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

Nitrate on Pond Water By Claudia Phillips September 6‚ 2014 Block Two INTRODUCTION This lab was designed to study and observe the effects of phosphate and nitrate applied to pond water (1). Phosphorous‚ commonly used in fertilizers‚ is a necessary and vital element for life but can enhance the effects of eutrophication (the over-enrichment of nutrients in water) (2). Nitrate is a common source of food for most algae‚ but too much can make living conditions in water harsh (3). They are

Water Quality and Contamination Melody McBride SCI-207 Dependence of man on the environment Robin Glenn September 28‚ 2014 Abstract The lab was conducted at the McBride residence. For this experiment vegetable oil‚ vinegar and liquid detergent was use to contaminate the water. Testing of how ground water is affected by different contaminants was the bases of the experiment. The results were interesting in that when vinegar is filtered through dirt it came out fairly clean‚ it also

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

Kaileah Diaz November 10‚2017 Period: 3 Weathering Lab Report Water erosion is usually caused by rainfall and runoff on a slope‚ and the magnitude of water erosion depends on the type of soil. This can occur on river banks‚ seashores‚ streams‚ or even seaside cliffs. Muddy water is also a sign of erosion. There are brown hue results from the suspension of rock and soil particles inside the water. Water erosion usually happens in the springtime because there is usually a lot more rainfall and

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

Water Quality Testing Pre-Lab Mrs. Susil-APES You and a partner will be performing water quality tests on water that you collected from a canal‚ lake‚ or pond. This lab will take two days to complete. You must wear proper laboratory attire (closed toed shoes‚ goggles‚ aprons‚ gloves) in order to participate in this lab. We will meet in the classroom across the hall from 8154. Numbers 1-4 below are due before the lab begins on Wednesday in your lab notebook: 1. Title

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

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater
