Cuevas SURVIVAL
IN
THE
WILD.
WATER FILTRATION EXPERIEMENT .
Imagine you get stuck in the middle of no where. Stuck in the wild with nothing but a back pack, the contents of that back pack, and the clothes you are wearing. You are walking around finding your way back to civilization but it's getting dark and you are hungry, tired, and thirsty. You find that you have a nutrition bar to eat so you are fine but, you find out you have no drinking water. You now realize if you don't get some soon you may be at risk for dehydration and maybe even worse. You realize you must now do something to save your life. You look through your back pack to find that you have plastic cups, toothpicks, and the elements around you. You then remember the science experiment you did in class about water filtration. It now is apparent you must make a crude yet effective water filter system in order to filtrate the water you have found in a brackish creek. You also decide the best thing to do is grab your bra and use it along with sand soil and gravel to filtrate the water. Did I forget to mention you're a girl?
SO NOW THE QUESTION IS; WHICH FILTRATION SYSTYEM WOULD WORK BEST?
HYPOTHESIS:
YOU BELIEVE THAT THE BEST FILTRATION SYSTEM WILL BE THE BRA CUP, SAND, SOIL, AND GRAVEL ALL TOGETHER.
EXPERIMENTATION TIME!
ITEMS YOU WILL NEED.
- SMALL PLASTIC CUPS
- SOIL
- SAND
- GRAVEL
- BRA CUP
- Kool-Aid mixed with water NO sugar added(TO SUBSTITUE THE BRACKISH WATER)
- TOOTHPICKS
- First get seven cups(two for each of those seven)
- Label those cups
- Then with a spoon use that to pour the soil to it's first cup, do the same with the rest of the gravel, and sand. (Make sure all of these are equal amounts of only one spoonful). This will be done in a order though, first one cup by itself only containing soil. Then another cup containing both soil and sand, and last a cup containing soil, sand, and gravel. This process will be continued with the bra cup as seen on number five.
- Then with a pair of scissors cut the bra cup you have into circles so they can fit into the small cup.
- You will now put these circles into the cups themselves. The bra cup circle will be placed by itself into the plastic cup labeled bra cup. Then you will put the rest of the circles on top of the other cups that contain another three amounts of soil, soil and sand, and soil, sand, and gravel.
- After this you will now pour the Kool-Aid into the cups themselves.
- Now let the Kool-Aid filter through the soil, sand, gravel, and bra cup.
ANALYZATION AND DATA FOUND:
- The hypothesis that a bra cup would work together with the sand, gravel, and soil was proven wrong. It seems the Soil, sand, and gravel worked better at filtration then when it had the bra cup with it.
That if you were in the wild using sand, gravel, and soil is the most effective way to filtrate brackish or "dirty" to drink if you have nothing but the supplies listed earlier.
