- Project Question: I'm comparing the strength of rubber bands 1) with the same length but a different width and 2) bands with the same width but a different length to see which is stronger. I see that others on here---they were testing the effect of temperature on them---have made a point to measure the length of their rubber bands as they're being stretched. Is that necessary in my case, and must I address Hooke's law, which seems very complicated?

Patellar Reflex Measurements
How can I measure patellar reflexes for my science experiment? (I assume they must be measured, if I say that they are affected by certain stimuli.)

Re: Patellar Reflex Measurements
Hi,
Can you be a little more clear, please? What exactly are you trying to measure about the reflex? What is your experiment testing?

Re: Patellar Reflex Measurements
I have changed my experiment. Thanks anyway! Do you know anything about saltine crackers?
I am testing 5 varieties made by the same company, to see which absorbs more liquid. Nabisco won't divulge any "proprietary" information that will clue me in as to why some types absorb more liquid. I was hoping to be able to explain my test results. Instead, their customer service reps only offer that it "probably has to do with their ingredients" or "air pockets", which vary from cracker-to-cracker. Note: Most of them weigh the same before being soaked, but some hold more liquid, on average. I just want to know why? I can only speculate, and I don't know if that will be good enough for the judges.

Re: Patellar Reflex Measurements
I can't say I'm an expert in saltine crackers, but I would check the ingredients for any differences between the crackers and look up those ingredients to see if you can find anything out.
