the oil drop experiment was to determine what?

Do you mean the experiment where you measure the size of an oil drop, then place it in a petri dish that has talcum powder or some such on it. The you measure the size of the pool of oil in the petri dish?\n\nIf so, this experiment was to calculate the approximate size of a molecule. \n\nEssentially, by measuring the diameter of the droplet of oil you can work out its volume (πr3). Then the nature of oil on water is to settle until it has reached a molecule's height and then to disperse. So, at its peak you measure the radius of the circle formed in the petri dish and you can work out how big the area is (πr2). \n\nThe volume of the new pool is then \n\ninitial_voume/secondary_area =  molecule height\n\n\nDoes this answer your question?

Great idea.  What is your hypothesis?  What experiment will you do?  What data will you collect?  How will you interpret it?

Simply put, you can look at light or matter as waves or particles, depending on the experiment performed.

Use the second derivative test, not sure exactly what it is still but it should be easy to find on the internet.

i believe the thing they used is called a calorometer. it involves burning the food and measuring the amount of energy that is released during combustion.

Hi. The experiment used a torsion scale, a very thin wire with known strength, to support the center bar. The smaller balls were attracted to the larger ones and caused the wire to twist just a little. From this the mass of the lead balls was used to calculate 'g'.

Not yet - that's what scientists are trying to determine.....

u can do an investigatory project about the different uses of coconut or about the usefulness of coconut oil..

First guess: Oil (assuming an oil spill) might coat plant surfaces restricting photo synthesis.

Experiment w/ what works for you.

I would refine the problem some more first.\nResearching "the impact of objects on wood" is a little vague.  What type of objects?  What do you mean by "impact" in a scientifically testable way?  What type of wood (not just "oak" or "pine", but wooden boards?  wooden chairs?).\n\nThink of what your controls for the experiment will be, what will be your variables, how will you test, ...\nFollow the scientific method.

Oil is less dense than water.

Are you talking about Dr. Emoto's experiments?

I am not quite sure what the question is. What should the manufacturer do? Did they already do the experiments or do you want to know what sort of experiments to do? Do you want to know how to reduce the data? How to present the data? What statistical tools might be useful?
