also what’s a good Anatomy textbook to use as a resource? Maybe I’ll start looking through one this summer. Anatomy would be my second elective, making that 7 credits next year, so I would be taking two lab sciences next year, as well as French and Spanish 3, AP Lang & Comp, and AP US History. I could always drop A&P since I’m taking way more credits than people normally do, but I feel like if I could push through everything next year I would emerge a stronger student (and, it’d probably look good for colleges, too).
Question:
I know that the error for individual measured values can be obtained by computing the standard deviation of the measured values (i.e. measure value±std. dev.).
For example: measured values are A,B,C,D,E ; std. dev. of A,B,C,D, & E=sd
So (A±sd),(B±sd),(C±sd),(D±sd),(E±sd).
How many significant figures should I retain for sd / the error?
*Some resources say it should be expressed to only 1 significant figure. But some express uncertainties to more than 1 significant figure. Like my teacher in Physics who wrote a comment on one of our lab reports.
(0.9538±0.0106)ms ———->my computed value(my teacher said this is wrong)
He told me that error begins at the hundredths place. So it should be
(0.954±0.011)ms, because error starts with 1 and a second figure which also 1 in the measurement must also be taken.
What is really the rule for retaining significant figures in an error?
Question:
A student wishes to measure the resistivity of glass. A teacher suggests that its resistivity is of the order of 10^6 Ω m which is very large.
Resistivity ρ is defined by the equation:
ρ = RA / l
where R is resistance, A is cross-sectional area and l is the length of the material.
The student is given a number of sheets of glass of the same thickness and of different areas.
Design a laboratory experiment to determine the resistivity of glass. You should draw a diagram showing the arrangement of your equipment. In your account you should pay particular attention to
(a) the procedure to be followed,
(b) how the glass would be connected to the circuit,
(c) the measurements that would be taken,
(d) the control of variables,
(e) how the data would be analysed,
(f) any safety precautions that you would take.
**If its possible then do send me your answers as pics or resources which will be helpul!**
@markum, hey thats the kind of answer i was looking for…thanks
But i’m confused at the orientation of the glass when connecting it to the ohmmeter.
Could someone please explain which way it should be?
ANY ONE CARE TO ANSWER THIS!????
Question:
Recommended resource sites, books I should read, stuff I should know….
I have always been fascinated by physics but the teacher’s did not sing a good song about it. I managed to barely get a 90 in my grade 12 class but I want to know more it hardly seems that that’s it!
And my son has taken quite a shining toward physics… But he’s 8… maybe if I teach him we can go through it together 
He’s so fascinated but nothig to quench his thrist for knowledge!
Mind you he brought it out so boringly that I was always half asleep…. But I took my past teacher’s advice and always made notes and made sure I understood something in all of our classes.

Question:
how come all the really interesting physics research, like the LHC and ITER, done in Europe, specifically, France?
i think it’d be neat to work on this but i cant speak french!
Question:
Hope you’re having a good day. My physics teacher assigned a sciene experiment; and 2 days from now, we have to have an experiment thought up / picked out. He does not want it to be biologiy related (eg: plant growing one). He wants it to be a physical sciene related one. he gave a few suggestions; which batter brand lasts the longest, which toilet paper brand absorbs the most liquid, does reaction time vary at different times of the day, etc.
I don’t have a lot of resources and don’t want to do anything I can’t test; he said we have to be able to take 3 pictures to prove we are doing the experiment, record reliable and accurate data, and be able to make a graph, pie chart, or something along those lines with the data. Does anyone have any suggestions?
Question:
My teacher has rejected all of mine and I am in a big dilemma since I am a senior and I’m in hopes of winning a scholarship at the Regional Science fair.
He said it could be on any topic and can include engineering.
I guess I’m freaking out because I need to submit an outline by Friday and still don’t know what I should do. I have scoured the internet but have not found anything creative and/or challenging.
Complexity really isn’t an issue nor is time. I just want something that will give me hopes of winning. 
Resources would be nice as well.
Thanks so much!
I also have access to MIT’s labs so the sky is the limit.
the trebuchet idea is really good but i’d probably use it for more harm than good.
