project is to determine whether river water or lake water is cleanest as it relates to tap water. The independent variables being tested in this experiment are the different waters being tested which are river water‚ lake water‚ and tap water‚ which is the control. The dependant variable is which of the three waters are the cleanest as it relates to unfiltered tap water. The purpose of this experiment is to determine what the different aspects of the three types of waters are and how that relates to cleanliness

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Condensation and evaporation are represented in the model. Condensation formed inside the jar and under the lid and the warm water evaporated. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Precipitation and infiltration did not get represented

The intention of the “Foul Water” lab was to purify a sample of sewage water and conserve as much as possible. The water should be clean enough to wash your hands with. My hypothesis is that the water will be cleaner than the initial water sample‚ but not to the standard that I would wash my hands with. Significant terms to know include purification‚ filtration‚ adsorption‚ volume‚ clarity‚ dissolved‚ filtrate‚ impurities‚ pipette‚ clay triangle‚ funnel cone‚ iron ring‚ beaker‚ and Erlenmeyer flask

This will allow it to absorb some carbon dioxide from the atmosphere and lower its pH from a level of about 7 to about 5.8. The distilled water will act as a model for "normal" rainwater‚ which has a pH of about

Fracking is currently regulated by the EPA under the clean water act of 2005 (EPA.gov). However‚ this only partially governs the methods of injecting fluids and the retrieval of such fluids into the earth. It does not govern the types of chemicals that are being allowed to be used‚ or how much fresh water is wasted (millions of gallons per “Frack job”) and it does not carry stiff enough penalties for spills or irreversible damage to community’s water supplies. For those of you‚ who are unfamiliar with

Hand Washing Experiment Outline I. Introduction a. This lab was conducted in order to understand and apply the scientific method. The experiment tested the effectiveness of reducing microorganism (bacteria) with the use of various hand soaps. b. Hypothesis: If the Harris Teeter Foaming Hand Soap is more effective in reducing bacterial growth than the Soft Soap hand soap‚ then there will be less bacterial/microorganism growth present on the agar plate for the Harris Teeter Foaming

purpose of this lab was to practice measuring the mass and volume of different samples and to calculate the density and specific gravity of those samples using the measurements. B. Equipment 1. Electronic balance- The electronic balance is a device used to measure the exact mass of an object 2. Graduated cylinder- The graduated cylinder is a tool used to measure the volume of a liquid 3. Pipets- Pipets are small tubes that suck up and contain liquids C. Technique 1. The water displacement technique

Lab Report: Hard Water Purpose: The purpose of this lab is to determine whether a liquid is hard water or not. Background: Hard water is the water that has a high amount of mineral in it‚ usually Ca2+ and Mg+. These cations enter the source of water by leaching from minerals within a wet underground layer of water- bearing rock‚ or an aquifer. According to the WHO‚ hard water is not harmful to human’s health but it’s a serious problem in the water industry. Household plumbing and appliances
