ADVANCED BATTERY TECHNOLOGY SCI/256 People‚ Science‚ and the Environment Environmental Science Dr. Larry Collins‚ Instructor SUMMORY There has been a huge increase in the need for energy worldwide for years‚ because of industrial developments and the population growth. As a result‚ there is a shortage of electricity and fuel causing the inflation of energy cost to go higher and higher. Police are directing traffic at gas stations‚ while angry frustrated people spend hours in line

Osmosis was clearly shown since the potato cylinders decreased or increased at different concentrations of sucrose. The results supported my hypothesis because for the 0.0 sucrose concentration the average percent change in mass was 16.9%. For the 0.2 concentration the percent change was 3

foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity. With the increased level of damage to the potato‚ there appeared to be more activity within the reaction between the catalase and the H2O2. b) Explain at the cell level why crushing or macerating the potato has this effect. When you crush or macerate the potato‚ you are breaking the cell walls of each individual cell. Once this happens‚ the catalase is

Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1.

Potatoes May Power The Batteries Of The Future Friday‚ June 18‚ 2010 - by Ray Willington Oh‚ batteries. Can’t live with ’em‚ can’t live without ’em. It sounds like a power ballad‚ but it’s the story of our lives around here. We’ve been dealing with lofty promises and batteries that kick the bucket far too early‚ for years now. And the fact that we’re still dealing with lead-acid batteries is sort of a baffling thing to wrap one’s mind around. But all of that just might be changing. We won’t get

Problem Statement versus Needs Assesment The determination of whether you write a problem statement or a needs assessment may hinge more on the funder’s priorities than your own passion for the project. Either way‚ the same information will be stated either as a reduction of what is currently a problem or an enhancement of a need to be added to a current situation. For example‚ let’s look at a fictitious rural community facing a particular environmental situation. The federal public land manager

Osmosis in Potato Conclusion The data we had did not support the definition of Osmosis‚ Osmosis is the diffusion of water through a partially permeable membrane from a region of lower solute concentration to a region of higher solute concentration; the data we collected did not seem to fit into this. The potato chips were suppose to lose more mass in the higher concentrated solution as the water from the potato chip will flow out to the higher concentrated solution as the water inside the potato has a

Biology Aim: My objective is to plan and conduct an experiment from which I should be able to draw a firm conclusion that will either prove or disprove any predictions I make. This essay aims to assess and investigate the effect of various solution concentrations on the activity of osmosis in plant tissue.
