PPT – How greasy are your potato chips

To ensure that the experiment is a fair test, I would make sure
that the potato chips all have the same volume (diameter, length
and similar masses).

Also, I wanted to use the results I have after completing
the experiment so that I can have an overview of how
of different strengths affect the diffusion of water in potato chips.

I thought that the lengths of the potatoes will change after the
experiment because there had to be some movement in or out of the

Scientists are still arguing about fat, despite a century of research, because the regulation of appetite and weight in the human body happens to be almost inconceivably complex, and the experimental tools we have to study it are still remarkably inadequate. This combination leaves researchers in an awkward position. To study the entire physiological system involves feeding real food to real human subjects for months or years on end, which is prohibitively expensive, ethically questionable (if you're trying to measure the effects of foods that might cause heart disease) and virtually impossible to do in any kind of rigorously controlled scientific manner. But if researchers seek to study something less costly and more controllable, they end up studying experimental situations so oversimplified that their results may have nothing to do with reality. This then leads to a research literature so vast that it's possible to find at least some published research to support virtually any theory. The result is a balkanized community -- ''splintered, very opinionated and in many instances, intransigent,'' says Kurt Isselbacher, a former chairman of the Food and Nutrition Board of the National Academy of Science -- in which researchers seem easily convinced that their preconceived notions are correct and thoroughly uninterested in testing any other hypotheses but their own.

It is important to repeat experiments so you gather plenty of information.

Repeat steps 1-6 for the other three varieties of potato chips and potato crisps.

So measuring the lengths of the potato chips before and after the experiment will not really prove the osmosis theory to be right.

Are all potato chips equally greasy?

The results of my try-out test:

Concentration of sucrose solution

Length of potato chips before the experiment (cm)

Change in length (cm)

The mass before the experiment in grams

The mass after the experiment in grams

The change in mass
















I only tried four different solutions on my try out test instead of
using all six different strengths is to see if my method worked as it
should do.

Do you notice a grease.Procedures Repeat steps 1-5 two more times so that you have a total of three trials for this bag of potato chips.

[potato chips] because of salt — greasy

I will also measure the length of the potato chips before and
after the experiment to compare if there is changes in the lengths
of the potato chips

Analyising Evidence and drawing conclusions:

The graph of my results:


*Note: On the graph above, if the point is below zero, then the mass
of the potato chip has decreased.

Hurricane Irma Is Now Heading Towards West Florida, …

As you can see for the graph of results from above, you can see
that the potato chip that had increased the most mass after the
experiment is the one in the 0M solution and the potato chip that had
decreased in mass the most is the one in the 1M solution.
