it's due thursday, and i need to do quantitative observations (with numbers) it's like my only good idea, so i need help please!

You may be able to suspend a (square?) (wooden?) target at each end (from a horizontal broom handle, etc.?) and swing a fixed weight (ball pendulum?) against its exact center from the same pivot point. By "coating" the target with different materials (rubber, various thicknesses of wool cloth, cardboard, etc. you can note the deflection of the target which should vary depending on how much energy was absorbed during the shock relative to the naked target. Release the weight from the same height (horizontal?) and measure the deflection (using a ruler?) and convert observations to angles. Or include a cardboard arc graduated in degrees. Trials may be repeated and averaged as long as samples do not deform. Be sure the weights of the materials are about the same (vary sample size?). Record results for various targets. Good luck.

Unfortunately, the egg measurements are going to be kind of binary (either it breaks or it doesn't). In order to get a real measurement of vibrations, you would have to use an accelerometer. This would give you a quantitative measurement of the g forces and thus tell you how well you're absorbing the vibrations. I'm guessing you won't be able to get one of those by tomorrow.

Drop an egg from some specific height on to different types of materials like a pillow, stack of newspaper, crumpled paper, etc. Then find out which of the materials absorbs the shock of the egg landing the best (break/no break).

What is doing the absorbing? I would just have a ruler and measure it uncompressed and then with a variety of objects, see how far it is depressed (at maximum)
Use the millimeter scale (sounds so much more scientific)

using a spring scale

you could use eggs.. you could assign different numbers if the eggs are undamaged, slightly cracked, or completely crushed..
