Science fair project?

Question

Science fair project?
my teacher wants me to apply my science fair idea to everyday life. dose anyone know how the porosity and permiablitlity of objects (dirt,sand,graveletc..) relate to daily life.
PLZ HELP!!!

Answer 1

Well, the easiest example is construction. Certain materials are better than others. When building skyscrapers, they have to formulate a cement that is extremely strong but also very light. Porous materials will obviously be lighter.

Also in gardening, you don't want to grow your veggies in clay because clay is very difficult to dig through and tend. In other words, it isn't very permeable.

Answer 2

An easy experiment that would have great practical importance to everyday life is water permeability as it relates to building foundations.

At some point in your life, you may be faced with the problem of water leaking into the basement of your house. Many people are dealing with this problem right now.

The most difficult aspect of the project is to keep the scale of the models small. I'd suggest a railroad scale of 144:1 so that you can purchase some nice looking homes and landscapes. Like an ant farm, construct plastic cut outs for model homes with different soil types. You can put in a drainage field and plastic tubes (maybe straws) to show how a passive drainage system would work.

If you were ambitious, you might even consider a small hidden sump pump in the basements, so you can run the demos over and over again. You could have it be an unattended model with buttons that little kids would like to try out.

You might do some research on basement flooding so that you can build a house with water problems and a house with proper fill and drainage.

I'd limit the homes to two or three so that you don't overwhelm the audience with too much information.

Answer 3

DO A MEMORY ONE.

SURVEY DIFFERENT PEOPLE OF DIFFERENT AGES WITH A MEMORY TEST. SHOW THEM 15 EVERYDAY ITEMS (KEYS, QUARTER, PAPERCLIP). GIVE THEM 5-10 SECONDS TO MEMORIZE, THEN COVER IT WITH A TOWLE OF SOME SORT.

MAKE SURE YOU USE THE SCIENTIFIC METHOD AND DO A REALLY GOOD JOB WITH THAT CUZ THATS ALL TEACHERS ARE LOOKING FOR.

ALL LOST FAILS...DO A PAPER TOWLE TEST.
