porousness/permeability Lab B2 Science The purpose of this research lab is to husking if the small string of bead or swelled string of beads begin more permeability (rate substance passes done post) and porousness ( fall of focalise space). My opening is that the large beads pull up stakes be high porosity and a alacritous permeability. The independent variables of this where the substance of piddle you barf in, and the dependent where the amount of beads in the tube. Materials: Tube, pee, beads, cup, beaker, gradational cylinder Procedure: Porosity: 1. Collect water and germinate it in the tube 2. Make sure you fill it up to the bankers bill of the beads 3. Collect selective information by amount of data you have 4. Do it with small and large beads 5. Comp ar results and attend, which holds more water 6. wont comparability to find porosity, ( deal Pores/ Total volume of bit measure snow permeability: 1. Determine amount of water you are victimization 2. Get timer 3. Pour certain amount in tube 4. Get time 5. Trial 3 times 6. Collect data from small& large beads 7. Compare results find which are is faster 8. Find pick out permeability by using equation (Volume of water/Time) Porosity Porosity Large: 35.47% Porosity teensy: 30.

I believe I got these results because in the large beads there is more space for water to flow and therefore will be a faster time than the small...If you insufficiency to get a all-encompassing essay, order it on our website: BestEssayCheap.com
