Thread: Need help for science assignment please!

True. Not much science in it.

fit hiclones to each vehicle and test kpl with fitted and without, then post results, this way we have an unbiased assessment if they are snake oil once and for all

Im totally stuck on choosing a question so Im hoping that someone here can help. I would be pretty cool if it was car related. I could do some experiments on the 3 cars in my family an old toyota camry, Kia sorento and a Jaguar (mine). P.S I also have to have an independant and dependant variable and stuff like that. Cheers!

Hi Tom

OK: "scientific method" is what the teacher is trying to instill.

so, to start with you form a "hypothesis": that is, a statement which you think is reasonable, based on some hunch you've had... /observations you've made

so you write down your hypothesis then design an "experiment" to test it..

Within the course of the experiment, you make a series of "observations" or measurements, keeping everything exactly the same except one variable. On the basis of that changing variable you observe/measure the change in the other measurements.

For example: we had a long legged blonde in our uni biochemistry class. a gorgeous kid with a great sense of humour (and straight "A"s!). So, one of our number hypothesised that if she were to wear a thick pantyhose on one leg and no pantyhose on the other leg, her upper bare leg might grow thicker in the Canberra winter due to fat deposited there to keep her leg warm.

So, every monday morning before the lecture (there were only 9 of us in the final year class by that stage) she would stand on a chair and said chap would produce the tape measure and take a reading 100mm above the knee...

there was no discernible difference in (upper) leg diameter after 3 months of measurements...

The relationships between l/100km and load weight etc etc are fairly obvious because the more effort expended by the engine the greater the fuel consumption

Stuff which is a bit quirky and from which you can produce easy graphs etc is always interesting (like the leg diameter!) and is sure to get a good mark...

So think up something simple and lets have it, then think about how you will measure it...
